Webflow forms collect addresses as free text by default. With AutoPostcode, UK visitors search by postcode and select their exact address — filling your fields instantly.
Why Webflow builders add it
- Faster forms with higher completion rates
- PAF-verified addresses cut failed deliveries
- Cleaner lead and order data in your CMS or CRM
- Polished, professional UX on mobile
How to integrate
Add an embed or project-level custom code that calls the address autocomplete API and maps results to your form inputs. See the developer docs.
For developers
Building a custom front end? See React address autocomplete and the Postcode Lookup API hub.
