Unique Street Reference Number 45405335 is, according to Ordnance Survey OpenNames, Solent Place in Evesham, Worcestershire.
Note: a USRN is an operational identifier and is unique to a highway authority. Where a road crosses a highway authority boundary, therefore, it will have different USRNs in different authorities, even if it has the same name and number. A road also has a different USRN for different sections that are classified or operated differently. The A1, for example, has several hundred different USRNs, covering different stretches in different counties and different sections that are trunk roads, primary routes, motorways and non-truck roads. So this USRN is not necessarily the whole of this road.
All the UPRNs which are associated with this road are shown. This does not necessarily mean that they have a postal address on this road. The USRN associated with a UPRN is, typically, the nearest significant public highway that the property is accessed from. Postal addresses may use a different street name.
It's important to bear in mind that UPRNs can overlap or stack. For example, a building containing multiple addressable units on different floors, such as a block of flats or a shop with a flat above it, will have a UPRN for each distinct unit. And an open air space, such as a park or square, can also have distinct addressable objects within it such as a kiosk or a structure. Given the limitations of a 2D map, you can't necessarily tell which of several overlapping or adjacent UPRNs is assigned to a specific item on the map.
