A Turkish driving licence has to be renewed once the validity date printed on it passes, once the card becomes unreadable, or if it is lost. The transaction is handled at district civil registry offices and runs on appointments, so the real work is preparing the right documents in advance and finding a free slot.
The steps below follow the official pages of the General Directorate of Civil Registration and Nationality (NVİ) and the description of the e-Devlet appointment service. Fees change every year, so we give no figures here: check the current amount on the NVİ site before you pay.
