The General Data Protection Regulation (GDPR) has reshaped how personal data is collected, processed, and stored across the world. While the GDPR is an EU regulation, its influence extends well beyond the European Union’s borders, including Türkiye, due to its economic ties, digital trade, and growing role in the global market.
Türkiye has its own data protection framework—the Law on the Protection of Personal Data (KVKK)—which shares many similarities with the GDPR. However, there are also critical differences that businesses and individuals need to understand.
This article covers GDPR applicability in Türkiye, individual rights and implementation considerations.
The GDPR, enforced since May 25, 2018. Its territorial scope is defined by Article 3; EU citizenship alone does not determine whether it applies.
A Turkish business should assess its EU establishments and whether it offers goods or services to, or monitors the behavior of, people in the EU.
Turkiye’s KVKK, enacted in 2016, drew on the earlier EU Data Protection Directive 95/46/EC. GDPR and KVKK must be assessed separately.
Before 2016, Türkiye lacked a comprehensive data protection framework. The KVKK was introduced to fill this gap, ensuring that personal data was collected and processed in a lawful, transparent, and secure manner.
When reviewing KVKK amendments , identify the affected articles and effective dates before updating controls.
While GDPR and KVKK share common principles, there are notable differences.
Both GDPR and KVKK recognize consent, contractual necessity, and legal obligations as bases for processing. However, GDPR offers more detailed provisions on legitimate interest and vital interests.
The next sections cover processing principles and organizational duties .
Like the GDPR, the KVKK in Türkiye rests on a set of core principles that govern the handling of personal data. These principles ensure fairness, accountability, and protection of individual rights.
Organizations in Turkiye must process personal data lawfully and transparently. Identify the applicable processing condition and provide the required information. Where consent is used, it must meet the relevant legal standard.
Data must only be collected for a specific purpose and not reused for unrelated activities. Businesses must also adopt a data minimization approach, collecting only what is strictly necessary.
Under GDPR in Türkiye, companies are required to ensure data is accurate, up to date, and stored securely. Keeping unnecessary data for longer than needed is strictly prohibited.
GDPR grants individuals enhanced control over their data, and these rights also influence KVKK practices in Türkiye.
Individuals can request access to their personal data and demand corrections if information is inaccurate.
Individuals can request erasure when the applicable legal conditions are met; withdrawal of consent does not override every other lawful retention ground.
One of GDPR’s unique features is data portability, which allows individuals to transfer their data from one provider to another. KVKK does not yet fully replicate this right.
Where GDPR applies, its objection and restriction rights may cover marketing or profiling . Assess these separately from the rights available under KVKK.
Determine which processing activities fall under each law and document the corresponding duties.
Where GDPR applies, assess the mandatory DPO criteria in Article 37. KVKK does not create the same general DPO regime; distinguish a DPO from a Turkish data controller representative or VERBİS contact person.
Businesses must maintain compliance records, documenting how they process and safeguard data.
For a notifiable GDPR breach, notify the authority without undue delay and, where feasible, within 72 hours of awareness. Under KVKK Decision 2019/10, the controller must report an Article 12(5) breach without delay and no later than 72 hours after awareness. Assess each notification threshold separately.
Some international processing activities require dual compliance . Document why each law applies.
Transferring personal data from Turkiye to the EU, or vice versa, requires adequate safeguards such as standard contractual clauses or binding corporate rules.
EU companies with operations in Turkiye must comply with KVKK in addition to GDPR, creating an additional layer of legal responsibility.
Failure to comply with GDPR or KVKK can result in serious consequences.
Turkish authorities have imposed fines on companies for unauthorized data collection, poor cybersecurity measures, and failing to obtain explicit consent.
Banks must ensure customer data is processed transparently and securely, especially in areas like digital banking and fintech.
Sensitive health data requires higher levels of protection, and breaches can result in severe penalties.
With the rapid growth of e-commerce in Türkiye, compliance with GDPR and KVKK is essential for building consumer trust.
Employees must be trained in GDPR principles, especially those handling customer data.
Tools like data encryption, access controls, and consent management systems can help companies maintain compliance.
Documented controls can support customer assurance and data security.
Track official publications for amendments to KVKK and assess their effects on your processing activities.
Cross-border clients may ask for evidence of applicable privacy controls and transfer arrangements.
1. Does GDPR apply in Türkiye?
It can. Assess the establishment and targeting criteria in Article 3, as explained above; nationality alone does not decide the scope.
2. What is the difference between GDPR and KVKK?
GDPR is an EU regulation, while KVKK is Turkiye’s local data protection law. GDPR offers broader rights, such as data portability, compared to KVKK.
3. Do all businesses in Türkiye need a Data Protection Officer (DPO)?
No. Where GDPR applies, Article 37 determines when appointment is mandatory; large-scale sensitive-data processing can trigger that duty.
4. What are the penalties for non-compliance in Türkiye?
Fines under KVKK can reach millions of lira, while GDPR fines can be up to €20 million or 4% of annual turnover.
5. How can Turkish companies prepare for GDPR compliance?
By conducting audits, updating privacy policies, training employees, and investing in compliance technology.
6. Which sectors are most affected by GDPR in Türkiye?
Sector labels alone do not determine GDPR scope. Assess the activities, data and links to the EU.
Assess GDPR in Türkiye by documenting the territorial scope of each processing activity. Where both apply, map the duties under GDPR and KVKK separately.
Identify the processing activities within scope, document the required controls and track unresolved gaps.
