Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBroken German delivery addresses are expensive. A Packstation without the DHL Postnummer or a street without a house number means DHL returns the parcel and you pay shipping twice plus support effort. Address Guard checks German shipping addresses directly in Shopify Checkout using Shopify Functions. Customers see a clear error on the exact field before the order is placed.
Most stores pay one app to stop bad addresses, another to upsell at checkout, and a third to survey buyers. That is three bills and three scripts in one checkout. This app does all three. Block PO Box, Postfach and Packstation addresses in 10+ languages, require a house number, and restrict zip codes, countries, or order values. Add one-click upsell offers from a collection or your best sellers.
