About Mighty PO Box Blocker
Say goodbye PO Box issues!
Do you primarily ship with FedEx, UPS or DHL?
If so, PO Box Blocker is an amazing solution for you! This app warns customers against using PO Box addresses, saving you time and money.
How does it work?
Whenever a PO Box address is detected, a warning is displayed on the cart view and/or the shipping method step of checkout. The warning informs customers that your store does not ship to PO Box addresses and instructs them to specify a valid residential or commercial address instead. You can fully customize the warning messages via the dashboard.
- Email notifications to the merchant and/or customer
Because this app utilizes Shopify's carrier service feature for the warning during checkout, you must meet one of the following requirements to enable the feature:
- Advanced Shopify plan or higher
- Shopify plan is paid annually
- Development store
If none of the requirements are met, you can contact Shopify Support to enable the carrier calculated shipping feature for $20/month - this fee is waived if you opt for annual billing.
We are always adding new features and enhancements based feedback from merchants. Please reach out to us if you have any suggestions!

Amazing support team, they jumped on a call to provide support and helped with the install process.
Thank you for your review. I checked into our application flow and everything is working fine on our end.
However, it may be case of a slow network / congestion on server that could've missed some API for the installation flow.
Please try removing the application from your store and re installing it.

It is a great app and I love it, It saved me more than 1000 USD in shipping to PO BOXES.
Some customers still placing orders with the PO BOX warning so it would be great if the app has a feature to send the mail notifications for these orders.
We can cancel those orders and ask customers to provide physical addresses.
