BigCommerce checkouts default to manual address entry. With AutoPostcode, UK shoppers search by postcode and select their exact address — filling billing and shipping fields in one tap.
Why BigCommerce stores add it
- Faster checkout and fewer abandoned carts
- PAF-verified addresses reduce failed deliveries
- Cleaner order data for shipping and analytics
- Smoother experience on mobile
How to integrate
Attach the address autocomplete API to your checkout's address fields and map results to BigCommerce's street, city and postcode inputs. See the developer docs.
