Street naming and numbering

We have a statutory responsibility for the naming and numbering of streets within the West Lindsey district. The relevant powers for local authorities are contained in Sections 64 and 65 of the Towns Improvement Clauses Act 1847, and Sections 17, 18 and 19 of the Public Health Act of 1925.

The legislation requires we prepare street naming and numbering schemes and to maintain a good standard of street nameplates. Both are essential for the efficient functioning of postal and emergency services as well as for the convenience and safety of the general public. The address data is held in our Local Land and Property Gazetteer (LLPG) which is continually maintained, and daily updates are sent to the National Land and Property Gazetteer (NLPG).

Before you start please read the information below. Additional information is also available to download: Street naming and numbering procedure

You can apply online for all street naming and numbering applications. The forms are also available to download and are listed at the bottom of the page.

Procedure for new estates

The developer will consult directly with the appropriate parish council to ascertain a suitable name. They will then approaches us to register the name. Following agreement with the developer we ask Royal Mail to allocate postcodes. Royal Mail will not issue a postcode until informed by us that an address has been allocated. 
Purchasers of new properties should be aware that the postal number and the plot number are not necessarily the same and should also check the street name isn’t the developer’s site name.

Procedure for individual properties

These will be numbered within the existing sequence if possible and letter suffixes (e.g. 16A) will be used if necessary. Where building takes place on the site of a demolished property, the new building may inherit the existing number.

Street nameplates

When a road is built as part of a new development it is the responsibility of the developer to arrange for the installation of a street name plate to the appropriate specification. Once roads are adopted, the maintenance and replacement of name plates becomes the duty of the West Lindsey District Council. We are also responsible for the repair and maintenance of existing street name plates within the district.


We are not responsible for issuing new postcodes. This is the responsibility of Royal Mail, however they will not issue a postcode for a new street or property until requested to do so by us.

Postcodes for commercial premises are allocated in the same way as residential premises, but a large company or business can apply to Royal Mail for its own code - known as a large user code. Application for a large user code is the responsibility of the user, as they will know what volume of mail they generate.
