With OS Names API, you’ll have access to a straightforward, rapid lookup service: drilling down into the details we hold in our OS Open Names dataset.
The API uses the OS Open Names dataset, a gazetteer or directory hosting detailed information about 2.5 million identifiable places in Great Britain including postcodes, roads and settlements.
A free, searchable, reliable database to help you find and verify populated places, road names, road numbers and postcodes. OS Names API is a reliable way of supporting the discovery or identification and visualisation of a named place; geocoding; routing and navigation, and linking diverse information such as statistics or descriptions. OS Names can locate a feature using just its name, or it can find the closest location to a given point.
