OS Names API support

OS Names API lets you search the OS Open Names gazetter dataset over the Internet to support your internal and external applications.

How do the OS Names APIs work?

An API, or application programming interface, defines how two applications communicate. They could be enterprise software or simply websites with databases in the background.

Our APIs let your website or internal application request information about place names, road numbers and postcodes from our OS Open Names database and display them on screen to your user. Typical uses include where is and where's my nearest searches.

You submit your query via an HTTPS GET request; results will be returned as either XML or JSON. For more detailed information, please see the user guide.

Is the API INSPIRE-compliant?

No, the OS Names API isn't INSPIRE compliant. The OS Open Names data product specification extends the Infrastructure for the Spatial Information in the European Community (INSPIRE) Geographical Names Theme to ensure it complies with European open data initiatives.
