Address verification API for e-commerce
Turn a clunky address form into a single, fast lookup. Locatebase helps online stores reduce cart abandonment, prevent failed deliveries, and capture clean, structured address data at checkout.
Why checkout addresses matter
Manual address entry is one of the biggest sources of checkout friction and delivery failure. Typos, missing unit numbers, and wrong postcodes lead to returns, redelivery costs, and unhappy customers.
With postcode-driven autocomplete, shoppers select their address in a couple of taps. You capture a verified, structured record every time, and your fulfilment team gets addresses that actually deliver.
What you get
- Address autocomplete — Suggest full addresses as the customer types a postcode.
- Validation at submit — Confirm the address exists before the order is placed.
- Structured fields — Receive clean line 1, line 2, town, and postcode fields.
- Fast responses — 75ms average keeps checkout snappy on any device.
Built to drop into any stack
A single REST endpoint returns clean JSON, so it integrates with custom checkouts, headless storefronts, and popular platforms alike. Start in our docs and ship in an afternoon.
