Running a business always comes with unexpected expenses, and it’s important to take advantage of cost-cutting tactics wherever possible. Shipping is one of those areas that can easily put you in the red if you don’t know the tricks to keep your costs down, and one of the best ways to do that is by using USPS boxes free of charge.

What boxes can I get for free from USPS?

You may already know that anyone shipping a package through USPS can walk into a post office, pick up a free Priority Mail® envelope or box, and pay a flat rate to ship it. But are post office shipping boxes free for businesses as well?

The answer is yes, you can pick up free boxes at the post office. What’s more, you can order USPS boxes free online. Not ALL of their boxes are free, however. Here’s a rundown on what boxes and envelopes you can get free online from the U.S. Postal Service.

How to get USPS boxes free?

If you’re looking for free boxes and envelopes for your business, they are available. Can you pick up free boxes at the post office? Yes, you can. But there is an easier way! You can order both boxes and envelopes online and have them delivered to your place of business in packs of 10, 20, or 25, depending on what you’re ordering.

What are the restrictions?

One thing to keep in mind when you’re ordering your free USPS boxes is they must be used as intended. You are obligated to pay Priority Mail shipping costs if you’re using Priority Mail boxes, for example. The shipping service is tied to the packaging.

The good news is that these are all fast shippers, and when you subtract the cost of packaging, it brings down the overall cost of some of the most reliable shipping in the industry. Free boxes solve half the cost equation; postage is the other half.

Priority Mail is delivered in 1 to 3 business days. Domestic boxes have a weight limit of 70 pounds, and if you’re not using a Flat Rate box, the cost is tied to the weight and delivery zone. For Flat Rate you pay a flat fee to ship the package no matter the weight – but you can’t exceed the 70-pound limit.

You can use Priority Mail for international delivery as well, but the weight limits change to 4 pounds for Flat Rate Envelopes, the Small Flat Rate Box, the DVD Box, and the Large Video Box. The weight limit for international delivery is 20 pounds for the Medium and Large Flat Rate boxes.

Priority Mail Express has a next-day to 2-day delivery with a money-back guarantee. You can ship packages up to 70 pounds domestically. The weight limit for Flat Rate Envelopes is 4 pounds for international delivery.
