Alias addresses may reflect how the property has been known historically or includes a house name, locality or County information that isn't needed for postal purposes. However, you can choose to use whichever version of the address you prefer where alternatives are displayed.

Is the property new?

If the property you're looking for is a new build (or for example a house recently converted into flats), the postcode might not have been added to our database yet. If your address isn't listed please let us know. We'll try to get this fixed as quickly as possible.

If the property isn't new and you still can't find the address or postcode you're looking for, we recommend:

• Check your spelling and add as much detail as possible about the address to improve the results.
• If the address you're searching for uses a building name (eg, 'Media House', or 'Seaview Cottage') instead of a street address, we may be unfamiliar with the name. Try searching for the street address if you know it.
• Don't worry about abbreviations - we accept the most common abbreviations for addresses (eg 'Rd', 'St', 'Ave').

If you still can't see the address you're looking for please report it to us here.

Multiple versions of the same address

Sometimes this might happen when an address has a property name and not a number, or has both. You can use either to address mail, but generally it's better to use the property number, rather than name.

There are also occasions when you might see multiple results for a single address, for example a house converted in flats, where the mail is delivered to a single, shared front door. In these cases we show the main property number and street name, and then the property number with the individual flat number. For example, there may be three results; 3 High Street; 3A High Street; and 3B High Street, or 3 High Street; Ground Floor Flat, 3 High Street; and First Floor Flat, 3 High Street.

Technical problems?

If you can't see any results, we recommend trying a different browser - Google Chrome and Internet Explorer 10 or above generally work best with Postcode Finder. You'll be able to see the results on a map if you use Chrome, Safari, Firefox, IE 10 or above (it doesn't work with IE 8 or 9).

If you've noticed part or all of your address looks wrong in Postcode Finder please contact us to let us know.

Our address and postcode information is held in the Postcode Address File (PAF®). PAF is regulated in the UK by Ofcom.

Changes we can make to your address include:

• An incorrect or incomplete address
• A missing address
• A business name
• Properties converted into separate dwellings (e.g. converting a house into flats)

Please note: if you'd like to make a change to a property name or a street name, please contact your Local Authority.
