Mighty PO Box Blocker will stop customers from being able to input PO Boxes as shipping addresses which saves you time and money having to work issues out after the purchase. Whenever a PO Box address is detected, a PO Box Blocker warning is displayed on the cart view and/or the shipping method step of checkout. The warning tells customers that your store does not ship to PO Box addresses and instructs them to specify a new valid residential or commercial address instead.

• Block PO Box addresses that FedEx, UPS, and DHL do not deliver to.
• Optimized design for both desktop and mobile devices.
• Create fully customized warning messages that find your brand.
• PO Box Blocker pop ups to warn customers they need to input a new address.
