How much does it cost to mail a letter to Hawaii from the continental U.S. (otherwise known as the mainland)?
First, a little history. Hawaii became a state in 1959. We are not merely a territory or a possession (those involved in the sovreignty movement may disagree, but that has no bearing on postage issues). Therefore, the postage to Hawaii follows normal U.S. Postal Service regulations — right now, it’s 37 cents for a 1-ounce letter.
