Can International Businesses Store Turkish Customer Data Abroad under KVKK?

For international companies expanding into Turkiye, data localization is often one of the most challenging operational hurdles. Global enterprises typically rely on centralized cloud infrastructure, meaning customer, user, or employee data collected locally is automatically transferred to data centers in Europe, the US, or other regions.

However, under Turkiye’s Personal Data Protection Law (KVKK), cross-border data transfer is not a matter of technical convenience. It is a strict legal process. Following recent regulatory overhauls and the full implementation of digital filing systems, the rules governing international data flows have entered a brand new era. If your business stores Turkish data abroad, understanding this updated legal landscape is critical to avoiding major regulatory fines.

1. The Paradigm Shift: Explicit Consent Is Now the Exception

Historically, companies operating in Turkiye heavily relied on obtaining explicit consent from users as a blanket solution for international data transfers. However, recent amendments have completely flipped this framework. Explicit consent is no longer the primary mechanism. It has been downgraded to an exceptional, secondary resort.

Relying solely on consent is operationally unstable and legally fragile because users maintain the absolute right to withdraw it at any time, instantly disrupting global data flows. Instead, the Turkish Data Protection Authority (KVKK Kurumu) now demands that global enterprises ground their cross-border transfers in appropriate safeguards whenever data processing relies on statutory grounds, such as the performance of a contract or legitimate interests.

2. Appropriate Safeguards for Continuous Transfers

For multinational companies that routinely, continuously, or systematically transfer personal data from Turkiye to foreign parent companies or third party vendors, the law provides three structured pathways under the umbrella of appropriate safeguards.

• Adequacy Decisions: The Board can determine that a specific country, sector, or international organization ensures an adequate level of protection. Data can flow to these recognized destinations without additional administrative permits.
• Standard Contractual Clauses (SCCs): This is currently the most practical and widely utilized tool for global enterprises. Data controllers and processors must execute standard contracts prepared by the Authority. Crucially, these executed SCCs are not just internal documents. They must be formally notified to the Board within strict statutory deadlines through official digital notification systems.
• Binding Corporate Rules (BCRs): Tailored specifically for multinational group companies, BCRs allow intra group data sharing globally, provided the overarching corporate data policy is formally reviewed and approved by the Turkish Data Protection Board.

3. The Exception: What Qualifies as an Incidental Transfer?

A highly critical distinction clarified by recent official guidelines is the concept of incidental transfers. If a data transfer between a Turkish entity and an international party occurs only once, or a few times, is non continuous, irregular, and does not form a part of the regular, systemic course of business, it may bypass the stringent requirement for continuous safeguards like SCCs.

Examples include a one off cross border payment processing or an isolated customer request fulfillment. However, global businesses must be cautious. If the transfer happens routinely as part of your business model, it is continuous, and appropriate safeguards become mandatory.

4. What Happens If You Violate the Rules?

The Turkish Data Protection Authority actively monitors global technology platforms, e-commerce entities, and hospitality businesses. Illegally transferring data abroad or failing to properly notify executed Standard Contractual Clauses to the Board carries severe financial risks.

Administrative fines are adjusted annually with heavy non compliance penalties that can easily reach millions of Turkish Liras per violation, alongside severe reputational damage in the local market.

5. Action Steps for Global Companies

If your enterprise infrastructure relies on global servers, your compliance strategy must adapt to the proactive enforcement standards. International businesses operating in Turkiye should immediately take these steps:

1. Audit and Map Data Flows: Identify exactly where Turkish user and employee data is hosted, distinguishing between continuous and incidental transfers.
2. Transition Away from Consent: Shift your legal basis to appropriate safeguards if your data transfers are continuous and systematic.
3. Execute and Notify SCCs: Implement the Authority's Standard Contractual Clauses with global vendors or parent entities, and ensure they are formally filed with the Board within the legal timeframe.

Ensuring compliance protects your enterprise from regulatory penalties and builds trust with your local Turkish customer base.
