Spanish Postal Codes Format
Spanish postal codes were introduced and standardized in 1976, when the national postal service of Spain (Correos) introduced automated mail sorting.
Spanish postal code consists of 5 digits.
The first two digits (ranging 01-52) of Spanish postal code correspond a province of Spain.
Formerly large cities (e.g. Madrid and Barcelona) were divided into postal districts.
Nowadays they are incorporated into the five-digit postal code.
Some Spanish postal codes are reserved for special use at the province capital:
- 070 for official use by Correos;
- 071 to address state agencies at the given province;
- 080 for P.O. boxes and mail lists.
