Address autocomplete best practices for checkout
Design tips for fast, accessible address autocomplete that lifts conversion and captures clean data.

Make it fast and forgiving
Autocomplete should feel instant. Debounce input, show results quickly, and tolerate partial or messy postcodes. Every extra moment of latency erodes the experience you are trying to improve.
Keep a manual fallback
Always let users enter an address manually if they cannot find theirs. New-build and edge-case addresses do exist, and a dead end at checkout costs you the sale.
Design for accessibility
- Keyboard support — Users should navigate suggestions with arrow keys.
- Screen readers — Announce results and selection clearly.
- Mobile first — Large tap targets and minimal typing.
