ISO 3166-2:CZ is the entry for Czechia 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, ISO 3166-2 codes are defined for two levels of subdivisions within the country:

• 13 regions and 1 capital city
• 76 districts

Each code consists of two parts, separated by a hyphen. The first part is CZ, the ISO 3166-1 alpha-2 code for the country. The second part is either of the following:

• two digits: regions
• three characters (two digits followed by a digit or a letter): districts

For the districts, the first two digits indicate the region that the district is in (based on the original NUTS code of the region):

• 10 and 11: Prague
• 20: Central Bohemian Region
• 31: South Bohemian Region
• 32: Plzeň Region
• 41: Karlovy Vary Region
• 42: Ústí nad Labem Region
• 51: Liberec Region
• 52: Hradec Králové Region
• 53: Pardubice Region
• 63: Vysočina Region
• 64: South Moravian Region
• 71: Olomouc Region
• 72: Zlín Region
• 80: Moravian-Silesian Region
