AddressPill: Address Validator

AddressPill validates shipping addresses before and after checkout. Warn or block missing house numbers, PO boxes, Packstations, special characters, duplicate names, email typos, and custom patterns. After purchase, verify real addresses, apply safe corrections, let customers fix issues on the order status page, tag or hold affected orders, and trigger notifications with Shopify Flow. Configure 25 customer-facing languages and keep checkout non-blocking when preferred.
