Street naming and numbering

The address of a property is important as many organisations, postal, emergency services and the general public need an efficient means of locating and referencing properties.

If a property is not ‘registered’ through the street naming and numbering process it will not appear on the main address database and the owner/occupier will encounter difficulties in obtaining mail, goods and services from a variety of sources (e.g. applying for a credit card, or purchasing goods by mail order).

The main address database is used by the Council, Royal Mail, all statutory undertakers, emergency services, credit agencies, satellite navigation system suppliers and many private companies.

How to get a new address

Blackburn with Darwen Borough Council are responsible for allocating house numbers and road names to new developments and property conversions. Individuals and developers must not allocate their own house numbers, building or street names.

We also maintain the definitive record of all street names and property addresses (called the Local land and property Gazetteer).

Apply for a street name or postal number

You should apply if you are building new houses, commercial or industrial premises or undertaking conversions of residential, commercial or industrial premises which will result in the creation of new properties or premises.

You should apply once you have received planning permission in the early stages of any new build or conversion. Utility companies will not install services without an official postal address and postcode.

Please forward your details, along with planning application number (if relevant) to: or call 01254 585698.


If your request relates to a new address on an existing street under normal circumstances we will allocate a postal address the following working day from receipt of a valid application.

If your request involves the naming of new streets due to the potential consultation process with local ward councillors, under normal circumstances we will allocate a postal address within 28 working days from receipt of a valid application.
