To mail a 9 by 12 envelope within the United States, you typically need two Forever stamps, as the cost for mailing a large envelope (flats) is higher than a standard letter. As of my last update, the rate for a first-class large envelope starts at the price of a single Forever stamp, and additional postage is required for extra weight. Always check the current USPS rates, as they may change.
That all depends on how much is in it. It goes by weight. See the U.S. domestic postage website at the link below. Anyway, it's not about "how many stamps" but "how much postage." Stamps come in denominations from 1 cent on up.
It depends on the weight as it would be processed as "Flat Mail". Visit the Related Link for a chart of the price by oz. from the USPS.
