Address Validation App for Checkout. Block PO Boxes, Missing House Numbers and Special Characters

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 PO boxes, missing house numbers, missing apartment numbers, special characters, emojis and zip codes you don't ship to.
