## What you need to know

### How does autocomplete differ from validation?

Autocomplete offers suggestions as a shopper types a delivery street. Validation may flag a missing unit or unusual postal code; it should allow the customer to review or correct the address, not block submission entirely.

### What if the address appears invalid?

Explain what looks wrong without wiping the form. Give a way to edit it or continue when a real address is not recognized and the shipping process allows that choice.

### How should countries differ?

Postal codes, regions and address order vary by country. Test a country-specific layout for each destination served, rather than requiring a format that only works for one country.

### A quick store check

Test a standard address, an apartment address and a legitimate address the validator questions. Confirm the buyer can review and correct the result without losing previously entered information.

## Frequently asked questions

### Can lookup guarantee delivery?

No. Suggestions and validation can be wrong or incomplete; the shopper and fulfilment process still need a way to resolve an unusual address.

### Where are address settings?

Use verified checkout documentation, then test supported country formats and manual corrections before publishing.
