Product Supply Comparison
There is a difference in product counts between taking a national Managed Great Britain Set (MGBS) and a national Area of Interest (AOI). This is because the two supplies use different selection criteria. The differences are shown in the following table, allowing for you to validate your data holdings once you have loaded the latest release of AddressBase data.
The national AOI refers to the pre-selection GB polygon from our download store. Therefore, if you have drawn your own AOI, the count will vary.
If you are unsure of your supply type, please check this with your OS Relationship Manager.

Guidance on this can be found in the Working with COU data page in the Getting Started Guides for AddressBase, AddressBase Plus and AddressBase Plus Islands.

Data Issues
AddressBase Plus Issues
Affected output formats: CSV and GML
There are 5 420 Unique Property Reference Numbers (UPRNs) which reference a Parent UPRN which cannot be found in the product. This is because the Parent UPRN is either provisional or historic and is not matched to the Royal Mail Postcode Address File (PAF) or Valuation Office Agency (VOA) record, meaning that it is not included in the AddressBase Plus product as per the existing background logic rules.
There are 240 records with a sao_start_no or sao_text that have no Parent UPRN in the product. This is because the Parent UPRN is a historical record which is included as part of the logic for record inclusion in the AddressBase Plus product.
Improvements in Epoch 110
Valuation Office Agency Matching

Council Tax | 27 058 858 | 99.92 |
Non-Domestic Rates | 2 123 768 | 96.44 |
