OS Linked Identifiers API
The OS Linked Identifiers API allows you to access the valuable relationships between properties, streets and OS MasterMap identifiers.
This product is updated every six weeks
Benefit from the valuable relationship found in OS Premium Data. Link together datasets that are using different identifiers; for example, linking a property address (UPRN) to the street that it’s on (USRN).
The OS Linked Identifiers API gives direct access to identifiers for a large number of feature types such as address records, building outlines, road surface area, road names, road sections and street records as well as the relationships between them that we provide links for.
No need to download, store and manage large and complex datasets, we take care of that so you can focus on adding value.
Web developers can create clickable interactive web app maps for selection of road or building features. Search for a street name and highlight all the properties that are on it or visualise open data such as accident counts, pollution levels or average vehicle speed data using OS Open Roads
The OS Linked Identifier API only provides details of the related identifiers. Once you have the related identifiers, you can retrieve geometry and attribution via the OS Features API from either our OS Open Identifiers or Premium products.
