A 2026 legal guide to advertising compliance for foreign sports brands in Turkey, covering influencer marketing, sponsorship disclosures, misleading claims, discounts, personal data, electronic messages, image rights, and legal remedies.

Turkey offers significant commercial opportunities for international sportswear manufacturers, fitness companies, equipment suppliers, nutrition businesses, sponsors, sports technology platforms, and other sports-related brands. However, advertising campaigns aimed at Turkish consumers must comply with an increasingly strict regulatory framework.

Sports brands commonly market their products through professional athletes, sports clubs, influencers, sponsorship agreements, social media campaigns, competitions, discount promotions, and personalized digital advertising. Each method may create separate obligations under consumer protection, advertising, intellectual property, personal data, e-commerce, and unfair competition rules.

In 2026, enforcement remains particularly important. The Ministry of Trade announced that administrative fines imposed under consumer legislation increased for 2026, with penalties for misleading advertising and unfair commercial practices potentially ranging from TRY 99,339 to TRY 39,916,524 depending on the nature, scale, medium, benefit obtained, harm caused, fault, and economic circumstances of the violation.

Foreign sports brands should therefore review campaigns before publication rather than attempting to correct violations after regulatory action begins.

Main Advertising Rules Applicable to Sports Brands

The principal framework is based on Turkish consumer protection legislation and the rules governing commercial advertisements and unfair commercial practices.

Advertisements must generally be:

• accurate,
• identifiable as advertising,
• supported by evidence,
• consistent with fair competition,
• and presented without misleading consumers.

Responsibility may extend beyond the sports brand. Advertising agencies, media providers, influencers, endorsing athletes, digital platforms, distributors, and local subsidiaries may become involved depending on their role.

The Turkish Advertising Board may investigate advertisements, order their suspension or correction, and impose administrative sanctions.

Misleading Performance Claims

Sports brands frequently make statements concerning:

• increased athletic performance,
• faster recovery,
• improved endurance,
• injury prevention,
• weight loss,
• muscle growth,
• better balance,
• reduced fatigue,
• or superior protection.

These claims should be supported by reliable and relevant evidence.

A statement such as “improves running speed by 20%” creates a measurable performance claim. The advertiser should possess appropriate scientific, technical, or testing evidence before publication.

General marketing expressions may also become misleading where the overall presentation gives consumers an unsupported impression. Small disclaimers may not cure a prominent and deceptive headline.

Health and Nutrition Claims

Sports nutrition, energy products, protein foods, recovery products, and similar goods require particular caution.

Brands should avoid:

• presenting ordinary foods as medical treatments,
• claiming that a product cures injuries or diseases,
• exaggerating weight-loss results,
• using unauthorized health claims,
• or suggesting guaranteed physical transformation.

Medical-looking graphics, white coats, athlete testimonials, and scientific terminology may increase regulatory risk where they create an unsupported health impression.

A disclaimer stating that results vary will not necessarily protect a campaign built around a misleading promise.

Athlete and Influencer Marketing

Professional athletes and fitness influencers can significantly affect purchasing decisions. When they receive money, products, discounts, travel, commissions, or another commercial benefit, the relationship should be clearly disclosed.

The Ministry of Trade’s guidance on social media advertising requires commercial communications by influencers to be understandable and identifiable by the target audience. The guidance also addresses the responsibilities of advertisers in influencer campaigns.

Sports brands should ensure that disclosure:

• appears prominently,
• is not hidden among hashtags,
• is understandable in the publication language,
• remains visible throughout video content,
• and accurately reflects the commercial relationship.

The brand should also provide written compliance instructions and monitor whether athletes and influencers follow them.

Testimonials and Before-and-After Content

Testimonials must reflect genuine experiences and should not create misleading expectations.

Risky practices include:

• digitally altering body images,
• using fabricated customer reviews,
• presenting paid endorsements as independent opinions,
• implying that exceptional results are typical,
• or failing to disclose material conditions.

Before-and-after photographs require additional caution because lighting, posture, clothing, editing, training history, and diet may materially affect the consumer’s impression.

Sponsorship and Ambush Marketing

A sports brand that sponsors a club, athlete, competition, or sporting event must use only the rights granted under its sponsorship agreement.

The contract should define:

• logos and trademarks that may be used,
• territories,
• media channels,
• campaign duration,
• player appearances,
• image rights,
• category exclusivity,
• and approval procedures.

A company that is not an official sponsor should avoid creating the false impression of an official commercial relationship. Unauthorized use of team colors, tournament terminology, athlete images, or protected symbols may result in trademark, unfair competition, or sponsorship disputes.

Image Rights of Athletes

A club’s permission does not always provide unrestricted authority to use the name, photograph, voice, signature, or likeness of every athlete.

Sports brands should verify whether image rights are controlled by:

• the athlete,
• the club,
• a federation,
• an agent,
• a licensing company,
• or another rights holder.

Consent should address the exact campaign, media, territory, duration, editing rights, and whether content may continue to be used after the athlete leaves the club.

Unauthorized image use may lead to removal requests, compensation claims, and reputational harm.

Comparative Advertising

Comparative advertising may be lawful under certain conditions, but comparisons must be objective, verifiable, and non-misleading.

A sports brand should not claim that its shoe, equipment, application, or service is “the best,” “the safest,” or “the fastest” unless the statement can be properly substantiated.

Comparisons should involve equivalent products and should not unfairly discredit a competitor.

Discount and Price Promotions

Campaigns using phrases such as “50% off,” “lowest price,” “final opportunity,” or “exclusive discount” must reflect genuine pricing conditions.

Potential violations include:

• increasing the price shortly before announcing a discount,
• displaying an artificial reference price,
• creating false urgency,
• failing to disclose campaign limits,
• or advertising unavailable products.

Terms relating to stock, duration, eligibility, delivery, product categories, and exclusions should be clearly disclosed.

Competitions, Giveaways, and Fan Promotions

Sports brands often organize ticket giveaways, signed-shirt campaigns, prediction contests, and social media competitions.

The rules should specify:

• eligibility,
• participation period,
• selection method,
• prize details,
• territorial limits,
• tax responsibilities,
• personal data processing,
• and disqualification grounds.

Some prize structures may require additional legal review under Turkish promotional, lottery, or regulatory rules. Brands should not launch chance-based campaigns without determining whether official authorization is necessary.

Personalized and Targeted Advertising

Digital campaigns may use browsing history, purchase behavior, location data, device identifiers, and fan preferences to personalize advertisements.

Turkey introduced further consumer-protection requirements concerning personalized pricing and targeted commercial practices in 2026. The Ministry of Trade stated that advertisers using such systems may need to provide consumers with direct and easily accessible information regarding the criteria used to display advertisements and how those criteria can be changed.

Sports brands should document:

• which data is collected,
• why it is processed,
• which legal basis applies,
• who receives it,
• how long it is retained,
• and whether it is transferred abroad.

Personal Data and Marketing Cookies

Advertising cookies, retargeting technologies, fan databases, loyalty applications, and personalized campaigns may involve processing personal data.

The Turkish Personal Data Protection Authority has confirmed in its decisions that the use of advertising and marketing cookies may constitute personal data processing.

Where consent is relied upon, it must be specific, informed, and freely given.

Purchasing a product or creating an account should not automatically require consent to unrelated advertising where the service can reasonably be provided without that consent. The Authority has emphasized that consumers should be able to continue purchasing or membership processes without being forced to approve marketing activities.

SMS, Email, and Commercial Electronic Messages

Sending promotional SMS messages, emails, or automated calls requires compliance with both commercial electronic communications rules and personal data legislation.

The Personal Data Protection Authority has expressly stated that commercial messages must comply not only with electronic communications legislation but also with personal data protection obligations because telephone numbers and similar contact information are personal data.

Brands should establish systems for:

• obtaining valid permissions where required,
• recording consent,
• processing objections,
• offering an effective opt-out mechanism,
• and ensuring that distributors and marketing agencies use lawful databases.

Buying third-party contact lists creates substantial risk. In July 2026, the Authority reminded businesses that the use of personal data obtained from third parties for advertising and marketing must be assessed separately for each specific case under the applicable legal processing conditions.

Advertising Directed at Children

Sports clothing, football products, gaming integrations, club merchandise, and athlete endorsements may attract children.

Advertisements should not exploit children’s inexperience, encourage unsafe conduct, pressure them to persuade parents, or create unrealistic social expectations.

Campaigns involving young athletes require additional care regarding consent, image rights, personal data, and safeguarding.

Advertising Agencies and Contractual Responsibility

Using an agency does not eliminate the sports brand’s responsibility.

Agreements with agencies, influencers, clubs, and distributors should include:

• compliance obligations,
• approval procedures,
• evidence requirements,
• disclosure rules,
• intellectual property warranties,
• data protection obligations,
• indemnification clauses,
• and immediate removal procedures.

The brand should maintain a written approval record for all major campaigns.

Legal Remedies and Appeal Process

Where an advertisement is challenged, a sports brand may face an Advertising Board investigation, administrative fines, suspension orders, correction requirements, consumer claims, unfair competition proceedings, intellectual property claims, or personal data sanctions.

The appropriate response may include:

1. removing or suspending the disputed advertisement;
2. preserving campaign documents and evidence;
3. reviewing scientific and commercial substantiation;
4. responding to the competent authority;
5. correcting misleading statements;
6. negotiating with affected rights holders;
7. challenging an administrative decision;
8. filing an administrative lawsuit where permitted;
9. seeking interim protection against unlawful competitor advertising;
10. pursuing compensation for trademark infringement or unfair competition.

Appeal periods can be short. The exact remedy depends on the authority issuing the decision and the legal basis of the sanction.

Frequently Asked Questions

1. Can foreign sports brands advertise directly in Turkey?

2. Must sponsored athlete posts be labelled as advertisements?

Yes. The commercial nature of the post should be clearly and prominently disclosed.

This is highly risky. The source of the data, legal basis, disclosures, consent status, and intended use must be examined carefully.

7. Can the Advertising Board stop a campaign?

Yes. It may order suspension or correction and impose administrative sanctions where violations are identified.

8. Are agencies responsible for unlawful advertisements?

Depending on their role, agencies, advertisers, media providers, influencers, and other participants may face responsibility.

Yes. Pre-publication review is particularly important for health claims, influencers, children, discounts, personal data, and athlete image rights.

Client-Focused Legal Support

Advertising compliance should be integrated into campaign planning before content is published. A preventive review can identify misleading claims, missing disclosures, image-rights problems, unlawful data processing, and contractual risks before they develop into regulatory investigations or commercial disputes.
