ONS UPRN Directory: Great Britain Address to Geography Linkage (October 2023)

The ONS UPRN Directory (ONSUD) relates the Unique Property Reference Number (UPRN) for each address in Great Britain to a range of current statutory administrative, electoral, health, and other statistical geographies. It is produced by ONS Geography and issued every 6 weeks to complement the Ordnance Survey AddressBase® product. This version is for October 2023 and was amended on 06/12/2023 to correct a corrupted file.

Use Cases

• Enrich address data with administrative geography codes based on the linked statutory geographies.
• Analyze electoral or health service coverage based on the address-to-geography relationships.
• Perform spatial joins and aggregations using the UPRN as a stable property identifier.
• Validate or standardize address data against the authoritative AddressBase® reference system.

Strengths

• Links every address in Great Britain to multiple current statutory geographies.
• Issued on a regular 6-week update cycle, suggesting ongoing maintenance.
• Produced by ONS Geography, an authoritative source for UK geographic data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Contains intellectual property from multiple organizations (Royal Mail, Gridlink, Ordnance Survey, ONS), which may impose usage restrictions.
