What a UPRN is
A Unique Property Reference Number (UPRN) is the official numeric identifier assigned by Ordnance Survey to every addressable location in Great Britain. There are around 40 million UPRNs in total, covering every dwelling, commercial property, and other addressable place. Each UPRN is unique, permanent, and stays with the location even if the building is rebuilt or the address changes.
UPRNs are used by:
- Local authorities for council tax, planning, refuse collection, and electoral registration
- Emergency services for incident location
- Utility companies for service connection
- HM Land Registry as a property identifier
- The EPC Register
- Postal and delivery services
- Property Passport UK
Why UPRNs matter
A UPRN is the most precise way to identify a UK property. Address text strings can be ambiguous: "Flat 1, 22 Acacia Avenue" might refer to two different flats if the building has been re-numbered, and address formats vary between databases. A UPRN does not. It is one number, it is unique, and it points to exactly one location.
When data from different sources needs to be linked (EPC data, Land Registry sold prices, Environment Agency flood data), the UPRN is the only reliable join key. This is why Property Passport UK uses UPRNs as the underlying identifier for every record.
How to find a UPRN
Property Passport UK
The fastest way for any UK address. Search the address or postcode on Property Passport UK at [/search](/search). The platform shows the UPRN on the property page for every one of the 19.35 million properties in England and Wales.
FindMyAddress (Ordnance Survey)
Ordnance Survey runs a free public service at findmyaddress.co.uk that returns the UPRN for any address in Great Britain. Search by postcode or address.
Local Authority website
Most local authority websites have an address look-up that includes UPRN, although it is sometimes hidden in council tax or planning records.
EPC Register
The official EPC Register shows the UPRN alongside the EPC certificate for any property that has had an EPC assessment. Search at epcregister.com.
What you can do with a UPRN
Once you know the UPRN, you can:
1. Look up the property on Property Passport UK directly via UPRN at [/search](/search) (or use [/uprn](/uprn))
2. Cross-reference the UPRN against multiple data sources to confirm you are looking at the same property in each
3. Submit precise location to insurers, utility companies, and conveyancers
4. Search planning portal records using UPRN as a filter
5. Verify your property is correctly registered for council tax, electoral roll, and other purposes
UPRN vs USRN
A USRN (Unique Street Reference Number) identifies a street, not a property. USRNs and UPRNs work together: a property has one UPRN and is on one street with one USRN. USRNs are mainly used by highways authorities and utility companies for road and street references.
UPRN vs UDPRN
UDPRN (Unique Delivery Point Reference Number) is the Royal Mail equivalent for postal delivery points. Most properties have both a UPRN and a UDPRN, and they usually match, but in cases of multi-occupancy or unusual delivery arrangements they can diverge.
For property data purposes, UPRN is the right identifier. UDPRN is mainly used by mail and delivery services.
Why UPRN matters when buying a property
When buying:
1. Confirm the UPRN matches the address you think you are buying. Address strings can be confusing in flats and converted buildings.
2. Use the UPRN to look up the EPC independently of what the agent quotes
3. Use the UPRN to look up Land Registry sold prices to verify recent transaction history
4. Include the UPRN in your conveyancer's instructions so there is no ambiguity about which property is being bought
Property Passport UK uses UPRNs throughout to ensure data accuracy. When you search at [/search](/search), the platform shows the UPRN for every result so you can verify you are looking at the right property before going further.
