Wix Postcode Lookup

Add UK postcode address lookup to your Wix store checkout. Customers type their postcode, pick their address — and move straight to payment.

What It Does

This integration adds a postcode lookup field to your Wix store checkout. When a customer enters their UK postcode, a list of verified Royal Mail PAF addresses appears. They select their address, the form auto-fills, and they're ready to pay — without typing a single line of their address manually.

  • Postcode lookup integrated directly into Wix checkout
  • Returns verified Royal Mail PAF addresses for any UK postcode
  • Checkout address fields fill automatically on selection
  • Works on desktop and mobile
  • Reduces cart abandonment from address entry friction
  • Fewer failed deliveries from customer address errors
  • UK addresses only — built for British postcodes
