Delivering to USA PO Boxes Direct with USPS (Even During a Canada Post Strike)
How Canadian shippers can continue delivering to USPS PO Boxes during a Canada Post disruption using Jet Worldwide’s US handoff to USPS workflow—plus alternatives, timelines, and FAQs.
Understanding the Challenge of Delivery to PO Box Addresses
During a postal service disruption like a Canada Post strike, not only are domestic deliveries affected—so are international shipments that would normally route through Canada Post, including those destined for USPS PO Boxes. Because only the United States Postal Service (USPS) can deliver to PO Boxes in the USA, a strike in Canada requires an alternate path to reach the USPS network.
How Can I Ship to a USPS PO Box in the USA During a Canada Post Strike?
- Check for a street address first. If your recipient has no alternate street address, use a USPS handoff.
- Use a courier to the USA (door-to-door) and inject into USPS for last-mile PO Box delivery.
- Have Jet Worldwide issue a prepaid USPS label (Priority Mail or Priority Mail Express) and handle the transfer.
Once your details are confirmed, your package travels by courier to our US facility and is tendered to USPS within ~2 business days for final delivery to the PO Box.

Canada Post Alternative Delivery Options
When you don’t need PO Box delivery, private couriers like FedEx, UPS, and DHL offer reliable service to US street addresses (same for returns). They often provide faster transit and enhanced tracking—but usually at a higher price point than Canada Post small-packet services.
