The Law on the Protection of Personal Data No. 6698 (KVKK) under Turkish Law sets binding compliance obligations for natural and legal persons processing personal data, aiming to safeguard fundamental rights and freedoms, particularly the privacy of personal life in both private and public sectors.

I. Core Statutory Definitions

  • Personal Data: Any information relating to an identified or identifiable natural person (Name, Turkish ID number, email, social media profiles, address, phone, purchase history, CCTV footage, IP address, employment application forms, etc.).
  • Special Categories of Personal Data (Sensitive Data): Data that may cause discrimination or victimization if exposed (Race, ethnic origin, political opinions, philosophical beliefs, religion, sect or other beliefs, clothing habits, membership in associations/foundations/unions, health, sex life, criminal convictions and security measures, as well as biometric and genetic data).
  • Data Controller: Real or legal persons who determine the purposes and means of processing personal data and are responsible for establishing and managing the data filing system (Corporate entities hold the status of Data Controller in their own right).
  • Data Processor: The real or legal person processing personal data on behalf of the data controller based on authorization.
  • VERBİS: The Data Controllers' Registry Information System operated by the Turkish Data Protection Authority.

II. Scope of Applicability for Commercial Entities

If an entity processes personal data through fully or partially automated means, or non-automated means provided that the data forms part of a structured filing system under Turkish Law, mandatory compliance with statutory provisions is required.

III. Statutory Sanctions and Penalties

1. Criminal Offenses Under the Turkish Penal Code (TPC)

Illicit processing of personal data triggers prison sentences prescribed under Articles 135 to 140 of the Turkish Penal Code No. 5237:

  • Unlawful Recording of Personal Data (TPC Art. 135/1): Imprisonment from 1 year to 3 years.
  • Recording Special Categories of Data (TPC Art. 135/2): Sentence increased by half (Imprisonment from 1.5 years to 4.5 years).
  • Unlawful Dissemination, Transfer, or Capture of Data (TPC Art. 136/1): Imprisonment from 2 years to 4 years.
  • Failure to Erase or Anonymize Data (TPC Art. 138): Failure to erase or anonymize data upon expiration of statutory retention periods carries imprisonment from 1 year to 2 years.

If these offenses are committed by public servants or by exploiting the convenience of a specific profession, penalties are increased by half (TPC Art. 137).

2. Misdemeanors and Administrative Fines (KVKK Art. 18)

Failure to meet statutory obligations results in administrative fines imposed by the Personal Data Protection Board, adjusted annually under revaluation rates, reaching millions of TRY:

  • Breach of the obligation to inform data subjects,
  • Failure to fulfill data security requirements (technical and organizational measures),
  • Failure to execute decisions issued by the Board,
  • Violation of VERBİS registration and notification obligations.

Under Turkish Law, judicial appeal against administrative fines and decisions issued by the Board lies before the Administrative Courts.

IV. Mandatory Corporate Compliance Roadmap

To establish a legally compliant data processing framework under Turkish Law, organizations must execute the following structured compliance steps:

  • Gap Analysis & Data Inventory: Mapping all personal data collected, processing purposes, retention periods, third-party transfers, and technical security protocols.
  • VERBİS Registration: Preparing a comprehensive Personal Data Inventory and completing registration with VERBİS for entities meeting statutory thresholds.
  • Privacy Notices & Explicit Consent: Drafting statutory information notices for customers, employees, and suppliers; structuring explicit consent mechanisms where required by law.
  • Policy & Contractual Revisions: Updating employment contracts, non-disclosure agreements, vendor contracts, data retention, and destruction policies.
  • Technical & Organizational Security: Enhancing cybersecurity infrastructure, establishing access control matrices, and delivering mandatory data protection training to staff.
