Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureAddressVerify checks shipping addresses in checkout and after purchase so bad deliveries get fixed before they ship. Catch missing house numbers, invalid ZIPs, PO Boxes, typos, and incomplete addresses. Suggest corrections, auto-fix when confident, or hold orders for review. Tag orders by error type, track analytics and ROI, and only per unique order with volume-based rates. Fail open by default so checkout stays.
UPS, FedEx, DHL and other couriers can't deliver to PO boxes, so those orders bounce back or need a costly fix. PO Box Shipping Carrier Guard checks the address at checkout and asks for a street address when the chosen shipping option can't reach a PO box. Choose which of your shipping options go by mail, like USPS, and customers can still use a PO box with those. Prefer no PO boxes at all? Block them everywhere.
