AddressPill: Address Validator

AddressPill is an address validator for Shopify stores shipping to Germany, Austria, Switzerland, the US, the UK, Australia, Canada and beyond. In checkout it warns about or blocks missing house numbers, PO boxes, Packstations, special characters and email typos. After purchase, address verification runs on the Thank You and Order Status pages: customers correct their own address, small ZIP and city typos are fixed, and problem orders are tagged, held or sent to Shopify Flow.
