OG ‑ Zipcode Checker

Check pincode and zipcode delivery before checkout to cut RTOs and failed orders. OG Zipcode Checker is a Shopify pincode and zipcode validator for delivery serviceability. Upload serviceable postal codes by CSV or manually, then show a storefront widget on product and cart pages so customers verify delivery availability, COD eligibility, estimated delivery days, and return windows before ordering. Block add-to-cart or checkout for unserviceable areas with a theme app extension - no theme code edits. Includes live widget preview, product tag targeting, and guided onboarding.
