Common lookup mistakes

A postal code can map to more than one locality record, and the same locality name can appear in different administrative areas. Always compare the country, postal code, place name and region together before treating a match as final.

Coordinates on this page are useful for map previews and approximate area checks. They should be read as locality or postal-area centroids, not as exact delivery addresses. For bulk validation, download the country dataset and keep this canonical URL as the human-readable reference for the code.
