Keep reading to find out the best way to ship a parcel to a PO box.

In the past, PO boxes were mostly used to receive mail when an address wasn’t within the delivery range of the postal service, usually from people who lived in remote areas and couldn’t receive regular mail service directly at their house. Nowadays, people use them for several reasons.

Location: The postal service doesn’t deliver to all addresses, so people use a P.O. box to receive their mail.

Privacy: Using a P.O. box you have the privacy of your home address. This can be very useful when you want to separate your personal and business mail.

Delivery speed: Due to their location, receiving mail at a P.O. box is faster than at your home address.

Security: A P.O. box is located within a postal office and is locked, therefore offering more security than a regular mailbox at a private house or an office.

When can courier companies deliver to PO box addresses?

One of the most frequently asked questions from shippers all over the world is whether there are couriers that deliver to PO box addresses. If you are one of them, you should know that courier services providers usually do not deliver to PO boxes, for the following reasons:

  1. Couriers are supposed to track the pickup and delivery of the parcel, as well as the time and the date. A courier delivery to a PO box wouldn’t allow this, as there would be no one to sign upon the driver’s arrival.
  2. Courier companies need a valid postal address in order to deliver the parcel.
  3. PO boxes are mostly linked to postal services, which means the shipping service is not carried out by a courier company, but rather from the national post service.

Nevertheless, there are some exceptions of couriers that do deliver to PO box addresses in certain parts of the world, such as USA, France, Croatia, Greece, Iceland, Portugal and in the Middle East region.


So why don’t all the couriers deliver to PO boxes?

Some courier companies, such as UPS or FedEx, can deliver to PO Box addresses under certain conditions and within certain countries. For instance, if the phone number of the receiver is included on the shipping label, the courier can call the consignee and arrange the delivery in an alternative location. Some courier providers may even deliver directly to PO boxes whenever they have special agreements with local or national postal offices.
