The county name is no longer required in the address if the post town and postcode are provided.

The postcode will be in one of the six following formats. 'A' represents a letter of the alphabet and 'N' a digit:

Format Example
AN NAA M2 5BQ
ANN NAA M34 4AB

There is only one exception to these formats: GIR 0AA.

The postcode must be written in capitals on the last (domestic) or penultimate (international) line of the address. It should appear on its own on a separate line, should not be underlined and should contain no punctuation. A one-character space should separate the two parts of the postcode.
