Postcodes change continually.
When a new housing estate is created, a new postcode is created. When a group of buildings are demolished, the postcode associated with them may be deleted. In some cases, postcodes are changed to meet requirements of the Royal Mail. For example, if one sorting office is busy and a neighbouring one is relatively quiet, managers at the Royal Mail can decide arbitrarily to change postcodes in order to make better use of mail sorting offices. So postcodes continually change at the detailed level but of course the vast majority remain unchanged from year to year.
