Unique Street Reference Number 14610160 is, according to Ordnance Survey OpenNames, Sedgefen Road in Suffolk.
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.
Roads operated by national highway authorities (eg, Highways England) will also have separate USRNs for the road as a whole and for each subsection within each local highway authority that it crosses.
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.
