What Is a UPRN and Why Does Your Home Have One?
A UPRN is a unique reference number used to identify a property or addressable location. Learn what your home's UPRN is, why it matters and how it helps connect property information accurately.
UPRN stands for Unique Property Reference Number: a number, up to 12 digits long, used to identify an addressable location such as your home.
It gives organisations a consistent way to recognise the same property, even when its address is written differently in different systems.
For residents, that helps explain how information such as property details, energy records and repairs can be matched to the right home. A UPRN identifies the location; it does not itself contain those records or give anyone permission to access them.
How to find your home's UPRN
You can look up your home's UPRN using GeoPlace's FindMyAddress service, which covers England, Scotland and Wales.
Search for your address and check that the result matches your home, including the flat or unit number where relevant. You can then view the UPRN associated with that location.
The service is intended for personal, non-commercial use. You do not need to memorise the number, but it can be useful when checking that property information refers to the correct home.
Why does your home have a UPRN?
A UPRN gives your home a consistent reference that can be used throughout its lifecycle.
Government guidance describes UPRNs as the standard identifier for property and location information. They help organisations accurately identify locations, link information held in different datasets and reduce errors when information is exchanged between systems.
For a resident, the important point is simple: your address is how people usually recognise your home, while a UPRN gives data systems a precise way to recognise it too.
Is a UPRN the same as your address or postcode?
No. They are connected, but they do different jobs.
Your postal address is designed to help people and services identify where you live and deliver things to the right place. A postcode helps route mail, but it should not be used on its own to identify a particular home.
A UPRN is attached to a specific addressable location. In a block of flats, for example, individual flats can have their own UPRNs even though they share the same building and may share other location information.
This makes the UPRN particularly useful when information needs to be matched accurately to one property.
What information can be connected using a UPRN?
The UPRN itself is an identifier rather than a description of your home. It does not tell you whether your boiler works, when your roof was repaired or how energy efficient the property is.
Its value comes from helping information about the same location to be matched across systems and datasets.
Depending on the organisation and the data it is authorised to use, that could help connect different forms of property or location information without relying only on the way an address has been written.
For example, an Energy Performance Certificate can provide information about a home's expected energy performance, while other records may describe different aspects of the same property. A reliable property identifier helps create the foundations for connecting those pieces accurately.
Why are UPRNs useful in housing?
A housing provider might record the same flat slightly differently in its repairs system, inspection records and asset database. Matching those records by address alone can be difficult, particularly where several flats share a building address.
Using the same UPRN can help establish that the records concern the same location. That provides a clearer starting point for understanding the property's repairs, inspections and other information.
This is one reason connecting housing data matters. A consistent identifier supports accurate matching, but organisations still need to check the information itself and have appropriate permission to use or share it.
Does a UPRN change if you move house?
The UPRN belongs to the property or addressable location, not to the person living there.
If you move, you do not take the UPRN with you. Your new home will have its own identifier. The UPRN for your previous home continues to identify that location.
That distinction is useful because property information can remain associated with the correct place even as residents change over time.
Can more than one home have the same UPRN?
A UPRN is intended to uniquely identify an addressable location. Separate flats within the same building can therefore have separate UPRNs.
Government guidance notes that several UPRNs can share the same geographic grid reference, such as flats within one block, while still identifying the individual addressable locations separately.
How does a UPRN fit into the bigger picture of your home?
A UPRN is a good example of why property information becomes more useful when it is accurately connected.
On its own, a reference number tells you very little about what it is like to live in a home. The same is true of many individual property records. An EPC tells you something about expected energy performance. A repair record tells you about a particular issue or visit. Information from a resident can explain what is happening in the home now.
The challenge is making sure useful information refers to the right property and can be understood in context.
This is closely connected to the idea of property intelligence: moving beyond isolated pieces of property data towards a clearer, connected picture of a home.
Common questions about UPRNs
What does UPRN mean?
UPRN means Unique Property Reference Number. It identifies an addressable location, rather than the person who lives there.
Where can I find my UPRN?
For an address in England, Scotland or Wales, use FindMyAddress. Match the full address, including the flat number where relevant, before using the result.
Is a UPRN the same as a postcode?
No. A postcode can cover several addresses. A UPRN identifies a particular addressable location, so separate flats can have different UPRNs.
Better information starts with knowing the property
You do not need to memorise your UPRN. But knowing that your home has a persistent property identifier can help explain how different organisations and systems distinguish one property from another.
At House Krowd, we want residents to understand more of the information connected to their home, from energy information and property details to repairs and the experience of living there.
A UPRN is only one small part of that picture, but it provides something important: a consistent way to identify the home that the information belongs to.
