It may be the case that you need to search more accurately by entering more information. Please see the above FAQ "How do I search for an address?".
Alternatively, it could mean that the property you are searching for is still under review by your local authority, for example if it is new and still progressing through the planning processes.
If you don’t believe this is the case, and you still cannot find the address you are looking for, then please report this to Ordnance Survey via the OS Data Hub. Please note you will need to sign up and create a user account in order to do so. Once reported, you will be able to view your address issue and be notified with status updates as it progresses.
The data behind FindMyAddress contains alternative (alias) addresses which are captured by local authorities where known.
For example, a property may officially be known to the local authority by its building number only such as “15 Church Drive”. However, through the use of a nameplate or historical local precedent, it may be unofficially known as “Sunshine Cottage, Church Drive”.
If the local authority is aware of this then “Sunshine Cottage” will exist as an alternative (alias) address, meaning both representations will be searchable in FindMyAddress and AddressBase®.
Any modifications to, or designation of an officially known address must go through the respective local authority’s Street Name and Numbering process.
When using FindMyAddress, if a property has an alternative address, it is always better to use the representation that contains the building number as this helps with locating the property along the street.
FindMyAddress uses both the geographic Town (officially assigned by local authorities) and Royal Mail’s Post Town to construct an address. Where these are the same then only one occurrence is displayed.
If the above does not answer your question, then please report this to Ordnance Survey via the OS Data Hub. Please note you will need to sign up and create a user account in order to do so. If you are reporting an issue against an address found in FindMyAddress then please make a note of its UPRN as this can be used to search for the property in question.
Once reported, you will be able to view your address issue and be notified with status updates as it progresses.
Royal Mail is the authoritative organisation which owns and assigns all postcodes in the UK for the purposes of delivering mail. To check your officially assigned postcode or if you have a query, then please visit the Royal Mail website.
FindMyAddress is underpinned by Ordnance Surveys AddressBase® Premium product which comprises local authority address data along with Royal Mail postcode data (PAF®). It also assigns postcodes to physical features and objects that don’t receive mail such as open spaces and telephone boxes which is why you will see these with a postcode.
For further information, please see Ordnance Surveys AddressBase® range of products.
GeoPlace assigns a range of UPRNs to each local authority and to Ordnance Survey. The UPRNs are then allocated to individual properties, areas of land and objects. In addition, Ordnance Survey also allocates UPRNs to unique objects in the landscape that otherwise wouldn’t have a ‘normal’ address, such as a pond, electricity substation or a communications mast.
We use the phrase “official address” to mean that the postal delivery addresses displayed in FindMyAddress originate from the authoritative creators of this data. These data creators are local authorities and Royal Mail respectively.
Local authorities have a legal responsibility to name streets and number buildings within their respective boundaries to which Royal Mail, for postal delivery purposes, then create and assign their “post town” and “postcode” to.
When this data is combined (as seen in FindMyAddress), this is what we term the “official address” as these are drawn from the official data creator sources.
There are currently 562 different property classifications that exist in FindMyAddress. These include:
Parent Shells (for example a named block containing individual flats)
Objects of Interest / Unclassified / Other properties
A full list can be downloaded from the Ordnance Survey website.
To help improve your search experience, FindMyAddress excludes “Street Records” which are used to represent a street rather than a property.
The property lifecycle
As well as “live” properties (currently in use), FindMyAddress also includes “provisional” properties, for example those created for proposed or current planning developments.
“Historical” records have been excluded in order to improve your search experience. These are properties which have been demolished or are no longer in use. Historical records can be found in the AddressBase® range of products.
If you are experiencing any problems or have any questions about FindMyAddress then please let us know by using the red “Report Feedback” tab on the right-hand side of the web page.
Please provide as much detail as possible as this will help us investigate the issue more thoroughly and aid communication with the respective local authority if needed. We will aim to get back to you within 28 days.
