KVKK Compliance Guide: Turkey’s Data Protection Law for Foreign Investors
If you’re establishing a business in Turkey, understanding the country’s data protection framework isn’t optional - it’s essential. The Law on the Protection of Personal Data (KVKK - Kişisel Verilerin Korunması Kanunu), Law No. 6698, came into force in April 2016 and represents Turkey’s comprehensive approach to data privacy. Often compared to the EU’s GDPR, KVKK establishes strict rules for how businesses collect, process, store, and transfer personal data.
For foreign investors, KVKK compliance is a critical consideration from day one of operations in Turkey.
What is KVKK?
KVKK is Turkey’s primary data protection legislation, modeled after the EU Data Protection Directive (95/46/EC) and sharing many similarities with GDPR. The law applies to:
- All natural and legal persons who process personal data
- Both automatic and non-automatic data processing (if part of a filing system)
- Data processing activities within Turkey
- Processing of Turkish citizens’ data regardless of where the processing occurs
The Personal Data Protection Authority (KVKK Kurumu) oversees enforcement, issues regulations, and maintains the Data Controllers Registry (VERBİS).
Key Definitions You Need to Know
| Term | Definition |
|---|---|
| Personal Data | Any information relating to an identified or identifiable natural person |
| Special Categories of Data | Race, ethnicity, political opinions, religious beliefs, health data, biometric data, criminal records, etc. |
| Data Controller | The natural or legal person who determines the purposes and means of processing |
| Data Processor | The natural or legal person who processes data on behalf of the controller |
| Explicit Consent | Freely given, specific, informed consent based on clear information |
| VERBİS | Data Controllers Registry - mandatory registration system |
Who Must Comply with KVKK?
All entities processing personal data in Turkey must comply with KVKK. This includes:
- Turkish companies (LLC, Joint Stock, branches)
- Foreign companies with Turkish operations
- Companies processing data of individuals in Turkey
- Organizations employing staff in Turkey
- E-commerce businesses serving Turkish customers
VERBİS Registration Requirements
Not all data controllers must register with VERBİS, but most businesses will need to. Registration is mandatory for:
- Companies with 50+ employees
- Companies with annual turnover exceeding 25 million TRY
- Companies whose main activity involves processing special categories of data
- Companies whose main activity involves processing data for profiling or marketing
Registration exemption applies to:
- Companies with fewer than 50 employees AND less than 25 million TRY annual turnover (subject to conditions)
- Certain public institutions
- Notaries and lawyers (under specific conditions)
Even if exempt from VERBİS registration, you must still comply with all other KVKK provisions.
The Six Core Principles of Data Processing
Under KVKK Article 4, personal data must be processed in accordance with these principles:
1. Lawfulness and Fairness
Data processing must have a legal basis and must not violate the data subject’s rights or legitimate expectations.
2. Accuracy and Currency
Personal data must be accurate, complete, and up-to-date. Organizations must establish mechanisms for data subjects to correct their information.
3. Purpose Limitation
Data must be collected for specified, explicit, and legitimate purposes. Processing beyond these purposes requires new consent or legal basis.
4. Data Minimization
Only data that is necessary for the specified purpose should be collected - no excessive data gathering.
5. Storage Limitation
Personal data must not be kept longer than necessary for the purposes for which it was collected.
6. Security
Appropriate technical and organizational measures must be implemented to protect data against unauthorized access, loss, or damage.
Legal Bases for Processing Personal Data
Unlike collecting stamps, you can’t just collect personal data because you want to. You need a legal basis. KVKK Article 5 provides the following:
For Regular Personal Data:
- Explicit consent of the data subject
- Explicit legal provision - processing required by law
- Protection of life - when the data subject is physically or legally incapable of giving consent
- Contract performance - necessary for entering into or performing a contract
- Legal obligation - necessary for the controller to fulfill legal obligations
- Public disclosure - data made public by the data subject
- Legal claims - necessary for establishing, exercising, or defending legal claims
- Legitimate interests - necessary for legitimate interests of the controller (provided it doesn’t override fundamental rights)
For Special Categories of Data (Article 6):
Processing is generally prohibited unless:
- Explicit consent is obtained, OR
- Specific legal provisions apply (e.g., health data processed by healthcare professionals)
Data Subject Rights Under KVKK
Individuals have significant rights regarding their personal data. Your business must be prepared to respond to requests exercising these rights within 30 days:
- Right to know whether personal data is being processed
- Right to access personal data and request information about processing
- Right to know the purpose of processing and whether data is used accordingly
- Right to know third parties to whom data is transferred
- Right to request correction of incomplete or inaccurate data
- Right to erasure under conditions specified in Article 7
- Right to object to processing results obtained through automated systems
- Right to compensation for damages resulting from unlawful processing
Data Transfer Rules
Domestic Transfers
Transfer of personal data within Turkey requires:
- Informing the data subject
- Having a lawful basis for processing (same as collection)
- Ensuring the recipient maintains adequate security measures
International Transfers
Cross-border data transfers are heavily regulated under KVKK. Transfer is permitted when:
- Explicit consent is obtained from the data subject, OR
- One of the Article 5/6 processing conditions is met AND either:
- The destination country is on the “safe countries” list (determined by the Board), OR
- The data controllers in Turkey and abroad provide adequate protection through binding commitments approved by the Board
Important: As of 2026, the KVKK Board has approved very few countries as providing adequate protection. Most international transfers require additional safeguards, such as:
- Binding Corporate Rules (BCR)
- Standard Contractual Clauses approved by the Board
- Case-by-case Board approval
This is particularly relevant for foreign investors who need to transfer employee or customer data to headquarters abroad.
VERBİS Registration Process
If your company must register with VERBİS, here’s the process:
Step 1: Appoint a Contact Person
Designate an individual responsible for communication with the KVKK Authority.
Step 2: Complete Data Inventory
Document all personal data processing activities, including:
- Categories of data processed
- Purposes of processing
- Data retention periods
- Security measures
- Transfer destinations
Step 3: Online Registration
Access the VERBİS portal and complete the registration form with:
- Company information
- Contact person details
- Processing categories and purposes
- Retention periods
- Security measures
Step 4: Maintain Records
Keep your VERBİS registration updated. Any significant changes must be reported within 7 days.

- Notify affected data subjects - if the breach is likely to result in high risk
- Document the breach - including facts, effects, and remedial measures
Your breach notification to the Authority must include:
- Description of the breach
- Categories and approximate number of affected individuals
- Categories and approximate number of affected records
- Contact details of the data protection officer
- Likely consequences
- Measures taken or proposed
Practical Tips for Foreign Investors
1. Start Early
Begin KVKK compliance planning before you start operations in Turkey. Retrofitting compliance is more expensive and disruptive.
2. Conduct a Data Mapping Exercise
Understand what personal data you’ll collect, why, where it will flow, and how long you’ll keep it. This forms the foundation of your compliance program.
3. Localize Your Approach
While KVKK resembles GDPR, differences exist. Don’t assume your EU compliance program directly transfers. Key differences include:
- Different explicit consent requirements
- Stricter international transfer rules
- VERBİS registration system unique to Turkey
- Different enforcement culture and precedents
4. Turkish Language Requirements
Privacy notices and consent forms must be in Turkish. Ensure professional translation by someone who understands legal terminology.
5. Plan International Transfers Carefully
If your business model requires transferring data outside Turkey (to headquarters, cloud providers, etc.), build your transfer mechanism early. Options include:
- Seeking explicit consent (burdensome for ongoing transfers)
- Binding Corporate Rules (time-consuming approval process)
- Keeping data localized in Turkey where possible
6. Budget for Compliance
Factor KVKK compliance costs into your business plan:
- Legal consultation fees
- Technical security implementations
- Training programs
- Potential local data storage requirements
- Ongoing compliance monitoring
