Postal codes in Spain

Two-digit prefixes

The first two digits of a Spanish postal code identify the province or autonomous city it belongs to. The numbers were assigned to the 50 provinces of Spain ordered alphabetically at the time of implementation. The official names of some of the provinces have since changed, either to the regional language version of the name (e.g. from the Spanish Guipúzcoa to the Basque Gipuzkoa) or to adopt the name of the autonomous community instead of the provincial capital (e.g. Santander to Cantabria). In these cases, the originally assigned code has been maintained, resulting in some exceptions to the alphabetical order. In addition, Ceuta and Melilla were originally included within the postal areas of Cádiz and Málaga respectively; in 1995 they were assigned their own codes and hence ended up at the end of the list.

The list below includes all 52 two-digit prefixes assigned to the 50 provinces and two autonomous cities. Included in brackets are the names of the provinces that were used for alphabetical sorting at the time of implementation, if different from the current name used in English.
