This release note provides information about the release of the AddressBase Core product on 17 September 2024.
| Product | Full Supply record count[*] | Change-Only Update record count |
|---|---|---|
*These counts are 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.
| Product | MGBS Full Count | National 5km tiled supply | Difference |
|---|---|---|---|
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:
