Checkout Address Validator

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.Rules are set per country, and buyer messages ship in 33 languages.
