Anniversary of the Introduction of Postal codes in Spain 1.6.1987

This stamp and cover were issued on 1.6.1987 on the Anniversary of the Introduction of Postal codes in Spain. These codes were introduced and standardized in Spain in 1976, when Correos (the national postal service of Spain) introduced automated mail sorting. The first two digits (ranging 01–52) of the postal code correspond to one of the fifty provinces of Spain (as listed in general alphabetical order, with some exceptions), plus the two autonomous cities on the African coast.

Large cities such as Madrid and Barcelona, were divided into postal districts (zonas in Spanish) similar to the arrondissement system in Paris. These former postal districts were incorporated into the five-digit postal code.

Thank you Merja.
