Squarespace forms default to manual address entry. With AutoPostcode, UK visitors search by postcode and select their exact address — filling your fields in one tap.
Why Squarespace sites add it
- Faster forms and checkout, fewer drop-offs
- PAF-verified addresses reduce failed deliveries
- Cleaner enquiry and order data
- Better experience on mobile
How to integrate
Inject a small script that calls the address autocomplete API and maps results to your Squarespace fields. See the developer docs for request formats.
