Public sector address validation confirms that a citizen's address is a real, correctly formatted UK delivery point against Royal Mail PAF, and links it to its Unique Property Reference Number (UPRN). For UK councils and government departments it keeps records accurate and joined up — validating against the ~31 million UK addresses PAF holds across ~1.8 million postcodes.
Why does the public sector need accurate address data?
Because unreachable citizens mean missed correspondence, duplicated records and service failures across benefits, council tax and social care. Validating against PAF and linking to a UPRN at capture keeps every record accurate and matchable across departments.
- Accurate, standardised citizen addresses at capture
- UPRN linkage for cross-service record matching
- Fewer duplicated and unreachable records
- Clean data across case management and portals
How does UPRN linkage join up citizen data?
By giving every property a single, persistent identifier that survives inconsistent typing. Instead of matching messy address strings, departments match on UPRNs — pairing well with UK address verification for ongoing accuracy.

Frequently asked questions
What is public sector address validation?
Public sector address validation confirms that a citizen's address is a real, correctly formatted UK delivery point against Royal Mail PAF, and can link it to its Unique Property Reference Number (UPRN). It keeps government and council records accurate, consistent and joined up across services.
Why do councils and government need accurate address data?
Because inaccurate addresses cause missed correspondence, duplicated citizen records and service failures across benefits, council tax and social care. Validating against PAF and UPRN at capture ensures every record holds a genuine, standardised UK address that different departments can match.
What is a UPRN and why does it matter for public sector data?
A UPRN is a Unique Property Reference Number — a persistent identifier assigned to every addressable location in Great Britain. Linking citizen records to UPRNs lets councils and government departments join data reliably across systems without depending on inconsistently typed address strings.
What address data should the public sector validate against?
UK public sector services should validate against Royal Mail's Postcode Address File (PAF) — roughly 31 million delivery-point addresses across around 1.8 million postcodes — and link to UPRNs for authoritative, cross-service address matching.
Can address validation integrate with government service forms?
Yes. AutoPostcode is a REST API returning JSON, so it drops into online forms, case management systems and citizen portals. Verified, standardised addresses flow straight into the record at the point of capture.
Does address validation help reduce duplicate citizen records?
Yes. Standardising every address to a consistent PAF format, and anchoring it to a UPRN, makes duplicate detection and record matching far more reliable — supporting single-view-of-citizen and data-quality initiatives.
