ISO 3166-2:SE is the entry forSweden inISO 3166-2, part of theISO 3166standard published by theInternational Organization for Standardization (ISO), which definescodes for the names of the principalsubdivisions (e.g.,provinces orstates) of allcountries coded inISO 3166-1.
Currently for Sweden, ISO 3166-2 codes are defined for21 counties.
Each code consists of two parts, separated by a hyphen. The first part isSE, theISO 3166-1 alpha-2 code of Sweden. The second part is one or two letters, which is the alphabetic code (Swedish:länsbokstav) of the county, and was used invehicle registration plates until 1973.
Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
In ISO 3166-2, the numeric code (länskod) of each county is shown for information purposes in square brackets after the name of the county. However, these alternative code elements are not official ISO 3166-2 codes, since this part of ISO 3166 does not allow for duplicate coding of identical subdivisions.
Subdivision names are sorted inSwedish alphabetical order: a–z, å, ä, ö.
