Geocoding

Postcodes.io integrations

Connect Postcodes.io to any other app, or use it from your AI client over MCP. Postcodes.io is an open UK postcode and geolocation service built on Ordnance Survey and ONS open data. Callers can look up a postcode to get its latitude/longitude, ward, district, county, parliamentary constituency and region; reverse-geocode coordinates to the nearest postcodes; validate a postcode; autocomplete partial postcodes; query outward codes; and bulk-look-up many postcodes or coordinate pairs in one request. It also returns random postcodes and nearest-neighbour postcodes. No credentials required.
