The WITHERNSEA Post Town is a Postal Region within the historic Postal County of Yorkshire
When addressing mail to properties within this area it is important to write WITHERNSEA in capital letters before the postcode.
You no longer need to write the postal county of Yorkshire when writing an address but many still do because it's fun and avoids confusion when a postal town shares the same name.
