How much postage to mail letter from us to northern mariana islands?

To mail a letter from the U.S. to the Northern Mariana Islands, you typically need to use the same postage as you would for domestic mail, as they are a U.S. territory. As of my last update, a standard first-class letter (up to 1 ounce) requires a stamp of $0.66. However, it’s always advisable to check the latest rates on the USPS website or at your local post office, as postal rates can change.
