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 estimated; these are given to provide an indication of the last point at which changes will reach the epoch.
Please note: 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.
