ZipGuard hides specific shipping rates based on the customer's zip or postal code, so you stop fulfilling orders you can't deliver and protect your margins. Built on Shopify Functions (WebAssembly), it works on ALL plans (Basic, Advanced, and Plus) with no checkout UI extension. It runs natively inside checkout with no slow-downs and no flicker. Setup takes seconds: enter restricted zip codes, choose the shipping rate to hide, and save.

• Works on every Shopify plan: Basic, Advanced, and Plus. No UI extension needed.
• Runs on WebAssembly, filtering shipping rates natively inside Shopify checkout.
• Block any zip code, postal code, or region from choosing a shipping rate.
