FP1 ‑ Postcode Shipping Guard

Block Postcode/Postal/ZIP codes at checkout. Stop orders to restricted regions.

FP1 - Postcode Shipping Guard blocks restricted Postcode, Postal Code, and ZIP Code areas without changing your Shopify shipping zones. Block exact codes, use * to cover wider areas (such as SW1A*), or enter postcode ranges using a dash (such as 1000-1999). When a checkout address matches a saved rule, available shipping methods are removed until the postcode changes. Manage rules directly in the app with no coding required, and optionally show shoppers a cart notice before checkout.

• Block restricted Postcode/Postal/ZIP codes inside your shipping zones.
• Block exact codes, wildcard areas (SW1A*), or postcode ranges (1000-1999).
• Apply rules globally or restrict a rule to a specific country.
• Manage rules in the app—no editing shipping profiles or zones required.
• Optional cart notice (theme app block) to set expectations before checkout.
