🇹🇷 Turkey Phone Number Format
Turkish phone numbers are 10 significant digits with a trunk 0 nationally. Mobiles start with 05 (11 digits nationally), while landlines use 3-digit area codes beginning with 02 or 03. The trunk 0 drops behind +90: 0532 123 4567 becomes +90 532 123 4567 internationally, or +905321234567 in strict E.164.

BTK, Three Mobile Carriers and Istanbul's Split Area Codes
Turkey's telecommunications is regulated by BTK (Bilgi Teknolojileri ve İletişim Kurumu). The mobile market has three major carriers: Turkcell dominates with the 0530–0539 and 0505–0508 ranges; Vodafone Turkey holds 0542–0549, 0511, and 0552–0555; Türk Telekom's mobile arm (TTNET/Türk Telekom Mobil) uses 0550–0553 and 0500–0504. Mobile numbers are all 10 significant digits (05xx + 7 digits), giving 11 digits nationally with the trunk 0.
Istanbul is unique in having two area codes — 0212 for the European side and 0216 for the Asian side — a division that dates to the Bosphorus strait separating the city into two continents. Landlines with 0212 and 0216 are both Istanbul numbers but physically on different shores. Other major cities have single codes: Ankara 0312, İzmir 0232, Bursa 0224, Antalya 0242. All landline area codes begin with 02 or 03, making them easy to distinguish from 05xx mobiles.
Turkey uses a closed numbering plan: all significant numbers (mobile and landline) are exactly 10 digits after the trunk 0. This means length-based validation is reliable once the trunk 0 is accounted for — a 10-significant-digit number starting with 5 is a mobile, one starting with 2 or 3 is a geographic landline. The E.164 form is therefore always +90 followed by exactly 10 digits.
