Street Naming and Numbering

This page contains details of the procedure of street naming and numbering including new developments and single properties, who is responsible for administering postcodes and how to request a property number or street name and information regarding obtaining a postcode from Royal Mail.


Street naming and numbering is a statutory function. 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 1925. This legislation requires the local authority to prepare street naming and numbering schemes and to maintain a good standard of street name plates.

New estates

It is important that developers apply to the Council at an early stage for a street numbering and naming scheme. The Council will consult with the relevent Electeced prior to an official scheme being issued. We will normally ask the developer for suggestions for street names based upon the history and/or locality of the area. Provided those suggested are not similar to any street name that already exists in the area, these may be put forward for approval to the Services Committee.

Following agreement with the developer to the proposed street naming and numbering, we will notify the relevant authorities and statutory undertakers of the approved scheme. Royal Mail will be asked to allocate postcodes. Royal Mail will not issue a postcode until informed by the local authority that an address has been allocated. An address is not complete without the correct postcode.

When the street name has been agreed a layout plan and a street numbering and naming schedule is prepared. This allocates a number and street name to the each of the developer’s plot numbers. Purchasers of new properties should be careful when passing on their new address details that they are using the postal number and street name, not the plot number and development name, as the two will not necessarily be the same.

Small developments

Single properties or small developments are generally built on infill plots, large gardens or on the site of previously demolished properties. These will be numbered within the existing sequence. Where this is not possible, letter suffixes (for example 1A, 1B and so on) will be used where necessary. Where a development takes the place on the site of a demolished property, the new building may inherit the existing number.

Building names

Whilst we have no objection to a house name being added to an existing postal address it cannot replace the street number, which must always be used.

It is a requirement that all properties must have a street number and not a house name alone, as a number readily identifies the location of a property in a road. The only exception to this will be on the rare occasions, where a street numbering sequence does not exist. When this does occur, we will accept the use of a building name to identify the property.

Street numbers and building names must always be prominently displayed where they can be easily read from the public highway.

Street name plates

When a road is built as part of a new development, it is the responsibility of the developer to arrange for the installation of the appropriate street name plate to the Councils specification. Building Control can faciliate the provison of these plates on a cost recharge basis.

Street name plate repairs or replacements can be reported by telephone on Leicester (0116) 257 2830, in person at our Customer Service Centres or you can .

Requesting a property number and street name

Any request for a new or revised property number or street name must be submiited on the appropriate fee and application form, this can be found within the related documents at the foot of this page. Your application should be submitted to the Building Control Section, Council Offices, Station Road, WIGSTON, Leicestershire, LE18 2DR. A site plan must be submitted with the request on paper no larger than A3. The plan must indicate the property or properties the request relates to.


The Council are not responsible for the issuing of new postcodes. All matters relating to postcodes are the responsibility of Royal Mail. However, Royal Mail will not issue a postcode for a new street or property until they have been officially notified of the scheme by the Council.

Postcodes for commercial premises are allocated in the same way as residential premises but some companies or businesses can apply to Royal Mail for its own unique code (known as a large user code). If you receive at least 500 items of mail a day you may be eligible for a unique large user postcode. Applications for a large user code are the responsibility of the end user and should be made direct to Royal Mail.

All enquiries about postcodes should be dealt directly with Royal Mail.
