This depends on the mail carrier the brand uses for shipments. If the brand uses USPS to ship, using a P.O. Box as your shipping address may be fine. You can go ahead and enter your PO Box shipping address as long as you don't see an error message. If for whatever reason the brand is not able to ship your order to the PO Box provided, our Customer Service Team will reach out to you for an alternative address.
If the brand does not use USPS to ship packages and you enter a P.O. Box as your shipping address, you will see an error message saying that the product can't be delivered to that address. Neither the brand nor Pantastic will be able to make an exception in this case.
