Please note: There will be no release of AddressBase Core on 31 January 2024 due to a company-wide shutdown over the festive period. The next release of AddressBase Core will be on 07 January 2025.

Please note that the Full Supply record count is based on a Managed Great Britain Set (MGBS). If you ordered your national coverage via the online ordering system using a polygon outline, your counts may differ.
There is a difference in record counts between taking a national Managed Great Britain Set (MGBS) and the national 5km tile supply. This is because the two supplies use different selection criteria. The difference in record counts is shown in the following table, allowing you to validate your data holdings once you have loaded the latest release of AddressBase Core.

A small difference in record counts is expected due to there being several features supplied in the MGBS which fall outside of the tiled area.
If you receive a Change-Only Update (COU) supply for your AddressBase Core product, you will receive Insert, Update and Delete records within the supplied file. The following table details the numbers of these records which can be expected in the COU supply of the product:
Inserts
8 535
Updates
87 373
Deletes
2 280
COU populated 5km tile count
3 960
One new issue has been identified in this release of AddressBase Core, causing an English record to be incorrectly matched to a Northern Irish POST_TOWN and POSTCODE. The UPRN = 10094417972 has been incorrectly assigned a ‘POST_TOWN’ of ‘BELFAST’ and an incorrect ‘POSTCODE’ of ‘BT12 4EA’. This address is affected in isolation, and the match will be fixed for the next AddressBase Core release.
The following information relates to the currency of the source data used in the creation of this release of AddressBase Core:

It is important that COUs are processed with Deletes first, then Inserts and Updates. This is to ensure that updates are applied in the correct order. Guidance on this can be found in the 'Working with COU data' page in the AddressBase Core Getting Started Guide.
