ZipSentry: Address Validator

Validate shipping addresses at checkout. Stop failed deliveries before they ship.

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
