In Turkiye, provinces and metropolitan municipalities both sit at administrative level 2 but serve different functions. Provinces (i̇ller) — there are 54 — typically group multiple smaller municipalities under a shared administration. Metropolitan municipalities (büyükşehir belediyeler) — there are 27 — are a larger city or urban area that handle its own administration independently.

Turkish administrative divisions have specific local names at each level. In Turkish, regions are called Coğrafi bölgeleri; provinces are called İller; metropolitan municipalities are called Büyükşehir Belediyeler; districts are called İlçeler; metropolitan district municipalities are called Büyükşehir İlçe Belediyeler; metropolitan town municipalities are called Büyükşehir Beldeler; district municipalities are called İlçe Belediyeler; town municipalities are called Belde Belediyeler; provincial municipalities are called İl Belediyeler; villages are called Köyler; municipal neigbourhoods are called Belediye Mahalleler; metropolitan neighbourhoods are called Büyükşehir Mahalleler; towns are called Beldeler; village neighbourhoods are called Köy Mahalleler. These local-language terms appear in official documents, legal records, and government databases, so matching them correctly is important for data integration and compliance.

Administrative boundaries in Turkiye change as governments reorganize regions, merge municipalities, or create new administrative units to reflect population shifts and political decisions. Changes most commonly affect the village neighbourhoods level, where Turkiye currently has 29,706 units. Businesses that rely on Turkish administrative data should use a regularly updated reference dataset to avoid mismatches in geocoding, tax jurisdiction mapping, and compliance reporting.
