ZipSentry: Address Validator

ZipSentry: Address Validator is a Shopify App that helps ecommerce merchants validate shipping addresses at checkout to prevent failed deliveries. The app allows merchants to set rules such as requiring a house number, blocking P.O. boxes, or validating postal code format. It also provides the option to flag orders for review or block checkout based on the rules set by the merchant. Customers with flagged addresses can correct them on the order status page, and the dashboard provides estimates on how much each catch saved the merchant.
