Future and past publication dates

AddressBase, AddressBase Plus, AddressBase Premium and AddressBase Islands are updated every six weeks. This six week period of time is known as an epoch.

Our AddressBase products are currently available as a Full Supply or Change-Only Update (COU) for each epoch.

Future dates are provided as an indication only and are subject to change. Data cut dates are estimates; these are given to provide an indication of the last point at which changes will reach the epoch.

As we approach the publication date and prepare to release a new epoch, any new requests placed for data will be paused to ensure data integrity. These requests will be processed as soon as this pause is lifted.

AddressBase Core is a weekly supply and information is covered in a separate AddressBase Core release note.
