KVKK vs GDPR: The Differences That Actually Change Your Work
Teams that have already done GDPR often assume Turkey is a copy-paste exercise. The structures do rhyme — but four differences reliably create compliance gaps.
Note: General information, not legal advice. Verify specifics with qualified Turkish counsel.
Where they align
Both frameworks share the same architecture: data controller and data processor roles, a closed list of lawful bases, purpose limitation and data minimisation principles, data subject rights, security obligations, breach notification duties and administrative fines.
If you have a GDPR record of processing activities, you already have 70% of the raw material for a Turkish inventory.
Difference 1: Consent culture
| GDPR | KVKK | |
|---|---|---|
| Consent form | Explicit consent, one of six bases | Explicit consent, one of the lawful bases |
| Practice | Legitimate interest widely used | Practice historically leans on explicit consent, and Board decisions scrutinise its use closely |
| Bundling | Prohibited | Prohibited — and separate consent texts are the norm |
The practical consequence: in Turkey you will typically need a separate, standalone consent document rather than a checkbox embedded in your terms. Marketing communications also interact with Turkey's electronic communications rules, which have their own consent regime.
Difference 2: The public registry (VERBIS)
GDPR has no equivalent. Turkey maintains VERBIS, a publicly searchable registry where obligated controllers declare their data categories, purposes, recipients, retention periods and security measures.
Consequences for international teams:
- Your declaration is public — it should match your privacy notice exactly
- Changes must be updated within 30 days
- Foreign controllers subject to registration may need a representative in Turkey
Details: VERBIS registration for foreign companies.
Difference 3: Cross-border transfers
Both regimes restrict transfers abroad, but the mechanics differ. Turkey's framework provides for adequacy decisions, appropriate safeguards including standard contractual clauses, and specific derogations — with notification steps attached to some routes.
What this means in practice: your EU SCC package does not automatically satisfy Turkish requirements. If your Turkish entity uses non-Turkish cloud, email or CRM infrastructure, treat transfer documentation as separate work.
Difference 4: Data subject rights and timelines
The catalogue of rights is similar — access, rectification, erasure, objection to automated decisions, compensation for damage. The mechanics differ in ways worth noting:
- Turkish practice expects a response within 30 days
- Data subjects generally must apply to the controller first, before escalating to the Board
- Certain applications have formal requirements that a purely email-based process may not satisfy
Practical mapping exercise
If you're extending an existing GDPR programme to Turkey, do this in order:
- Filter your RoPA to processes touching individuals in Turkey
- Re-test each lawful basis against Article 5 — do not assume legitimate interest carries over
- Split out consent-based processing into standalone consent texts
- Re-document transfers under the Turkish regime
- Assess VERBIS obligation and register if in scope
- Localise the privacy notice into Turkish
- Have Turkish counsel review the package

FAQ
Can we run one global privacy notice?
You can keep a global master, but you will need a Turkey-specific version reflecting Turkish lawful bases, the local contact point and Turkish language.
Does a DPO satisfy Turkish requirements?
KVKK does not mirror GDPR's DPO institution. It uses a contact person for VERBIS purposes, which is a different role with different responsibilities. Your DPO may fill it in practice, but the appointment is separate.
Are the fines comparable?
The fine ranges are set in Turkish law and adjusted annually; they are not tied to global turnover the way GDPR's upper tier is. That makes them lower in absolute terms for large multinationals — but reputational and operational consequences still apply.
Which comes first if we're doing both?
Do GDPR first if you're starting from zero — its documentation discipline transfers well. Then run the Turkey mapping exercise above rather than assuming coverage.
