# ISO 3166-2:KH

ISO 3166-2:KH is the entry for Cambodia 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 Cambodia, ISO 3166-2 codes are defined for one autonomous municipality and 24 provinces.
Each code consists of two parts, separated by a hyphen. The first part is KH, the ISO 3166-1 alpha-2 code of Cambodia. The second part is a number. The digits are currently used in postal codes, except for codes 1-9, for which one must include 0 before the number (1 becomes 01) to get the postal code from the ISO code:
* 1–21: autonomous municipalities and provinces as of late 1980s
* 22–25: autonomous municipalities and province created since the 1990s
