## Postcode Verification

Postcodes cannot be validated just with a regular expression. Proper postcode validation requires having a full list of postcodes to check against. Relying on a regex will produce false postives/negatives.

A complete list of Postcodes can be obtained from the ONS Postcode Directory, which is updated every 3 months.
Postcodes can only be validated using pattern matching, such as regular expressions. Accurate postcode verification would require having a full list of postcodes to check against.
