Guidelines when Using a Box to Ship USPS

The Box Appearance

When using or reusing a box to ship with USPS you will need to remove previous labels, address details, etc.

If there are barcodes on the box these will need to be covered up or removed as they could cause issues with the USPS scanners.

If the box has logos or images that are associated with prohibited items, (toxic materials, firearms, etc), the box will be taken out of circulation by USPS.

Even if the contents being shipped is not on the prohibited list.

The Size of the Box

USPS has a wide scope on the sizes of the boxes that they will ship. However, there is a maximum size rule.

As of 2022, USPS will not ship a box larger than 108 inches in total length and girth, (unless you are using USPS Retail Ground or Parcel Select).

If your box exceeds these dimensions, you will not be able to use most USPS services for shipping.

The Shape of the Box

What is the shape of the box? While irregularly shaped boxes are allowed to be shipped via USPS, you may incur extra fees if extra care has to be taken by USPS due to the shape of the box.

This is due to irregularly shaped boxes potentially causing issues in the sorting and scanning machines.

This technology is designed for normal cuboid or rectangular-shaped packages.

Is the Box Strong Enough?

This is actually a factor that the shipper should be comfortable with before shipping.

The box you use needs to be sturdy enough so that the contents arrive at their destination safely. 

The last issue you should want to encounter is hearing that the box split in transit and the contents are sprawled across two states.

When using your own box, make sure it is up to the shipping task.

The best way to ship USPS Priority Mail is to use the flat rate boxes. These are free from USPS (at the post office or when ordered online) and will guarantee you the flat rate prices.

Can I Use Any Box To Ship USPS First Class?

USPS does not provide boxes for First Class so you are expected to use your own boxes.

Following the same guidelines above, you can use any box to ship USPS first class. 

However, bear in mind the service has a weight limit of 13oz. So, although you can use any box the overall weight of the shipment cannot exceed this.

Can I Use Any Box To Ship Internationally With USPS?

USPS has Priority Mail International Flat Rate boxes available. As with USPS domestic Priority Mail, it is recommended that you use these so that you can access the flat rate prices.

However, you can use any box to ship internationally with USPS. Furthermore, using your own box you can ship via USPS services such as Global Express Guaranteed, Priority Mail Express International, Priority Mail International and First-Class Package International.

The box you use definitely needs to be strong and secure to meet the demands of international shipping. 

To help customers, USPS has published guidelines on the requirements here.
