What is a UPRN?

A UPRN, or Unique Property Reference Number, is the official identifier for an addressable place in Great Britain. Every house, every flat and every block of flats has one. Councils create them, and GeoPlace and Ordnance Survey keep them in the national address register.

An address can be written many ways ("Flat 2, 10 High St" or "10B High Street"), but the UPRN is always the same. That is why councils, utilities, broadband providers, insurers and conveyancers use it to be sure they mean the same property.

Common questions

What is a UPRN?

A UPRN (Unique Property Reference Number) is a number of up to 12 digits that identifies one addressable place in Great Britain, such as a house, a flat, a shop or a block of flats. Councils create them and they are brought together in the national address register maintained by GeoPlace and Ordnance Survey.

How do I find my UPRN?

Type your address or postcode into the box on this page. The matching homes appear with their UPRN, which you can copy straight away, and a link to each home's free Planna report.

Does a UPRN ever change?

No. A UPRN stays with a property for its whole life, even if the street is renamed or the house number changes. A new UPRN is only created when something new is addressed, for example when a house is converted into flats or a new building goes up.

Do flats have their own UPRN?

Yes. Each flat has its own UPRN, and the building it sits in has a separate UPRN of its own.

Why would I need my UPRN?

Councils, utilities, broadband providers, insurers and conveyancers use the UPRN to be sure they mean exactly the same property, because two addresses can be written in many ways but a UPRN cannot. Some forms ask for it directly.

Is the UPRN lookup free?

Yes. Finding a UPRN and seeing the home's report are free, and you do not need an account.
