About NoBox: PO Box Blocker
NoBox prevents failed deliveries by blocking orders with PO Box addresses at checkout. It detects all common PO Box formats in both address fields and lets merchants add their own custom blocking keywords. The app also blocks restricted ZIP codes, postal code ranges, cities, states, countries, and military addresses. For international merchants, it detects PO Box equivalents in six languages. Specific products or variants can be exempted from all blocking rules. Error messages are customizable.
