Street naming and numbering

We are responsible for naming all streets and for the numbering or naming of properties within the Caerphilly county borough area.

We have a statutory responsibility to ensure that any new or amended street and property names and/or numbers are allocated logically and in a consistent manner.

Royal Mail has no statutory power to name a street, name or number a property or rename or renumber a property; however, it does have the sole duty of issuing or amending postcodes once the address details have been confirmed by the council.

Regulating the addressing of properties within the county ensures that consistency and accuracy is maintained and helps with service delivery and most importantly ensures emergency services can locate the address.
