Advertising Regulations in Turkey Beyond KVKK: What Foreign Brands Need to Know
KVKK governs what you may do with data. A completely separate regime governs the advertisement itself — and it is enforced by a different authority with the power to fine you, stop your campaign and order a correction. Foreign brands entering Turkey often complete a thorough data protection review and then run campaigns that breach consumer protection law on the first day, because nobody told them the two regimes exist independently.
The governing instruments are Law No. 6502 on Consumer Protection and the Regulation on Commercial Advertising and Unfair Commercial Practices, published in the Official Gazette on 10 January 2015. Enforcement sits with the Advertising Board (Reklam Kurulu) under the Ministry of Trade.
This area changed substantially in 2026. A comprehensive amendment to the Regulation was published in the Official Gazette on 1 July 2026 (No. 33297) and took effect on 1 August 2026. It moved rules that previously sat in Ministry guidance documents into the Regulation itself — giving them stronger legal footing — and added new obligations covering social media influencers, targeted advertising, artificial intelligence in advertising, consumer reviews, environmental claims and discount pricing. If your Turkish compliance review predates August 2026, it is out of date.
This guide covers what the Advertising Board can do, what changed, the influencer disclosure rules foreign brands most often breach, sector-specific restrictions, and who carries liability when something goes wrong. It deliberately does not cover KVKK, which is a separate subject handled in our guide to KVKK compliance for foreign brands marketing in Turkey.

Two regimes, two regulators
The distinction is simple once stated, and it prevents most of the confusion in this area.
| Data protection | Advertising content | |
|---|---|---|
| Governs | Collection and processing of personal data | What the advertisement says, shows and implies |
| Main instrument | KVKK (Law No. 6698) | Law No. 6502 and the Commercial Advertising Regulation |
| Authority | Personal Data Protection Authority | Advertising Board, Ministry of Trade |
| Typical trigger | Consent, transfer, retention | Misleading claim, hidden advertising, unsubstantiated comparison |
A campaign can be fully KVKK-compliant and still be stopped and fined. The reverse is also true. Additional regimes sit alongside both — sector regulators, broadcast rules under RTÜK, and commercial electronic messaging law — which is why “we did the legal review” usually means one of five reviews was done.
What the Advertising Board can actually do
The Advertising Board supervises commercial advertising and unfair commercial practices. Where it finds a breach, its available sanctions include ordering the advertisement stopped, requiring a correction published by the same method, imposing administrative fines, and applying an interim suspension where it considers immediate action necessary.
Three features of how it works matter to foreign brands.
It acts on complaints, including from competitors. A rival, a consumer or an association can complain, and complaints from competitors are a meaningful enforcement channel in contested categories.
Its decisions are published. The Ministry of Trade publishes Board decisions, which means an adverse finding carries reputational exposure beyond the fine, and your Turkish competitors will see it.
Fine levels are not set arbitrarily. Law No. 6502 requires the Board to take specified factors into account when setting the amount, including the unfairness of the breach and its effect on public order, the size of the illegitimate benefit obtained or the harm caused, and the economic situation and scale of the business. A large international advertiser should not assume it will be treated like a small local one.
What changed on 1 August 2026
The amendment published on 1 July 2026 (Official Gazette No. 33297), effective 1 August 2026, is the most significant update to Turkish advertising rules in years. Its stated rationale was consumers’ increased exposure to advertising through digitalisation.
Structurally, the most important change is that provisions previously contained in Ministry guidance documents — the guide on social media influencers, the guide on environmental claims, the 2024-updated guide on price information and discounted sale advertising, and the guide on consumer reviews — were moved into the Regulation itself. Guidance became binding regulation.
The amendment also added definitions of “environmental claim,” “social media,” “social media influencer” and “consumer reviews” to the Regulation, introduced explicit rules on targeted advertising and the use of artificial intelligence in advertising, revised the basis for calculating pre-discount prices, and reorganised sector-specific advertising restrictions.
The practical point for any brand already operating in Turkey: obligations that a lawyer might previously have described as “guidance the Board applies in practice” are now regulation text. The compliance question changed from interpretive to binary.
Influencer disclosure: the rules most often broken
Turkey regulates influencer advertising more prescriptively than most markets foreign brands come from, and this is where enforcement is most visible.
The framework began with the Advertising Board’s principle decision of 4 May 2021 (meeting 309, decision 2021/2), which led the Ministry of Trade to publish the Guide on Commercial Advertising and Unfair Commercial Practices by Social Media Influencers. Its core rules are now reinforced by the 2026 Regulation amendment.
Disclosure is mandatory whenever the influencer received a benefit. The benefit does not have to be money. Free or discounted products, gifted items, event access and similar in-kind benefits all trigger the obligation.
The disclosure must be visible on first encounter. It has to be seen without the user scrolling the screen or expanding a caption. Burying the tag at the end of a long description does not comply.
The wording is prescribed, and hashtags alone are not enough. Under Article 23/A the content must carry either “Reklam” (advertisement) or “Tanıtım” (promotion) — one of those two words is mandatory. Tags such as #işbirliği, #ortaklık or #sponsor do not satisfy the requirement on their own. In addition, the content must identify the advertiser by name or trade name, or include one of the explanatory statements set out in the Regulation. The compliant pattern is therefore the mandatory word plus identification of the advertiser, not a single collaboration hashtag. An English “#ad” is not the local standard.
Audio content has a specific rule. For audio-only sharing, the disclosure must be made at the beginning of the broadcast and before the advertisement itself.
An influencer may not endorse something they have not used. Posting about a product in a way that creates the impression of having experienced it, when they have not, is prohibited.
Follower count is irrelevant. The obligation attaches to the commercial nature of the content, not to audience size, and applies to micro-creators and personal accounts as much as to large ones.
For foreign brands the operational implication is that disclosure compliance cannot be delegated by assumption. Put the specific label requirements in the creator contract, require the creator to send the post for review before publication, and check that the label is visible in the delivered format — not just present in the caption text. The commercial side of working with Turkish creators is covered in our guide to influencer marketing in Turkey.
Discount and price claims
The 2026 amendment rewrote how the pre-discount price must be established, and the new rule is strict.
The price shown as the “before” price must be based on the lowest price applied in the ten days preceding the start of the discount. For perishable goods and for services, the price applied immediately before the discounted price is taken as the basis. The pre-discount price must be determined by reference to the price in the sales channel where the discount is applied — so a higher price on another channel cannot be used to inflate the apparent saving.
The Regulation also brings loyalty programme pricing and campaigns conditional on specific purchase behaviour within scope under defined conditions.
This matters disproportionately for foreign brands running marketplace and e-commerce operations in Turkey, where promotional pricing is frequent and often managed by systems configured for other markets. A pricing engine that sets the reference price from a global list price or an RRP will produce non-compliant advertising in Turkey. Audit the logic, not just the creative. The commercial context sits in our guide to e-commerce in Turkey.
Consumer reviews
Consumer reviews are now defined in the Regulation and subject to express rules, having previously been addressed through guidance.
The rules are concrete rather than general. Only consumers who have actually purchased the relevant good or service may leave a review. Reviews taken from other media, where the purchase process cannot be verified, may not be published. And positive and negative reviews alike must be published in accordance with the principles set out in the Regulation, without discrimination between them.
That last point removes a common practice outright. Filtering out unfavourable reviews, or surfacing only positive ones, is not a presentational choice under Turkish rules. Neither is importing reviews from a global site or a third-party platform where you cannot demonstrate that the reviewer purchased the item.
Because review display is usually a platform or plugin function rather than a marketing decision, this is another area where the compliance question belongs with whoever configures the system. Ask specifically how reviews are collected, moderated, ordered and aggregated.
Targeted advertising and AI
The 2026 amendment introduced explicit provisions on targeted advertising based on consumers’ personal data, and on the use of artificial intelligence in advertising. Legal commentary on the amendment notes that the targeted advertising provisions require substantial compliance work from e-commerce platforms and digital advertising intermediaries in particular.
Two points for foreign advertisers.
First, targeted advertising now engages both regimes. KVKK governs the lawfulness of processing the data; the advertising Regulation now governs how the resulting targeted advertising may be presented. Satisfying one does not satisfy the other.
Second, the Regulation sets two concrete rules on artificial intelligence in advertising. Where an advertisement features a digital character created using AI that cannot be distinguished from a human, that fact must be stated clearly, comprehensibly and distinguishably. And advertisements are prohibited where an AI-generated digital replica of a real person creates the false impression that the person has personally experienced, used or recommended a good or service.
Both rules bite directly on practices that have become routine in international advertising production — synthetic presenters and AI-generated likenesses of real people. Neither can be deployed in Turkey on the assumption that global practice transfers.
Because the detailed obligations are new and their administrative application is still developing, get a current reading from a Turkish lawyer rather than relying on any summary — including this one.
Environmental claims
“Environmental claim” is now a defined term in the Regulation, covering statements or visuals asserting that a product or service provides environmental benefit, or that its negative environmental impact has been reduced or eliminated — across components, production, market placement, presentation, use or disposal.
For international brands this is a common exposure point, because global sustainability messaging is typically written to a different standard and then translated for local markets. Claims such as carbon-neutral, eco-friendly, recyclable or environmentally friendly need substantiation that holds under Turkish rules, in Turkish, at the point of sale. A claim that is defensible in your home market’s regulatory framework is not automatically defensible here.
Sector-specific restrictions
Several categories face restrictions that go far beyond disclosure rules, and in some cases amount to complete prohibition. These sit in their own legislation, separate from the consumer protection framework.
- Tobacco. Law No. 4207 prohibits advertising, promotion and sponsorship of tobacco products and producer brands. The prohibition is comprehensive and extends across media.
- Alcohol. Article 6 of Law No. 4250, as amended in 2013, prohibits advertising and consumer-facing promotion of alcoholic beverages in any form, along with campaigns, promotions and events encouraging their use or sale. These prohibitions apply to digital channels and influencer collaborations as they do to traditional media.
- Betting and gambling. Under Law No. 7258, advertising unlicensed betting sites is a criminal offence. Only licensed operators may be promoted, and this is an area of active enforcement.
- Human medicinal products. Consumer-facing advertising of prescription medicines is prohibited, and health claims on other product categories are tightly controlled. The 2026 amendment reorganised where these restrictions sit within the Regulation.
- Food supplements and health claims. A significant area of Advertising Board enforcement. Notably, the 2026 amendment removed the comparative advertising prohibition that had applied specifically to food supplements — an example of the rules moving in both directions, and a reason to verify the current position rather than relying on older summaries.
- Cosmetics. Claims that exceed the regulatory definition of a cosmetic product — for instance by asserting a therapeutic indication — have attracted Board action, including against major international advertisers.
- Regulated professions. Healthcare providers, lawyers and pharmacists face profession-specific advertising restrictions under their own regimes.
Health and wellness categories carry enough regulatory complexity to warrant separate treatment; see our guide to healthcare and wellness marketing in Turkey.
Commercial electronic messages and İYS
Email, SMS and similar direct messaging sit under a further regime: Law No. 6563 on the Regulation of Electronic Commerce and its associated regulation, operated through İYS (İleti Yönetim Sistemi), the national message management system. Commercial electronic messages to consumers generally require prior consent recorded through that system.
This is distinct from both KVKK and the advertising Regulation, and is frequently missed because foreign teams assume that a GDPR-style consent record is sufficient. It is not — İYS is an operational system with registration and timing obligations, not merely a legal standard. Our guide to email marketing in Turkey covers the practical side.
Who is liable
A frequent misconception among foreign brands is that engaging a local agency or a creator transfers regulatory risk. It does not, in the way people assume.
The Turkish framework addresses obligations to multiple parties in the advertising chain — advertisers, advertising agencies, media organisations, social media influencers and e-commerce platforms — and commentary on the 2026 amendment notes that all of these parties needed to bring their practices into line by the August 2026 effective date.
As the advertiser, you are the party whose product is being promoted and whose claims are at issue. Contractual allocation of responsibility with an agency or creator governs who bears the cost between you, but it does not determine who the regulator approaches. Build compliance into the workflow — pre-publication review, label verification, claim substantiation files — rather than into the indemnity clause alone. This is one of the things worth probing when choosing a digital marketing agency in Turkey.
Penalties and challenging them
Administrative fines under Law No. 6502 are revised annually in line with the revaluation rate. The Ministry of Trade announced that fines applied under the Law increased by 25.49 percent from 1 January 2026, with the applicable amounts set out in the annual communiqué published in the Official Gazette on 23 December 2025.
Upper limits vary by the medium in which the advertising appeared, with higher ceilings for wider-reach media. Because these figures change every year, budget against the current communiqué rather than any figure quoted in an article — including this one, which deliberately does not reproduce them.
Board decisions can be challenged, but the window is short and sources describing the deadline are not consistent. Treat any Board notification as immediately time-critical and involve Turkish counsel on receipt rather than after internal review. Do not let a decision sit in a regional legal queue.
A practical compliance checklist
- Substantiate every claim before publication and keep the evidence file. Turkish enforcement focuses heavily on whether claims can be proven.
- Review pricing logic, not just creative, against the ten-day lowest-price rule and the same-channel requirement.
- Put the Article 23/A wording in creator contracts — the mandatory “Reklam” or “Tanıtım” plus advertiser identification — with a pre-publication review step.
- Check label visibility in the delivered format, not just in the caption.
- Re-examine environmental claims in Turkish, against the Regulation’s definition rather than your global sustainability guidelines.
- Audit how consumer reviews are collected, ordered and displayed.
- Confirm your category’s specific restrictions before building a channel plan around advertising.
- Treat KVKK, the advertising Regulation and İYS as three separate reviews.
- Re-verify anything reviewed before August 2026.
Common mistakes
Assuming a KVKK review covers advertising compliance. Different law, different regulator, different exposure.
Relying on a collaboration hashtag alone. “Reklam” or “Tanıtım” is mandatory and the advertiser must also be identified; #işbirliği, #ortaklık, #sponsor or an English “#ad” do not satisfy Article 23/A by themselves.
Treating gifted product as outside disclosure rules. In-kind benefit triggers the obligation.
Placing the disclosure below the fold of a caption. It must be visible on first encounter, without the user scrolling the screen or expanding anything.
Importing global sustainability claims unchanged. Environmental claims are now expressly defined and regulated.
Setting reference prices from a global list price. The ten-day, same-channel rule governs.
Believing an agency contract transfers regulatory liability. It allocates cost, not regulatory attention.
Working from pre-August 2026 guidance. The rules moved from guidance into regulation and changed substantively at the same time.
Frequently asked questions
Who regulates advertising in Turkey?
The Advertising Board (Reklam Kurulu), operating under the Ministry of Trade, supervises commercial advertising and unfair commercial practices under Law No. 6502 and the Regulation on Commercial Advertising and Unfair Commercial Practices. It can order advertising stopped, require corrections, impose administrative fines and apply interim suspensions. Sector regulators and broadcast authorities have additional jurisdiction in their own areas.
Do influencers in Turkey have to disclose paid partnerships?
Yes. Disclosure is required whenever the influencer received any benefit, including free or discounted products rather than only money, and it applies regardless of follower count. Under Article 23/A the content must carry either “Reklam” or “Tanıtım” and must identify the advertiser by name or trade name, or include one of the explanatory statements set out in the Regulation. The disclosure must be visible on first encounter, without scrolling the screen.
Is “#ad” acceptable in Turkey?
No. The Regulation requires the Turkish word “Reklam” or “Tanıtım” in the content, together with identification of the advertiser by name or trade name, or one of the explanatory statements the Regulation sets out. An English “#ad” does not meet that requirement, and neither does a collaboration hashtag such as #işbirliği on its own.
How do I calculate a “before” price for a discount campaign in Turkey?
Since the 2026 amendment, the pre-discount price is based on the lowest price applied in the ten days before the discount begins, determined by reference to the sales channel where the discount runs. Perishable goods and services use the price applied immediately before the discounted price.
Does complying with KVKK mean my advertising is compliant?
No. KVKK governs personal data processing. The content of the advertising is governed separately under Law No. 6502 and the Commercial Advertising Regulation, enforced by a different authority. Targeted advertising now engages both regimes simultaneously.
Can my Turkish agency take on the regulatory risk?
You can allocate cost contractually, but obligations under the framework extend across the advertising chain, and as the advertiser you remain the party whose claims are at issue. Compliance is better handled through pre-publication review and substantiation files than through indemnity clauses.
Conclusion
Turkish advertising regulation is not unusually harsh, but it is more prescriptive than many foreign brands expect — particularly on influencer disclosure, discount pricing and substantiation — and it changed significantly in August 2026 when a large body of Ministry guidance became binding regulation.
The practical approach is to stop treating “Turkish compliance” as a single exercise. Data protection, advertising content and commercial electronic messaging are three separate regimes with three separate authorities, and a brand can pass one while failing another on the same campaign. Build claim substantiation, label verification and pricing logic into the production workflow rather than reviewing creative at the end, and get anything reviewed before August 2026 looked at again.
This article is general information based on published legislation and professional commentary as at the date shown. It is not legal advice. Regulations, guidance and enforcement practice change, and the treatment of any specific campaign depends on its facts. Confirm your position with a qualified Turkish lawyer before acting.
