Street naming & numbering

We control the naming of streets and the naming and numbering of properties under Sections 17-19 of The Public Health Act 1925. 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. Addressing properties for locating purposes becomes increasingly important within a rural county like Carmarthenshire where a lot of roads do not have official street names.

The Street Naming and Numbering service is required if:

  • You have built a new property
  • You have converted a property like a barn into a dwelling, or a single property into flats.
  • You wish to rename your property
  • You wish to add a named to an existing numbered property
  • You have built a new development of more than one dwelling. This may include naming any roads within the development
  • You wish to amend layout of new developments that have already gone through the naming & numbering process.
  • Residents wish to rename and existing street
  • You require confirmation of an address

It is strongly advised that any Street Naming & Numbering applications made for new properties are submitted as early as possible in the development process. This will prevent any delay in obtaining services for the properties.

The allocation of a property name will be permitted but where and existing numbering scheme is in place, the name will be an addition to that number and not a replacement. The name must not already be in use by any other property, nor sound too similar to any other property in the area. A check will be undertaken on application. Names that sound racist, obscene or are open to misinterpretation will not be accepted.

Fees

  • None

Information Required

In the case of an owner wishing to change the name of an existing house, in an unnumbered street, we should be informed of the proposed name, via a completed application form.

We will consult with the Royal Mail on all applications received. This would hopefully avoid names being chosen that might be confused with others in the area that might lead to post going astray and the emergency services being delayed.

If the dwelling is a one-off between two others, in a numbered sequence, usually an “a” is given to the number of the dwelling to its right.  A requested name can also be given.

If it is a rural dwelling, and a number cannot be allocated then a name is chosen by the developer/owner.  It is requested that the developer/owner forwards any suggested house names to us, we will consult Royal Mail.  This ensures that the new property is officially registered.

In the case of developments in existing roads, where no new street name is required, we allocate postal numbers/names to new properties, in consultation with Royal Mail.

We will consult with the Royal Mail on all applications received. This would hopefully avoid names being chosen that might be confused with others in the area that might lead to post going astray and the emergency services being delayed.

This application is to be used for the naming and numbering of small development sites and where no new roads are to be constructed. If a new road or roads are to be constructed at your development site then road naming proposals will have to be agreed by the Council. Use form SNN3.

Fees

Information Required

To ensure that the process progresses as efficiently as possible, the developer is requested to provide the following information:

  1. Name and/or number for the new property;
  2. Location Plan;
  3. Correct fee (no details will be confirmed until the fee has been received).

When a new housing development is built, the responsibility for choosing a name rests with the developer. However, we need to be consulted by the developer, and in turn we consult with the community council, local councillors, Royal Mail and the emergency services.

If the developer has no proposed names for the development, we will request that the town/community council and local councillor(s) provide suggestions.  Once any suggestions are received, we will consult with Royal Mail.

Objections are sometimes raised to proposed names, mainly because the name could be confused with similar road names in the area. In such cases we would ask the developer/community council to think again and come up with alternative suggestions.

We will try to find attractive and meaningful names often with some local historical association.  Adoption of Welsh names for streets and new development will be promoted by giving due consideration to geographical, historical, cultural, demographic and linguistic factors.

We decide the numbering of new houses.  As you enter a development, it is usual that the odd numbers are on the left, with even numbers on the right.  If the development is small, the properties can be numbered in sequence, e.g. 1–7.

This form is to be used for the naming and numbering of large development sites where new roads are to be constructed. Official road naming will therefore be required. New road names must be approved by the Council. If a new road or roads are not to be constructed then use form SNN2.

For Solicitors and conveyancers who wish to receive official confirmation of postal addresses within Carmarthenshire.

Fees

  • £30

SNN7 - Confirmation of address (.pdf)

When a new development has been approved, addresses are created by the Council as ‘provisional’ entities. The details of the proposed development are shared with Royal Mail who subsequently ‘hold and record’ the addresses on their ‘Not Yet Built’ address database. To avoid any issues of post being sent to non existent properties the addresses are not activated until occupation or the properties are near completion and therefore are able to receive postal services.

As each property nears completion the developer will be required to notify the Street Naming and Numbering team and request that the address be activated for use. Upon notification confirmation will be issued to all internal services and external partners, including the emergency services. Royal Mail will be notified to ensure that the appropriate records are moved from their ‘Not Yet Built’ database into the Postcode Address File (PAF) making it available for general use and referencing across the United Kingdom within 24-48 hours, although this addition/correction can take several months to filter through to end users of Postcode Address File data. This will happen as external companies update their own databases with the latest Address Management Products over which Royal Mail have no jurisdiction.
