ISO 3166-2:NA is the entry for Namibia 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 Namibia, ISO 3166-2 codes are defined for 14 regions.
Each code consists of two parts, separated by a hyphen. The first part is NA, the ISO 3166-1 alpha-2 code of Namibia. The second part is two letters.
The Kavango East and Kavango West regions were created in August 2013 by a split of Kavango Region (which was named Okavango before 1998). At the same time, Caprivi and Karas were renamed Zambezi and ǁKaras, respectively. However, the code for the Zambezi Region was not changed, and is still derived from the former name.
