0212

0212 is the telephone area code assigned to the European side of Istanbul, Turkey, within the Turkish national numbering plan. It is used for landline numbers and is dialed with a trunk prefix when calling domestically and with the country code when calling from abroad.

In domestic dialing, calls to Istanbul European side numbers appear as 0 212 followed by the local number. When dialing from outside Turkey, callers use the international format +90 212 followed by the local number. The 212 code distinguishes Istanbul’s European side from the Asian side, which uses the 216 area code.

Geographically, the 212 area code covers the European part of Istanbul, including districts such as Beşiktaş, Beyoğlu, Fatih, Şişli, and Bakırköy, among others. The city of Istanbul is served by two main geographic area codes: 212 for the European side and 216 for the Asian side, reflecting the city’s bifurcated layout across Europe and Asia.

In the broader context of telecommunications, 0212 is part of the E.164 international numbering plan and is used specifically for fixed-line services within its defined region. Mobile numbers in Turkey do not use area codes in the same way and are identified by their prefixes beginning with 5.x rather than geographic codes.
