ZipGuard lets your customers check delivery availability before placing an order. Add a zip code input field directly on the product page — if the entered pin code isn't serviceable, the Add to Cart button is automatically disabled, preventing failed orders and customer frustration. Easily manage your list of serviceable zip codes from the admin panel. Reduce returns, improve delivery accuracy, and give customers a clear, upfront experience — no checkout surprises.

• Block Add to Cart for undeliverable zip codes stop invalid orders at the source
• Real-time pin code validation on the product page before customers add items.
• Manage serviceable zip codes easily from your Shopify admin — no coding needed.
