Street naming and numbering

The Council is responsible for the naming of all roads and streets, and for the naming and numbering of all properties (residential, commercial and industrial) within the City and County of Cardiff.


An address can only be created and given a postcode by Royal Mail once it has been officially named and numbered by the Council. Therefore if you are planning a new development, constructing a new property, converting an existing property, or wish to change the name of a property you must contact the Council's Street Naming & Numbering Officer who will assist you with the address creation or amendments required.


Failure to do so will mean that any address created will not be an official address and this will lead to problems. For example, the address will not be recognised by the Royal Mail, delivery companies or utility services; and difficulties may arise in relation to your registration for voting and the supply of credit cards. Moreover, Ambulance, Fire and Police services may experience difficulty in locating the address in the event of an emergency.


It should also be noted that the Council has the power to enforce changes to unofficial addresses in order to ensure compliance with standard conventions and that Council Policy for street naming and numbering is maintained. It is in your best interests to advise the Council of new naming and numbering requirements at the earliest opportunity.
