Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureAdd real-time, carrier-validated address verification to checkout - or replace Shopify’s Google Autocomplete with our Autocomplete. Our address validator validates against global and local carriers and uses AI Autocorrection to fix small errors (Rd→Road), prevent failed deliveries, and cut correction fees (many carriers charge $25+). Create rules to block PO Boxes or require apartment numbers.
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.
- Prompt customers to fix addresses when issues are detected and offer suggestions
- Prevent undeliverable addresses by carrier (PO Boxes, Missing house #, etc)
- Automatically “hold” orders that are undeliverable before they get sent to a 3PL
- Improve customer data accuracy with Email & Phone Number Verification
- 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
