The Benefits of Having a P.O. Box

P.O. Boxes provide three significant benefits: security, safety, and flexibility.


P.O. boxes help ensure that your mail and packages are safe at the post office and only you or other people you specify can pick up your items.


A P.O. box can help keep your home address and important documents confidential for peace of mind.


P.O. boxes allow you to receive mail on your preferred schedule, with various sizes and rental periods, such as 3, 6, or 12 months.

Negatives of Having a P.O. Box

Despite the benefits P.O. boxes offer, these boxes have a few disadvantages, discussed in the following sections.

P.O. Boxes Are Inconvenient

P.O. boxes are associated with a specific post office location. If you live or work far from that location, you must travel during most days to check your mail in that box.

Moving your home or business address can create further inconvenience because you must fill out another set of forms, pay new fees, and wait for another confirmation in the mail.

Also, you’re locked into a specific P.O. box rental period, meaning you may pay extra if you cancel early.

P.O. Boxes Have Limited Mail and Package Receiving Capability

Private shipping companies usually don’t deliver to a USPS P.O. Box. So if you or your senders prefer any of these companies, you likely can’t use a P.O. Box to receive mail or packages from these shippers.

Also, some of your mail may not fit inside if you order an extremely small P.O. box. In this case, you can receive a note in your box to retrieve your mail at the service counter or get a key to a larger storage box.

The Future of the P.O. Box Is Already Here

Virtual addresses, sometimes called virtual P.O. boxes, allow you to receive mail like a physical P.O. box but without stepping into a post office.

One feature of virtual addresses is that instead of checking your box daily, an automated system scans your packages or mail and digitally delivers the image to your digital mailbox.

How Much Does Renting a P.O. Box Cost?

As of June 2023, the USPS P.O. Box costs to rent per month are as follows:

  • Size 1 (XS): Starts at $4.50

  • Size 3 (M): Starts at $8.67
  • Size 4 (L): Starts at $12.83
  • Size 5 (XL): Starts at $22.50

Upon receiving your application, the Postal Service personnel will determine your eligibility and input your data into the company’s web box activity tracking system (WebBATS). This online application lets retail staff manage P.O. box inventory.
