FP1 ‑ Postcode Shipping Guard

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

FP1 - Postcode Shipping Blocker lets you keep your existing Shopify shipping zones while blocking restricted Postcode/Postal/ZIP areas with simple rules. Block an exact code, or use * to block a wider area, such as SW1A*. When a matching address is entered at checkout, no shipping methods are shown, so the order cannot proceed until the address changes. Manage rules in-app with no coding. Optional cart notice included. 14-day free trial, then $5.99/month.

• Block restricted Postcode/Postal/ZIP codes inside your shipping zones.
• Block exact codes, or block a whole area using * (for example, SW1A*).
• 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.
