UK Postcode validation and location

Geo::Postcode will accept full or partial UK postcodes, validate them against the official spec, separate them into their significant parts, translate them into map references or co-ordinates and calculate distances between them.

The last two features require a postcode database to be supplied separately.

It does not check whether the supplied postcode exists: only whether it is well-formed according to British Standard 7666, which you can find here:

Geo::Postcode will also work with partial codes, ie areas, districts and sectors. They won't validate, but you can test them for legitimacy with a call to valid_fragment, and you can still turn them into grid references.

To work with US zipcodes, you need Geo::Postalcode instead.
