Iso 3166-2:la

ISO 3166-2:LA is the entry for codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1.

Currently for Laos, ISO 3166-2 codes are defined for 1 prefecture, 16 provinces, and 1 special zone. The special zone Xaisômboun, which is listed, was merged back into Vientiane Province and Xiangkhouang Province in 2006.

Each code consists of two parts, separated by a hyphen. The first part is LA, the ISO 3166-1 alpha-2 code of Laos. The second part is two letters.
