How this service works
UK postcode lookup: coordinates, country, region, local authority, ward, parish, parliamentary constituency, LSOA/MSOA and official ONS codes. Pass ?postcode=SW1A1AA, or ?lat=51.5&lon=-0.12 to find the nearest postcodes. Official ONS data via postcodes.io.
Output
A JSON object with a 'found' boolean, licence attribution, and a 'results' array. Each result contains the postcode, outcode, latitude, longitude, eastings, northings, country, region, county, district, ward, parish, constituency, LSOA, MSOA, and an ONS codes object with official area identifiers.
Example use cases
Enrich delivery address with admin data
“I have a customer address with postcode EC2A 4NE — can you look it up and tell me the local authority district, region, and LSOA code so I can tag it in our records?”
Reverse geocode field survey location
“I'm at latitude 53.8008 and longitude -1.5491 in the UK — what's the nearest postcode and which ward, constituency, and district does it fall in?”
Validate and geolocate user-submitted postcode
“A user submitted the postcode M1 1AE on a form — look it up and return the country, region, coordinates, and parliamentary constituency for me.”
Technical details
Endpoint
GEThttps://aayatai.com/uk/postcode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official ONS administrative geography data (LSOA, MSOA, constituency, ward, district) for UK postcodes, or when you need to find the nearest postcode to UK coordinates. It is authoritative, cheap per call, and covers the full ONS dataset. Prefer over general geocoding APIs when UK-specific administrative codes are required.
Side effects
- Invalid or malformed postcode returns found:false with an empty results array
- Lat/lon outside UK bounds (lat 49–61, lon -9–3) may return no results or an error
- Missing both postcode and lat/lon query parameters results in an error response
- Terminated or non-existent postcodes may return found:false
