ISO 3166-2:TR is the entry for Turkey (spelled "Türkiye") in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1.

Currently for Turkey, ISO 3166-2 codes are defined for 81 provinces.

Each code consists of two parts, separated by a hyphen. The first part is TR, the ISO 3166-1 alpha-2 code of Turkey. The second part is two digits:

• 01–67: provinces as of mid 1980s
• 68–71: provinces created in 1989
• 72–73: provinces created in 1990
• 74: province created in 1991
• 75–76: provinces created in 1994
• 77–79: provinces created in 1995
• 80: province created in 1997
• 81: province created in 1999

The digits are currently used in vehicle registration plates and postal codes. The codes 01–67 are assigned in Turkish alphabetical order, except Mersin, Kahramanmaraş and Şanlıurfa, whose codes are assigned based on their historic names, İçel, Maraş and Urfa respectively.

Current codes

Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
