All Priority Mail sub-services have the same standards, with delivery within 1-3 days, full package tracking, and $100 of insurance included for free.

You can ship any box or envelope with Priority Mail

Priority Mail is the shipping service that USPS advertises the most, and you’ve probably seen the ads for Priority Mail Flat Rate® with the tagline, “If it fits, it ships.”

But because of those commercials, a common misunderstanding is that you have to use a special USPS-branded box. It’s not true!

You can use any type of packaging to ship with Priority Mail and it’s usually much cheaper than using a Flat Rate package.
