Street Naming and Numbering Explained

It is the responsibility of the local authority to issue official addresses for all residential and business premises within its area. These web pages aim to explain the rules and guidelines involved.  


The appropriate naming of streets, and the naming and numbering of buildings in streets, forms the basis for identifying property related information for the purposes of:

  • Enabling effective responses to emergencies by ambulance, police, and fire services.
  • Delivery of post by the Royal Mail and courier services.
  • Record keeping, for example, for legal transactions and billing. 

It is important that the use of street names and numbers are appropriate, logical, consistent, and are clearly displayed. You have a legal obligation to display your house number.


The renaming/renumbering of existing streets and buildings will normally only be considered if they pose a risk to the ability of the emergency services to locate a property. Also, any changes will resolve any problems with postal services and deliveries. We aim to make any changes in harmony with the parish/ward/town council and the residents. This means that occasionally the numbering schemes will to be reviewed or introduced. We are reminded by the Department of Transport the need to review and maintain logical numbering schemes.


Statutory Context
