What is BTK?
The Bilgi Teknolojileri ve İletişim Kurumu (BTK) is Türkiye’s independent telecommunications and information technologies regulator, established under 5809 sayılı Elektronik Haberleşme Kanunu. BTK licenses operators, manages spectrum, regulates internet hosting and access providers under 5651 sayılı Kanun, runs the Türkiye Internet Records (TIB-successor functions), and supervises consumer rights in electronic communications. BTK also operates URL blocking and content takedown enforcement.
Core competencies
- Spectrum and licensing: mobile, fixed-line, satellite, broadcast.
- Internet regulation (5651): hosting providers, access providers, content providers, social network providers (Madde 5/A added 2020).
- Consumer protection: Mobile Number Portability, billing transparency, dispute resolution.
- Cybersecurity: USOM (National Cyber Incident Response Centre) coordinates incident response.
- Social network provider regime: platforms with >1 million daily Turkish users must appoint a local representative, store local user data in Türkiye, and respond to court orders within 48 hours.
Recent enforcement
BTK has issued multi-million-TRY administrative fines to global platforms for failing to appoint local representatives or remove content within statutory deadlines. Bandwidth throttling and access blocking are escalating enforcement tools used in conjunction with monetary fines.
For startups and platforms
Crossing the social-network user threshold triggers significant compliance obligations. Hosting providers and access providers must maintain valid BTK registrations and respond to URL blocking requests promptly to avoid joint liability.
Do: register with BTK if you operate hosting or access services; appoint a representative early as user base approaches the threshold.
Don’t: rely on “we use offshore hosting” — 5651 obligations attach based on Turkish user nexus, not server location.
