Turkey is divided into 81 provinces. From 01 to 67, the numbering is arranged alphabetically throughout. In addition, there are irregularities in the alphabetical order by changing the name of the province: 33 - Mersin (until 2002 İçel) and 63-Şanlıurfa (until 1984 Urfa). Later added provinces became identification numbers from 68 to 81.
