ISO 3166-2:SI

ISO 3166-2:SI is the entry for Slovenia 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 Slovenia, ISO 3166-2 codes are defined for 210 municipalities. Mirna, a municipality created in 2011, is not listed.

Each code consists of two parts, separated by a hyphen. The first part is SI, the ISO 3166-1 alpha-2 code of Slovenia. The second part is three digits, which is the municipality code used by the Statistical Office of the Republic of Slovenia:

• 001–147 (except 145): municipalities as from 1995 to 1998
• 148–193: municipalities created in 1998
• 194: municipality created in 2002
• 195–206: municipalities created in March 2006
• 206–211: municipalities created in June 2006

The codes for all groups of municipalities are assigned in Slovenian alphabetical order, except Tišina and Šalovci, whose codes are assigned based on their former names, Cankova-Tišina and Hodoš Šalovci respectively. Žalec, whose municipality code was 145, uses 190 after splitting into multiple municipalities in 1998.
