Courier services generally can't deliver to a PO box the way national postal mail can — here's what that actually means and what to do about it.
A PO Box (Post Office Box) is a mail-only address operated by a national postal service, designed to receive letters and small postal packages — not a physical street address a courier vehicle can drive to. This is a structural difference, not a policy choice: DHL, UPS, FedEx, DPD and GLS all require a physical delivery address with a real street location, because their networks are built around door-to-door vehicle delivery, not the postal sorting-office model that makes PO Boxes work for mail.
Courier networks are built around physical delivery — a driver with a specific street address to navigate to and a recipient to hand the parcel to or leave it with. A PO Box is just a numbered slot inside a post office, accessible only by postal staff sorting mail into it. There's no door for a courier to knock on and no street address for a delivery vehicle to route to, which is why this is a structural limitation rather than something that varies by carrier or can be requested as an exception.
The simplest fix is asking the recipient for a real street address — their home, workplace, or a friend's address — rather than their PO Box. Most people who use a PO Box for mail privacy or because they move frequently still have a physical address they can provide for parcel delivery specifically.
If a street address genuinely isn't available, many countries have parcel locker networks or courier collection points (a local shop or depot that accepts deliveries on the recipient's behalf) that function similarly to a PO Box but do have a real physical address a courier can deliver to. Ask whether the recipient's country has this kind of service available near them.
No — none of the major courier networks can deliver to a PO Box, since it's a mail-sorting slot inside a post office rather than a physical street address a delivery vehicle can route to. This applies across all major couriers, not just some.
National postal services sort mail directly into PO Boxes as part of their own internal sorting process at the post office. Courier networks operate a completely different model — vehicle-based delivery to a physical street address — which a PO Box, by definition, doesn't have.
Ask them for a real street address instead — home, workplace, or a trusted contact's address. If that's genuinely not possible, ask whether a parcel locker or courier collection point is available near them as an alternative.
No, though they serve a similar convenience purpose. Parcel lockers have a real physical street address that couriers can deliver to, unlike a PO Box, which is only accessible through the postal service's internal sorting system.
