AddressBrain

AddressBrain is a UK postcode lookup, address autocomplete and address validation API. Every lookup runs on Royal Mail’s Postcode Address File (PAF), officially licensed, so the addresses your customers pick are real, deliverable and returned as structured fields rather than a line of free text. AddressBrain is built and run by StoreFeeder Ltd, the team behind StoreFeeder.

What AddressBrain does

• Postcode lookup: enter a postcode and get every deliverable address at it, flats and house names included.
• Address autocomplete: suggest real addresses as a customer types, so they pick an address instead of typing one.
• Address validation: check an address against Royal Mail data before it reaches your warehouse, courier or CRM.
• Developer friendly: a REST API with an OpenAPI spec, a single bearer token, typical UK response times under 50ms and a free 30-day trial.

Where it fits with StoreFeeder

StoreFeeder manages orders, stock and despatch once an order arrives. AddressBrain works earlier, at the point the address is captured: on your own webstore checkout, a trade account form, or any system where customers type in a UK address. A correct, structured address at capture means fewer failed deliveries, fewer returned parcels and less time fixing addresses before labels are printed.

Built for developers

Two calls cover most checkouts: search as the customer types, then fetch the full PAF record for the address they choose.
