Validate and autocomplete shipping addresses to reduce delivery errors and failed orders.
Address Validator checks shipping addresses while buyers are still in checkout. It catches typos, missing unit numbers and invalid postal codes, then offers a one-click corrected address. Autocomplete fills Shopify’s native address fields as buyers type. Delivery rules warn or block PO boxes, missing house numbers, countries or regions. If an order still goes through to a flagged address, the buyer gets an email in your store’s name to enter a new one. Order history records every check.
- Real-time address verification in checkout with a one-click corrected address
- Address autocomplete inside Shopify's native checkout address fields
- Delivery rules: warn or block PO boxes, no house number, countries, regions
- Order history with every address check and the buyer's decision on it
- Email buyers a link to fix an address your rules flagged after the order
