YES, YOU CAN USE SIGNATURE CONFIRMATION WITH PO BOXES!

FedEx, UPS, and DHL cannot deliver to PO Boxes.

The USPS can.

And, when shipping valuable cargo, you can use Signature Confirmation when shipping to a PO Box.

The Post Office will simply leave a notice inside the PO Box, asking the recipient to wait in line and sign for your package at the Post Office retail counter.

So you can get a "wet signature" proof of delivery.

With TransGuardian, you can print Priority Mail labels (insured up to $150,000) and First Class Mail labels (insured up to $1,000) with Signature Confirmation -- to any destination, including PO Boxes.
