If you’re starting an e-commerce business and trying to determine your shipping strategy, you may be wondering: are USPS boxes and envelopes free? Shipping costs, including the money spent on packaging materials, can have a big impact on your bottom line. In fact, 68 percent of businesses listed cost of shipping as their biggest operational challenge, according to our State of Shipping report.

To help business owners manage their shipping costs, the USPS provides free shipping boxes and envelopes for some of their popular service levels.

Here are a few tips to help you take advantage of U.S. Postal Service’s free boxes, envelopes, and shipping supplies.

How Can I Get Free USPS Boxes?

You can order free boxes and envelopes online at the USPS store. The Postal Service will even deliver the supplies to your door for free. Most boxes will typically come in packs of 10 or 25, so keep that in mind as you complete your order. When you select your quantity, you’re choosing how many packs (of 10, 25, etc.) you want. You can also pick up free supplies at your local Post Office.

Are There Any Restrictions to Keep in Mind?

The service level on the packaging must match the service level on the label. So, if you’re shipping the package via Priority Mail Express, you need to use a Priority Mail Express box. You cannot use these boxes for service levels like Media Mail or First-Class.
