1. These counts are based on a Managed Great Britain Set (MGBS). If you have ordered your national coverage via the online ordering system using a polygon outline, then your counts may differ.

2. Change-Only Updates are not available for the OS Open UPRN product.

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.

Data Issues

AddressBase Plus Issues

Affected output formats: CSV and GML

• There are 6 189 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 254 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 111

Valuation Office Agency Matching

The match rates for Council Tax and Non-Domestic Rates for Epoch 111 are detailed as follows based on Valuation Office Agency (VOA) records up to 20th May 2024. The match rate is applicable to the AddressBase Premium product.

Data Source	Records Received	% Matched
Council Tax	27 084 483	99.94
Non-Domestic Rates	2 123 193	96.48

Tertiary Classifications

Work is being undertaken to improve the classifications of records within the AddressBase products. This work has resulted in 40 932 more tertiary classifications present in Epoch 111 compared to Epoch 110. Indeed, 88.74% of these tertiary classification improvements are against residential codes.
