See every featureB2B buyers ship to multiple locations — and managing that through emails, support tickets, or a single checkout field doesn't scale. This app gives buyers a structured address book per company location: save, edit, and select from stored addresses at checkout, with temporary one-time entries kept separate.
Zip Block Pro – Block checkout by zip code. Add zip codes to an exclusion list in the app. At checkout, if the customer’s shipping zip is on that list, the order is blocked and they see: “We cannot ship to [zip]. Please use a different address.” How it works: Enter the zip codes you want to block (comma-separated), save, then enable the app under Settings → Checkout → Checkout rules. No code or theme changes.
- Manage multiple reusable shipping addresses per B2B company location.
- Let buyers choose the correct shipping address during checkout.
- Support temporary checkout addresses without cluttering the saved list.
- Keep saved, temporary, and default addresses clearly organized.
- Enter blocked zip codes (comma-separated) and save. No code or theme edits.
- Block checkout when the shipping zip code is on your exclusion list.
