About AddressFence: PO Box Guard
Shopify now blocks PO boxes, lockers and ZIP patterns natively, on the shipping address only. AddressFence covers what that leaves out. Billing address: block PO boxes, lockers, ZIP and region on billing - fields the built-in rules cannot target. Street number: the Address Blocker rule that was not migrated. Blocks a street line with no number in it. Plus exceptions, allowlists, exact/prefix/range/wildcard ZIP matching, a simulator, and versioned publishes with rollback.
