October 2025 – In September 2025, the Turkish Personal Data Protection Authority (the "DPA") issued one decision, organised several events, and announced one data breach notification. Below is a summary of key developments.

New Exemption Criteria for VERBIS Registration

On 4 September 2025, the DPA published Decision No. 2025/1572 (the "Decision"), introducing a new exemption from the requirement to register with the Data Controllers' Registry ("VERBIS").

Under this Decision, data controllers whose main activity involves processing sensitive (special category) personal data are exempt from VERBIS registration if they employ fewer than 10 people and have an annual balance sheet total below TRY 10 million (approx. EUR 200,000).

This exemption primarily benefits small-scale healthcare providers, such as pharmacies, medical and dental clinics that meet the above thresholds. Such data controllers may also deregister from VERBIS if already registered.

Importantly, this exemption does not relieve data controllers of other obligations under Personal Data Protection Law No. 6698 ("DP Law"). Obligations such as informing data subjects, ensuring data security, and responding to data subjects' requests continue to apply.

The existing VERBIS registration thresholds remain unchanged. Currently, the following data controllers are obliged to register with VERBIS:

  • Data controllers whose main activity does not involve the processing of special categories of personal data, if they:

– employ more than 50 employees; or

– have an annual financial balance sheet total exceeds TRY 100 million (approx. EUR 2 million).

  • Data controllers whose main activity involves the processing of special categories of personal data, if they:

– employ more than 10 employees; or

– have an annual financial balance sheet total exceeds TRY 10 million (approx. EUR 200,000);

  • Data controllers located abroad;
  • Data controllers that qualify as public institutions or organisations.
