About ZipSentry: Address Validator

Mistyped and incomplete shipping addresses lead to failed deliveries, refunds, and support tickets. ZipSentry checks every address at checkout against rules you choose, such as requiring a house number, blocking P.O. boxes, or validating postal code format. Each rule can block checkout or flag the order for review, so you decide what is worth stopping a sale over. Flagged customers can correct their own address on the order status page, and the dashboard estimates what every catch saved you. Flag mode tags risky orders for review Block P.O. boxes, missing house numbers, and invalid postal codes at checkout Per-country rules and presets, with checkout messages in 14 languages Show more Show less
