Address Lookup resolves customer-supplied address fragments into verified, structured service addresses. It is designed for phone, SMS, email, and form intake where a customer may provide anything from a postcode and house number to a messy full address.
UK addresses resolve at individual flat and property level — every premise for a postcode, with sub-building, UPRN, and UDPRN. Global addresses resolve from free text with house-number precision. Ambiguous results return ranked candidates and a clarification question rather than silently guessing.
What you can do
- lookup_postcode — validate a postal code and return every individual premise, ready for the agent to ask which one the customer means
- resolve_address — resolve messy full address text globally, or match postcode plus spoken property detail to one exact address
- autocomplete_address / autocomplete_postcode — typed address suggestions, or complete a partial postcode
- reverse_geocode — turn a latitude/longitude into the nearest UK postcode and admin areas
- validate_postcode, search_postcodes, nearest_postcodes, bulk_lookup_postcodes, lookup_outcode — UK postcode utilities for forms, batches, and area routing
- search_places — find UK towns, suburbs, and landmarks by name
- terminated_postcode — check whether a postcode was retired by Royal Mail
Who it's for
Voice agents, field-service teams, delivery teams, CRM intake flows, and operations software that must capture the exact service address before routing someone or saving a customer record.
How to use it
- Use resolve_address when the customer gives a complete or messy address in SMS, email, or chat
- Use autocomplete_address while the customer types an address into a form or chat UI — or autocomplete_postcode to complete just the postcode
- Use lookup_postcode when the customer only gives a postcode — returns every premise so you can ask "which number or flat?"
- Use reverse_geocode to turn a GPS coordinate (e.g. a driver's location) into the nearest postcode and area
- If the result is ambiguous, read back the candidate labels and ask the customer to pick one — never assume
- For a named business or shop, switch to the places-search tool instead
Getting started
Works with no configuration. Add a UK address credential for flat-level UK data including UPRN and UDPRN; the postcode utilities need no setup.
