Many people use PO Boxes to receive mail safely. A PO Box is a small locked box inside a post office. You can rent it to receive letters and packages. But can you ship packages to a PO Box? This is a common question. 

Here, we will explain everything about it. We will talk about which carriers allow PO Box delivery, how to handle a missing package, common problems while using a PO Box, and more.

What Is a PO Box?

A PO Box stands for Post Office Box. It is a secure mailbox inside your local post office. You can rent it monthly or yearly. Those who object to mail delivery to their house use PO Boxes. 

If you live in a distant place or travel frequently, they also come in really handy. With a PO Box, you can collect your mail anytime, whenever the post office is open. It is safe and private.

Why Do People Use a PO Box?

There are many reasons people use a PO Box. Some people live in places where mail service is not reliable. Others don’t want to share their home address. Some business owners also use PO Boxes to receive business mail separately. 

A PO Box is private and secure. This gives you more control over your mail. Depending on the post office hours, you might possibly get it early in the morning or late in the evening.

Can All Packages Be Sent to a PO Box?

The short answer is no. Not all packages can go to a PO Box. It depends on the delivery company and package size. USPS delivers to PO Boxes. But FedEx and UPS usually don’t unless using a special service. 

Big or heavy items may not fit. When that occurs, the post office can keep it for pickup or forward it back to the sender. Before shipping, always double-verify.

Can You Receive Packages at a PO Box?

Actually, a PO Box allows you to get packages, but the carrier will decide this. USPS delivers to PO Boxes without any problem. FedEx and UPS usually don’t deliver to them. That’s because PO Boxes don’t have a street address. 

Some packages will arrive easily. Others may not, unless the delivery service allows for PO Box addresses. Before you order, always verify the shipping method.

Size and Weight Limits for USPS

USPS limits mailpieces by weight and size. The weight limit is 70 pounds. The size limit is 108 inches in total length plus girth. Some services allow 130 inches. Box sizes vary. 

The XL box (Size 5) is about 12 × 22.5 × 14.75 inches. It holds several medium parcels. If your parcel is larger than the box, it will still arrive. But you pick it up at the counter or locker.

What’s the Right Format for a PO Box Mailing Address?

Using the proper address format is necessary. In the first line, start with your entire name. Write “PO Box” on the second line, then the box number. In the third line, record the city, state, and zip code. 

Cut out unnecessary words like “suite” or “mailbox.” This confuses some carriers. Keep things straightforward and clear.

How to Know If a Website Ships to PO Boxes?

Many websites show if they deliver to PO Boxes. During checkout, some sites block the order or show a warning. Others let you choose USPS or split delivery. 

Before you buy, always review the delivery policies of the shop. If it states “No PO Boxes,” you can rely on another address or contact customer service for help. This saves time and avoids delivery issues.

What If a Shipping Company Doesn’t Deliver to PO Boxes?

When a company does not ship to PO Boxes, your delivery might be delayed or returned. Many websites show an error if you enter a PO Box. Some couriers need a street address. 

In such cases, use your home or work address. Or ask the seller to ship with USPS. USPS can deliver to PO Boxes without any issues. This helps avoid delivery problems.

What to Do If You Can’t Ship to a PO Box?

You should not panic if a supplier cannot send to a PO Box. From your post office, try addressing using a street-style address. Find out from a friend or relative whether you might use their house address. 

You can also use a package receiving service. An alternate choice is UPS Access Point or Amazon Locker. Your package can be delivered and subsequently picked up at these secure locations.

How to Handle a Missing Package?

Sometimes, packages to a PO Box may be delayed. First, check the tracking number. If it shows delivered, go to your post office. Show your ID and ask the staff. 

If the package was too big, they might be holding it. If a private carrier sent it, contact them. They may need more time or a street address for delivery.

Is There an Additional Fee for PO Box Deliveries?

Usually, there are no extra charges if you use USPS. Some online sellers may charge a small fee for PO Box delivery. This happens if the package needs special handling or redirection. 

Some companies avoid PO Boxes to avoid these costs altogether. To save money, check the store’s FAQ first. Read the shipping page before you check out.

Common Problems When Using a PO Box

Sometimes, you may face problems with PO Box deliveries. Your package can be returned if it’s too big or wrongly addressed. Couriers may mark it “undeliverable” if the address is unclear. 

Missing the PO Box number or using the wrong ZIP Code causes delays. Always check your shipping details. Make sure the format is correct and the method fits PO Box rules.

PO Box vs. Home Address for Packages

Your needs will decide which of a PO Box or a house address you need. A PO Box protects shipments from theft and provides privacy. 

If you live with others or travel frequently, it’s great. Still, for all couriers, including UPS and FedEx, a home address is simpler for delivery. Choose the one that’s best for your delivery requirements and way of life.

Conclusion

Though only with the right carrier, shipping to a PO Box is possible. USPS is the best and most reliable option. Private carriers like UPS and FedEx usually don’t deliver to PO Boxes. Sometimes, they pass the package to USPS. 

Always check the shipping method before ordering. Write your PO Box address clearly. Use USPS when in doubt. It’s easy, safe, and free of tension. You can use these ideas to make sure your delivery comes on time.
