AddressCleanup adds address autocomplete and a deliverability check to your Shopify Plus checkout. As a buyer types their delivery address, it suggests real addresses and fills in the street, postcode and city when one is picked. Before the order is placed, it checks the address is deliverable and can warn the buyer or block an undeliverable address, based on the strictness you set. It fails open, so if the address service is slow or unreachable, the buyer is never blocked.

• Address autocomplete in the native checkout fields
• Deliverability check warns or blocks undeliverable addresses at checkout
• Works in the countries you enable, with strong Nordic support
