The checkout address form is one of the highest-friction moments in ecommerce. Every extra field is a chance for the customer to mistype, hesitate or leave. Address autocomplete collapses that into a single, confident action.
What good autocomplete delivers
- Fewer keystrokes — customers pick instead of type
- Fewer errors — addresses come from Royal Mail PAF data
- Faster checkout — less friction, lower abandonment
- Cleaner data — correctly formatted addresses downstream
How it works
As the shopper types, your form queries an address autocomplete API and shows matching addresses. One tap fills street, town and postcode — verified and ready.

Frequently asked questions
Does address autocomplete improve conversion?
Yes. Autocomplete reduces the number of fields a customer types, cuts errors and abandonment, and typically speeds checkout completion — all of which lift conversion.
How does checkout address autocomplete work?
As the customer types a postcode or street, a lookup API suggests matching PAF-verified addresses; selecting one fills the full address instantly.
Will it reduce failed deliveries?
Yes. Because addresses come from Royal Mail PAF data, they're real and correctly formatted, reducing mis-deliveries and address-related support tickets.
