Switch off address autofill per field — postal code, city or region
Keep street autocomplete working while blocking only the fields that get it wrong
Correct wrong city or region automatically with postal code rules
See which postal codes actually cause trouble, ranked by how often
Checkout page guesses a customer's address from roughly where they are, and the guess is often wrong — most damagingly the postal code. Because the field looks filled in, customers type their city over the top without noticing, and the order ships to the wrong place.
This app gives you two ways to stop that. Switch off autofill for the fields you don't trust, so customers enter them themselves — the postal code alone is usually enough, and street autocomplete keeps working. Or write correction rules that fix the city and region for a postal code range automatically.
Every correction is tracked in your dashboard, and postal codes where checkout couldn't fill in a region are flagged so you can see exactly which ones cause trouble before deciding what to add.
Turning autofill off is included with the Unlimited plan. Correction rules are available on every plan.
