The re-allocation of Postcode Sectors to Zones requires a new release of the current version of the Access Selection Files. Release 27. It will be available to download from the Website from 5 February 2018 to come into effect for postings from 26 March 2018.
If you declare postings to us by Zone, you must use Release 27 for postings due for handover to us from 26 March 2018. Release 27 is optional for all other types of customer declarations but we recommend its use as the most up to date postcode sortation file. You will need to advise your software supplier or IT department to effect its implementation.
