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.

Let's check a few things:

The address details entered on Postcode Finder

Please check the following and retry:

• The spelling and enter as much information as possible.
• If the property has a building name, try searching using the street address instead.
• Common abbreviations such as "Rd", "St" and "Ave" are recognised automatically.

Property names and numbers

Some properties can be identified by either a property name or a property number. Where possible, search Postcode Finder using the property number as this usually provides the most accurate result.

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 the name.

There are also occasions when you might see multiple results for a single address, for example a house converted into 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.
