Turkish advertising law operates through a multi-layered regulatory framework that applies simultaneously to every commercial communication directed at Turkish consumers — from a television spot to an Instagram story, from a billboard to a podcast sponsorship. The core statute is the Law on the Protection of Consumers (Tüketicinin Korunması Hakkında Kanun, Law No. 6502), which establishes the general prohibition on misleading and unfair commercial practices, and the Commercial Advertising and Unfair Commercial Practices Regulation (Ticari Reklam ve Haksız Ticari Uygulamalar Yönetmeliği) issued under it, which sets out the detailed standards for advertising content and format. The Radio and Television Supreme Council (RTÜK) imposes additional rules on broadcast and streaming advertising. The Advertising Board (Reklam Kurulu) under the Ministry of Trade investigates complaints and imposes sanctions. Sector-specific regulatory bodies — the BDDK, SPK, Health Ministry, and others — overlay further restrictions in their respective regulated areas. And the Turkish Personal Data Protection Law (KVKK) applies a consent and transparency layer to any advertising that involves the processing of user data. Understanding Turkish advertising law means understanding how these frameworks interact for a specific campaign in a specific sector — not just knowing that "misleading advertising is prohibited." The primary advertising regulation is accessible at Mevzuat. This guide explains how each layer of Turkish advertising law works and what it means in practice for brands, agencies, and influencers operating in Turkey.
The general prohibition on misleading advertising
A lawyer in Turkey advising on the basic standard of Turkish advertising law must explain that the Commercial Advertising Regulation prohibits misleading advertising (yanıltıcı reklam) — defined as any advertising that, in its overall presentation, creates a false impression in the minds of the consumers it reaches, regardless of whether any individual claim in the advertisement is literally accurate. The overall impression test is the most important concept in Turkish advertising compliance: a court or the Advertising Board will assess the advertisement as a typical consumer would receive it — considering the visual presentation, the audio, the text, the images, the timing, and the omissions — and will ask whether that overall impression is truthful. An advertisement that uses technically accurate statistics in a context that creates a misleading overall impression can violate the prohibition just as clearly as one that makes an outright false claim. Practice may vary — verify current Advertising Board published decisions in the relevant sector before relying on any specific compliance approach for a campaign that uses performance claims or statistical comparisons.
An Istanbul Law Firm advising on the substantiation requirement must explain that the Commercial Advertising Regulation requires that advertising claims be substantiated by evidence — and where an advertiser makes a factual claim about a product's performance, efficacy, or characteristics, the advertiser must be able to produce the supporting evidence before or during an Advertising Board investigation. The substantiation standard varies by claim type: a superlative claim ("Turkey's best") requires market research or other objective comparative evidence; a performance claim ("reduces cholesterol by 15%") requires clinical or scientific evidence appropriate to the claim; a pricing claim ("lowest prices guaranteed") requires a price monitoring methodology that genuinely supports the guarantee. Advertising that makes claims the advertiser cannot substantiate is presumptively misleading regardless of whether the claim is factually accurate — because the advertiser cannot prove it is. Practice may vary by authority and year — check current Advertising Board guidance on the substantiation standard applicable to specific claim types in your sector before finalizing campaign content.
Sector-specific advertising restrictions
A law firm in Istanbul advising on sector-specific restrictions must explain that several sectors in Turkey are subject to advertising restrictions that go beyond — and in some cases completely override — the general misleading advertising standard. Pharmaceutical advertising to the general public is prohibited entirely under Turkish pharmaceutical law: prescription medicines cannot be advertised at all, and over-the-counter medicines can only be advertised within the strict content and format limits set by the Ministry of Health. Healthcare services advertising is separately regulated, with specific restrictions on before-and-after imagery, outcome guarantees, and testimonials. Alcohol advertising faces both content restrictions (no association with driving, sport, or youth) and channel restrictions (prohibited on certain platform types and during certain broadcast times). Tobacco advertising is comprehensively prohibited across all channels. Practice may vary by authority and year — check current sector-specific regulations from the relevant ministry or regulator before designing any advertising campaign in a restricted category, as the specific rules change and are enforced with varying intensity across sectors.
An English speaking lawyer in Turkey advising on financial services advertising restrictions must explain that advertising for banking products, credit, investment products, and insurance in Turkey is regulated not only by the general Advertising Regulation but also by the BDDK (Banking Regulation and Supervision Agency) and SPK (Capital Markets Board), each of which has issued specific communication guidelines for the products they regulate. A credit advertisement in Turkey must comply with BDDK requirements on mandatory disclosures including the annual percentage rate (APR), total repayable amount, and representative example — and a failure to include required disclosures makes the advertisement non-compliant regardless of whether its substantive claims are accurate. Investment product advertising must comply with SPK requirements on risk disclosure and prohibited return guarantees. A brand advertising financial products in Turkey should assume that both the general Advertising Regulation and the sector regulator's specific communication rules apply simultaneously. Practice may vary — verify current BDDK and SPK communication requirements before finalizing financial services advertising content or format.
Comparative advertising rules
A Turkish Law Firm advising on comparative advertising must explain that Turkish law permits comparative advertising — advertising that directly or indirectly identifies a competitor or a competitor's products — only where the comparison meets a specific set of conditions: it must compare like with like (products meeting the same need or intended for the same purpose); it must objectively compare one or more material, relevant, verifiable, and representative characteristics; it must not be misleading; it must not denigrate or discredit the competitor's marks, trade names, products, activities, or circumstances; and it must not create confusion between the advertiser and the competitor. A comparative advertisement that satisfies all of these conditions is lawful; one that fails any single condition creates exposure to an Advertising Board complaint, an unfair competition civil claim under the Turkish Commercial Code, and potentially a trademark infringement claim. Practice may vary by authority and year — verify current Advertising Board published decisions on comparative advertising in your specific sector before running a campaign that identifies competitors, as the standards are applied case-by-case with significant fact-sensitivity.
A lawyer in Turkey advising on the denigration prohibition in comparative advertising must explain that the boundary between a lawful factual comparison and a prohibited denigrating comparison is the most litigated question in Turkish comparative advertising law. A comparison that factually states a competitor's product has fewer features than the advertiser's product, supported by objective evidence, is generally lawful. A comparison that presents the competitor's product as unsafe, inferior in ways that go beyond the stated comparison, or that uses imagery or language that ridicules or demeans the competitor's brand, is prohibited denigration. The Advertising Board makes this assessment based on the overall impression created by the comparison — not merely the literal words used — and has found denigration in cases where the factual claims in the comparison were accurate but the overall presentation created an unfairly negative impression of the competitor. Practice may vary — verify current Advertising Board denigration standards for the specific comparison format being considered before campaign launch.
Influencer marketing and disclosure obligations
An Istanbul Law Firm advising on influencer marketing law must explain that the Turkish Advertising Board has issued specific guidance treating paid influencer content as commercial advertising subject to the full requirements of the Commercial Advertising Regulation — including the prohibition on misleading content and the requirement that the commercial nature of the content be clearly disclosed. The required disclosure format for Turkish influencer content includes: visible hashtags at the beginning of the caption (#reklam, #sponsorlu, or #işbirliği); on-screen text labels in video content displayed prominently and for sufficient duration; and verbal disclosure in audio content. A disclosure that appears only at the end of a long caption, that is formatted in a way that blends with other hashtags, or that is omitted from stories while appearing only in feed posts, does not satisfy the disclosure requirement. Both the brand and the influencer can be subject to Advertising Board complaints and fines for non-compliant disclosure. Practice may vary — check current Advertising Board guidance on platform-specific disclosure format requirements, as these have been updated to address new content formats including short-form video and collaborative posts.
An English speaking lawyer in Turkey advising on influencer agreements must explain that a legally sound influencer contract for the Turkish market must specifically address: the disclosure requirement and the consequences (including indemnification) of non-compliant disclosure by the influencer; the brand's content approval right before publication; the intellectual property ownership of content created during the collaboration; the exclusivity scope and duration; the influencer's representations about audience authenticity and engagement; the brand's right to use and repurpose the content after the campaign period; and the moral clause triggering the brand's right to terminate if the influencer's conduct creates reputational risk. For international campaigns — where the brand is foreign and the influencer is Turkish, or vice versa — the governing law and dispute resolution clause must be specifically selected. A contract that addresses all of these elements explicitly creates a substantially smaller dispute risk than one that addresses only payment and deliverables. The consumer protection laws in Turkey framework — covering the regulatory context for influencer marketing — is analyzed in the resource on consumer protection laws in Turkey. Practice may vary by authority and year — verify current Turkish tax treatment of influencer income and applicable withholding obligations before finalizing the payment structure.
The Advertising Board: complaint process and sanctions
A law firm in Istanbul advising on Advertising Board proceedings must explain that the Reklam Kurulu investigates advertising complaints from three sources: consumer complaints filed through the Ministry of Trade's consumer complaint portal; competitor complaints filed directly with the Board; and the Board's own monitoring unit, which proactively reviews advertising across media. When a complaint is filed, the Board notifies the advertiser and typically allows a defined period for a written response. The advertiser's written response is the primary opportunity to present the factual and legal defense — including the substantiation evidence for challenged claims, the legal basis for the advertising format used, and any relevant Advertising Board precedents. A response that engages specifically and thoroughly with the complaint's allegations substantially improves the outcome prospects. Practice may vary — verify current Advertising Board procedural rules on response deadlines and format before submitting any defense to a pending investigation.
A Turkish Law Firm advising on the sanctions available to the Advertising Board must explain that the Board can impose several types of sanction, either individually or in combination: a written warning (uyarı); a monetary fine calculated per day of non-compliant advertising, subject to an annual statutory maximum; a corrective advertising order requiring the advertiser to publish a correction at equivalent prominence to the non-compliant advertisement; a suspension order prohibiting further broadcast or publication of the non-compliant advertisement; and referral to criminal or civil enforcement authorities where the advertising conduct rises to the level of fraud or unfair competition under other laws. The most commercially significant sanction in practice is the suspension order combined with the daily fine — because a campaign that has been running for weeks before the complaint is resolved may face a substantial cumulative fine for the entire non-compliant period. The commercial litigation Turkey framework — covering administrative court appeals of Advertising Board decisions — is analyzed in the resource on commercial litigation Turkey. Practice may vary by authority and year — check current Advertising Board fine calculation methodology and the administrative court appeal procedure before deciding on the response strategy.
Digital advertising and data protection
A lawyer in Turkey advising on KVKK compliance for digital advertising must explain that the intersection of digital advertising and Turkish data protection law is defined by the KVKK's requirement that all personal data processing — including the collection, storage, and use of data for advertising targeting purposes — must have a valid legal basis. For behavioral advertising that uses cookies, device identifiers, or cross-site tracking to target users based on their online activity, the applicable legal basis under KVKK is the user's explicit and informed consent (açık rıza). This consent must be actively given — not implied by use of the website, not pre-ticked, and not buried in general terms and conditions. The consent mechanism must be as easy to withdraw as it is to give, and the website must function meaningfully if the user declines advertising consent. A website's cookie banner that presents "Accept All" prominently and makes "Decline" difficult to find or access does not collect valid KVKK consent. Practice may vary — verify current KVKK Board decisions on cookie consent mechanics before implementing or updating a consent management platform for Turkish users.
An Istanbul Law Firm advising on email and SMS marketing compliance must explain that direct marketing by electronic communication — email, SMS, and app push notifications — to Turkish consumers is regulated by the Electronic Commerce Law (Law No. 6563) and its implementing regulations, which require prior explicit commercial communication consent (ticari elektronik ileti onayı) before sending any promotional message. The consent must be obtained through a clearly identifiable consent mechanism that is separate from other terms and conditions, and the consent record must be maintained with a timestamp and user identifier for five years. A Turkish company that sends marketing emails to Turkish subscribers without prior consent, or that purchased a subscriber list without verifying consent status, is exposed to fines from the Information Technologies and Communication Authority (BTK) as well as consumer complaints under the Electronic Commerce Law. Practice may vary by authority and year — verify current BTK commercial electronic communication consent requirements and the specific format of a compliant consent record before launching any email or SMS marketing campaign to Turkish users.
Brand protection and IP in advertising
A law firm in Istanbul advising on intellectual property in advertising must explain that every commercial advertisement involves intellectual property — the creative concept, the script, the visual design, the music, the photography, the voice performance, and in some cases the performers' image and personality rights — and each element requires either ownership or a specifically documented license that covers the channels, territories, and duration of the campaign's use. The most common and costly IP compliance failures in Turkish advertising practice involve: using music under a license that covers broadcast but not digital, then publishing the advertisement online; using a stock photograph under a personal or editorial license that does not permit commercial advertising use; continuing to use advertising content after the licensed period expires; and failing to obtain separate personality rights agreements from performers who appear in the advertisement. Practice may vary — verify current FSEK copyright provisions and the specific license scope for each content element before approving a campaign for publication.
An English speaking lawyer in Turkey advising on responding to a third-party IP complaint must explain that a competitor or rights holder who believes their intellectual property has been used without authorization in an advertisement has three parallel enforcement routes in Turkey: an Advertising Board complaint (faster, administrative, no damages); a civil infringement lawsuit at the competent intellectual property court (slower, but can produce injunctions and damages); and a complaint to TÜRKPATENT for trademark-related infringement. All three routes can be pursued simultaneously, and a respondent brand that receives a third-party IP complaint in an advertising context should assess its exposure across all three forums before deciding on a response strategy. The enforcement proceedings Turkey framework — covering intellectual property judgment enforcement and injunctive relief — is analyzed in the resource on enforcement proceedings Turkey. Practice may vary by authority and year — verify current Turkish IP court procedural requirements and interim injunction standards before filing or responding to an advertising-related IP claim.
Children's advertising and protected audience rules
A Turkish Law Firm advising on children's advertising must explain that Turkish advertising law treats advertising directed at children or likely to be seen by children as a specially regulated category with heightened standards. The Commercial Advertising Regulation prohibits advertising directed at children that exploits their inexperience or credulity, that applies direct purchase pressure through appeals to parents, or that creates an impression that possession of the advertised product will give the child superiority over peers. RTÜK separately regulates advertising content in children's broadcast programming, including restrictions on advertising duration, prohibited product categories during children's programming, and content standards for advertisements shown during times when children are likely to be watching. Food and beverage advertising to children faces specific restrictions under Ministry of Health guidance on products high in fat, sugar, or salt. Practice may vary — check current RTÜK children's programming advertising rules and Ministry of Health food advertising guidance before finalizing any advertising placement or content targeting children or aired during children's programming.
Outdoor and print advertising requirements
A lawyer in Turkey advising on outdoor and print advertising compliance must explain that outdoor advertising in Turkey — billboards, transit advertising, street furniture, and point-of-sale materials — is regulated at two levels: the general Advertising Regulation's content standards apply to all outdoor advertising just as they apply to broadcast and digital, and municipal licensing requirements apply to the physical placement of outdoor advertising structures. A municipality can remove unlicensed outdoor advertising and impose administrative fines on both the advertiser and the outdoor media owner. The content standards apply in full: an outdoor advertisement that makes an unsubstantiated claim, that fails to include required disclosures for regulated products, or that uses prohibited comparative language is non-compliant regardless of the medium in which it appears. For national campaigns that use outdoor across multiple municipalities, each municipality's licensing requirements must be separately verified. Practice may vary by authority and year — check current municipal licensing requirements in each relevant municipality and verify that the outdoor advertising content complies with the general Advertising Regulation before production and installation.
An English speaking lawyer in Turkey advising on print advertising compliance must explain that print advertising in newspapers, magazines, and catalogues is subject to the same Commercial Advertising Regulation content standards as other media, but with one specific additional consideration: print advertising for certain regulated products must include required disclaimers or warnings in legible minimum font sizes that are specified by the relevant sector regulation. A pharmaceutical advertisement in a professional medical journal that uses a font size below the regulatory minimum for the required prescribing information is non-compliant even if every substantive claim it contains is accurate. The same principle applies to financial product advertising (required APR disclosure), food supplement advertising (required health claim disclaimers), and certain other categories. Ensuring that print advertising meets both the content and the format requirements of the applicable regulations requires reviewing both the general Advertising Regulation and the sector-specific rules. Practice may vary — verify current sector-specific print advertising format requirements before finalizing print production for regulated product categories.
Pre-campaign legal clearance
A law firm in Istanbul advising on pre-campaign legal clearance must explain that the most cost-effective way to manage Turkish advertising law risk is to identify compliance issues before the campaign is produced and published — rather than responding to Advertising Board complaints or competitor challenges after launch. A pre-campaign legal clearance review examines the campaign across five dimensions: the claims made (are they substantiated, non-misleading, and compliant with sector-specific rules?); the visual and audio content (does it comply with RTÜK, children's advertising, and specific format requirements?); the channel plan (do the planned channels include any that are prohibited for the product category?); the data processing implications (does the campaign require KVKK consent, and if so, is the consent mechanism compliant?); and the intellectual property position (is every element of the creative properly licensed for the planned use?). A written clearance opinion that identifies specific issues and required modifications before production gives the advertiser and agency a roadmap for compliance that is substantially cheaper than post-launch enforcement defense. Practice may vary by authority and year — check current Advertising Board enforcement priorities before final clearance decisions, as enforcement focus shifts over time.
A best lawyer in Turkey completing a pre-campaign clearance mandate delivers a written opinion within a defined turnaround that is specific enough to be actionable — identifying the precise content elements that require modification, the specific legal provision that requires the modification, and the specific format that would satisfy the requirement. A clearance opinion that says only "the campaign is broadly compliant with Turkish advertising law" is not a useful document for a production team or a compliance officer. We provide page-by-page, claim-by-claim review for high-stakes campaigns and channel-level reviews for multi-channel launches.

Frequently Asked Questions
- What is the main law governing advertising in Turkey? The Law on the Protection of Consumers (No. 6502) and the Commercial Advertising and Unfair Commercial Practices Regulation issued under it. Broadcast advertising is additionally regulated by RTÜK Law No. 6112. Sector-specific restrictions apply in pharmaceuticals, finance, alcohol, tobacco, and other regulated categories.
- Who enforces Turkish advertising law? The Advertising Board (Reklam Kurulu) under the Ministry of Trade is the primary enforcement body for general advertising. RTÜK enforces broadcast and streaming advertising rules. Sector regulators (BDDK, SPK, Ministry of Health) enforce sector-specific advertising restrictions. Civil courts handle infringement and unfair competition claims.
- What is the "overall impression" test? Turkish advertising law assesses whether an advertisement is misleading based on the overall impression it creates in the minds of the consumers it reaches — not merely whether each individual claim is technically accurate. An advertisement can be misleading even if no single statement in it is false.
- Can I advertise medicines in Turkey? Prescription medicines cannot be advertised to the general public at all. Over-the-counter medicines can be advertised within strict Ministry of Health content and format limits. Healthcare service advertising is subject to separate specific restrictions.
- Is comparative advertising allowed in Turkey? Yes, if the comparison is objective, verifiable, non-misleading, non-denigrating, and compares products serving the same need. A comparison that meets all conditions is lawful; one that fails any single condition creates legal exposure.
- Do influencers need to disclose paid partnerships? Yes. Turkish advertising law treats paid influencer content as commercial advertising. The disclosure must be clear, prominent, and positioned at the beginning of the content — not at the end of captions or in small print.
- What can the Advertising Board do if I violate the rules? Warnings, monetary fines (calculated per day of non-compliance), corrective advertising orders, campaign suspension orders, and referral to other enforcement authorities.
- Does Turkish advertising law apply to foreign brands targeting Turkish consumers? Yes — Turkish advertising law applies based on where the advertising communication is received, not where the advertiser is incorporated or where the content is produced.
- What IP rights do I need for an advertising campaign? Separately documented licenses (or ownership) for every creative element — music, photography, video footage, scripts, voice performances, and performers' personality rights — covering the specific channels, territories, and duration of the campaign.
- What is a pre-campaign clearance review? A legal review of campaign content, claims, channel plan, data processing implications, and IP position before production or publication — to identify compliance issues while modification is still commercially practicable.
