Data questions

How to validate postal code TW3

Treat TW3 as a text value, not a number. Postal identifiers can contain leading zeroes, spaces or letters in other countries, so applications should validate the country and original string together. For this page, the code is valid when it appears with one of the mapped localities below and the administrative path belongs to United Kingdom.

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.
