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 AddressBase epoch publication dates

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.
