Ordnance Survey Names API

Search Great Britain's gazetteer of place names, roads, postcodes, and geographic features via the OS Data Hub.

Data Model

  • GazetteerEntry — Each result has NAME1 (primary name), TYPE (categorised/populatedPlace/transportNetwork), LOCAL_TYPE (City/Town/Village/Postcode/Named_Road etc.), GEOMETRY_X/GEOMETRY_Y (British National Grid easting/northing), POPULATED_PLACE, COUNTY_UNITARY, REGION, COUNTRY.
  • Header — Response metadata: totalresults, maxresults, offset, query.

Gotchas

  • Coordinates are British National Grid (EPSG:27700), not lat/lon. GEOMETRY_X is easting, GEOMETRY_Y is northing.
  • fq filter uses LOCAL_TYPE: prefix: e.g. LOCAL_TYPE:City LOCAL_TYPE:Town (space-separated for multiple).
  • maxresults cap is 100 per request. Use offset for pagination.
  • nearest requires BNG point: format is easting,northing (e.g. 437292,115541 for central London).
  • OS OpenData path: The Names API sits on OS OpenData; throughput still follows OS Data Hub account rules.
