Data Protection Authority (Kişisel Verileri Koruma Kurumu)

Anticipated changes to law

The declaration of the list of countries where an adequate level of protection with regards to Data Protection by the Data Protection Authority is to be anticipated.

If applicable: stage of legislative implementation of GDPR

As a non-EU member state, Turkey is not implementing GDPR. However, the companies processing the personal data are required to become compliant with the Law and its regulations within two years following the effective date of the Law, which was 7th April 2018.

If applicable: local derogations as permitted by GDPR 

As a non-EU member state, Turkey is not implementing GDPR. However, the Law regulates certain exceptions to its own application:

  • Article 5/2 of the Law sets forth the cases where the personal data may be processed without obtaining the explicit consent of the data subject (i.e. (a) it is expressly permitted by any law; (b) it is necessary in order to protect the life or physical integrity of the data subject or another person where the data subject is physically or legally incapable of giving consent; (c) it is necessary to process the personal data of parties of a contract, provided that the processing is directly related to the execution or performance of the contract; (d) it is necessary  for compliance with a legal obligation which the controller is subject to; (e) the relevant information is revealed to the public by the data subject herself/himself; (f) it is necessary for the institution, usage, or protection of a right and (g) it is necessary for the legitimate interests of the data controller, if the fundamental rights and freedoms of the data subject are not harmed).
  • As per Article 6/3 the Law, sensitive data, other than those relating to health and sexual life, may be processed without seeking explicit consent of the data subject in the cases required by laws. Personal data relating to health and sexual life may only be processed, without seeking explicit consent of the data subject, by persons and authorised public institutions and organizations that have confidentiality obligation, for the purpose of the protection of public health, operation of preventive medicine, medical diagnosis, treatment and nursing services, planning and management of health care services and their financing.
  • The Law shall not be applied in the following cases:
    • Processing by data subject in the context of purely personal activities of him/her or of family members living together with him in the same dwelling provided that it is not disclosed to third parties and data security obligations are complied with.
    • Processing for the official statistical and planning purposes after anonymization.
    • Processing for artistic, historical, literary, and scientific purposes or within the scope of freedom of expression without violating national defence, national security, public security, public order, economic security, right to privacy or personal rights or without constituting a crime.
    • Processing within the scope of preventive, protective and intelligence activities carried out by authorised public institutions and organizations
    • Processing by judicial/execution authorities in the context of investigation, prosecution, criminal and execution proceedings


The Law has introduced principles of data protection in Turkey that are in line with compatible principles of European Union regulations. The Law aims to protect fundamental rights of individuals, particularly the right to privacy, with respect to processing of personal data and to set forth obligations, principles and procedures which shall be binding upon individuals or legal entities who process personal data. 

The provisions of the Law shall apply to individuals whose personal data are processed as well as to individuals or legal entities who process such data wholly or partially through automatic means or through otherwise than automatic means, provided that the process is a part of any data registry system.


The Data Protection Authority has the enforcement powers concerning administrative sanctions only. The potential administrative sanctions are (i) administrative fines up to TL 1.000.000 and (ii) suspension of the processing the data and transferring the same abroad. 

If the failure is committed within the public institutions or organizations as well as the professional organisations having the status of public institution, disciplinary procedures shall be imposed on such officers and public officials. 

If the failure constitutes a crime as per Articles 135 to 140 of the Turkish Penal Code, the criminal sanction, including imprisonments and sanctions applicable to legal entities (i.e. cancellation of activity permits, confiscation of the assets and income of the legal entity), will be imposed by the court.

Registration / notification 

Data Controllers must register with the Data Controller Registry (VERBIS) within 30 (thirty) days*, starting from the date that the data controller becomes liable to register, as per Article 8 of the Regulation on the Data Controller Registry (Certain exceptions are applicable).

* As the Data Controller Registry (VERBIS) has become active by 2nd of October 2018, the Data Protection Authority has decided to provide a transition period for the Data Controllers to register with the Data Controller Registry (VERBIS). The deadline for (i) the Data Controllers which employ at least 50 employee or have at least an annual balance sheet of TL 25 million (c. Euro 3.5 million) or (ii) the data controllers residing abroad to enrol in VERBIS is 30 September 2019. (Other deadlines are applicable to certain Data Controllers which do not fall in the above scope).

Processing by third parties

The Law requires express consent from data subjects for transfers to third parties. (Certain exceptions are applicable)

Transfers out of Country

Personal data cannot be transferred outside of Turkey without the explicit consent of the data subject. 

In the following cases, personal data may be transferred outside Turkey without the explicit consent of the data subject:

  • The foreign country to which personal data will be transferred to has to have an adequate level of protection,
  • Where the adequate level of protection does not exist, the data controllers in Turkey and in related foreign country commit, in writing, to provide an adequate level of protection and the Authority has authorised such transfer.

*The countries where an adequate level of protection exist shall be (but have not been to date) declared by the Data Protection Authority.


The data controllers are required to take all necessary technical and organizational measures to provide an appropriate level of security in order to

  • prevent the unlawful processing of personal data,
  • prevent the unlawful access to personal data,
  • safeguard personal data.

In instances where personal data is processed on behalf of the data controller by another natural or legal person, the data controller shall be jointly liable with such persons with regard to taking the measures set forth in the first paragraph.
