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.

• Blocks checkout when a postal code or house number is missing
• Validates express wallet checkouts: Shop Pay, PayPal, Apple Pay, Google Pay
• Every country you ship to, with Shopify's postal-code rule prefilled
• P.O. boxes, packstations and pickup points are never blocked
• Buyer messages in 33 languages, editable for every store language
