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.
