Enter a single code or paste up to 25 codes in our Validator. It verifies both the official country syntax pattern and real existence in our 1.82M+ global postal database, returning the verified city, region, coordinates and standard envelope lines.
International mailing addresses follow Universal Postal Union (UPU S42) rules: in the US, UK, Canada and Australia the postal code goes after the city/state (e.g. NEW YORK, NY 10001); in mainland Europe and Latin America it precedes the city (e.g. 28001 MADRID); and in Brazil the 8-digit CEP goes on its own line below the city-UF (01001-000).
