Address Shield is an address validation app. It checks the delivery address at checkout and asks your customer to fix anything wrong before it reaches you. Validation runs inside Shopify's checkout, so addresses are never sent to our servers, never stored and never shared. We never rewrite an address, because auto-correction can turn a correct address into a wrong one.
- Block users when the address contains non-latin or special characters
- Block all PO Boxes with professional checkout validation & address validition
- Block users from checkout without a house number and/or without a street name
- Works on all Shopify stores, not just Shopify+ stores like most other solutions
- Addresses never leave Shopify. Checks run in checkout, nothing is sent to us
- Never rewrites an address. Your customer is asked to fix it, so nothing is lost
- Block missing house numbers, missing apartment numbers and special characters
- Block PO boxes your carriers can't deliver to, and zip codes you don't ship to
