How this service works
UK postcode lookup (ONS Postcode Directory via postcodes.io): lat/lon, country, region, local authority, ward, parliamentary constituency, NHS ICB, police force, LSOA. Unknown postcode = not charged.
Output
Returns structured geographic and administrative data for the given UK postcode including: latitude and longitude, country, region, local authority district, ward, parliamentary constituency, NHS Integrated Care Board (ICB), police force area, and LSOA code. If the postcode is unknown or invalid, the request is not charged.
Example use cases
Enrich address records with admin boundaries
“I have a list of customer postcodes and I need to know which local authority and region each one falls in — can you look up EC2A 4PQ and give me those details?”
Route delivery by NHS ICB or police force area
“We're assigning field agents by health region — can you look up the postcode BS1 4DJ and tell me which NHS ICB and county it belongs to?”
Validate constituency for voter registration
“Can you check the postcode LS1 1BA and confirm which parliamentary constituency it sits in, along with the ward name?”
Technical details
Endpoint
GEThttps://gogeta2-u35175.vm.elestio.app/agents/v1/geo/uk-postcode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need accurate, ONS-sourced administrative boundary data for UK postcodes, including NHS ICB, police force, and LSOA — metadata that generic geocoding APIs do not provide. Prefer it over raw geocoding services when UK-specific administrative enrichment is the goal, and over manual lookup when automating at scale.
Side effects
- Unknown or invalid postcode returns a not-found response and is not charged
- Malformed postcode string (e.g. missing space, incorrect format) may return an error
- Postcode may be valid but not yet in the ONS directory if very recently assigned
