Street naming and numbering

We are responsible for the naming of all roads as well as the naming and numbering of all properties (residential and commercial) within Denbighshire.

An address can only be created and given a postcode by Royal Mail once it has been officially named and numbered by us.

You can view our street naming and numbering policy for further details. 

New properties and address changes

You will need to complete an application form for the following:

  • Naming streets on a new development
  • Constructing a new property
  • Converting an existing property
  • Changing the name of a property

Complete an application form

Once we have created/amended an address, we will provide confirmation of the full address including the postcode of the property.

Where is the information held?

The Local Land and Property Gazetteer (LLPG) is a central database that provides the definitive identification of all land and property within the county. 

Many other departments such as Planning, Council Tax, Non Domestic Rates and Electoral Registration use the data. The database is also linked to the National Land and Property Gazetteer (NLPG), a national address database for England and Wales that drives applications and services at a regional and national level.

The database enables address changes to be made once and shared across all other departments ensuring consistent use of the information.
