About the AddressFence: PO Box Guard
AddressFence replaces retired Shopify Scripts with checkout-native address validation. Block PO Box, APO/FPO/DPO addresses, and parcel lockers including Amazon Locker, Packstation, and Japan pickup counters at checkout without adding theme code.
Create ZIP and postal code rules by country using exact match, prefix, range, or wildcard patterns. Set up region-based rules with exceptions for precise control over where you ship.
Test addresses in the built-in simulator before publishing changes. Every rule update is versioned for one-click rollback if needed. The app fails closed, blocking checkout when rules can't be read instead of skipping validation to protect your shipping requirements.
Launched: June 22, 2026
