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.
