Description

Validates German checkout addresses: Packstation needs a Postnummer, streets need a house number.

Broken 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. No external servers are involved and address data never leaves Shopify. International addresses pass through untouched.
