AND ALSO :
UK Post Code parsing pattern:
^(? (?:[ABD-HJLNP-UW-Z]{1,2})(?:(?:\d{1,2})|(?:\d[ABD-HJLNP-UW-Z])))\s*(? \d[ABD-HJLNP-UW-Z]{2})$
Captures the first section of the post code to the named group "OutCode" and the second section of the post code to the named group "InCode".
UK Post Code validation pattern:
^(?:[ABD-HJLNP-UW-Z]{1,2})(?:(?:\d{1,2})|(?:\d[ABD-HJLNP-UW-Z]))\s*\d[ABD-HJLNP-UW-Z]{2}$
Valid UK postal codes follow the below patterns:
A9 9AA A99 9AA A9A 9AA AA9 9AA AA99 9AA AA9A 9AA
