Magento's default checkout asks customers to type every address line by hand. With AutoPostcode, UK shoppers search by postcode and select their exact address, filling billing and shipping fields instantly.
Why Magento merchants add it
- Faster checkout and reduced cart abandonment
- PAF-verified addresses cut failed deliveries and reships
- Cleaner order data for fulfilment, ERP and CRM
- Better mobile conversion on long checkout forms
How to integrate
Call the address autocomplete API from your checkout theme or a custom module, then map results to Magento's street, city and postcode fields. See the developer docs for request and response formats.
