FP1 ‑ Postcode Shipping Guard

FP1 - Postcode Shipping Guard blocks restricted Postcode, Postal Code, and ZIP Code areas without changing your Shopify shipping zones. Block exact codes or use * to cover wider areas, such as SW1A*. 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.
