We support our customers in the use of the most up to date sortation by regularly updating our databases. This revision brings about a new "Version" of the Selection Files. Please ensure the correct version of the Royal Mail Selection Files is used. 

During the lifetime of the Royal Mail Access Selection Files, it is sometimes necessary to make changes for the introduction of new Postcodes.  If new Postcodes are introduced, then a new Royal Mail Access Selection File "Release" is produced which reflects these additions. 

The launch of a new Royal Mail Access Selection Files is always "Release 1" and each new release thereafter is then numbered sequentially, until the next Version is produced.

To ensure that our customers' mail is processed and delivered to the right address as quickly and efficiently as possible, all our customers are required to use the current Version of the Royal Mail Access Selection Files to sort their postings. And it is recommended that customers use the most recent Release of the Royal Mail Access Selection Files.
