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.
Express wallets — Shop Pay, PayPal, Apple Pay, Google Pay — skip your address form, so orders arrive with a street but no house number, or no postal code at all, and the delivery fails. A missing house number only produces a warning at checkout, which the buyer can ignore. This app turns it into a block: checkout cannot be completed until the address is fixed, wallets included.
