FP1 ‑ Postcode Shipping Guard

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

Keep your Shopify shipping zones and block restricted Postcode/Postal/ZIP codes with simple rules. Block one code exactly, or block an area using * (example: SW1A*). When a rule matches at checkout, no shipping methods are shown, so the order can’t proceed until the address changes. Manage rules in-app with no coding. Optional cart notice. Typical support reply in 30 minutes for non-escalations. 14-day free trial and first-month refund on request within 30 days of first charge.

• 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.
