5.2.6 Type 4 Street – Other named Street with an unofficial Street Name
This is any other Street Name or number that references a Street or part of a Street and is not normally designated by the SNN Authority or the LHA. It includes long distance footpaths, cycle paths and trails. Examples are:
- “Lovers Lane”.

The first use of a type 4 Street is the entry of a locally known name of an officially named (or officially described) Street, for example, “Lovers Lane”, “Main Street”, “Great North Road”, or a by-pass name. The second use is the aggregation of several roads together to make an official route.

The Authority Address Custodian and the Authority Street Custodian must have an information exchange process in place.

A USRN is a persistent unique integer value taken in sequence from this range. For more information about USRNs, see Appendix B.
5.2.17

Classified Roads are Streets which are declared ‘classified’ by the DfT or the LHA under various statutory provisions.
5.2.19
A Street is declared a Classified Road to differentiate it from other Streets for transport and planning legislation purposes.
5.2.20 Procedure when it is proposed to change the USRN of an existing length of Street
5.2.18.1 If a change to the USRN for a length of Street is proposed by the Authority Address Custodian, they must consult the relevant Authority Street Custodian before making any changes.
5.2.18.2 This is because the Authority Street Custodian has a statutory duty to consult with other organisations which have an interest in lengths of a Street.
5.2.18.3 If any of the following organisations have an interest recorded in the ASD Records for the USRN of that Street, the Authority Street Custodian must consult with them:
- Highways England.
- Network Rail.
- Neighbouring LHAs who have an interest Record in that USRN.
- Various regional bodies.
- Welsh Assembly Government
5.2.18.4 Changes which must be consulted upon include:
- Splitting a USRN into two or more USRNs.
- Combining two or more USRNs into a single USRN.
- Moving a section of Street from one USRN to another USRN.
5.2.18.5 If an Authority Address Custodian proposes any of these changes they must inform the Authority Street Custodian of the proposed change and ask if a consultation is needed before the change is made.
5.2.18.6 If any organisation has recorded an ASD Record against any USRN affected, then a consultation is necessary, and the Authority Street Custodian must inform the Authority Address Custodian that the consultation is needed.
5.2.18.7 When the consultation is complete, the Authority Street Custodian must inform the Authority Address Custodian, so any changes are made in both the LLPG and LSG at the same time.
