The price of a U.S. postage stamp goes up Monday. It will now cost 44 cents to mail a first class letter. That’s a two cent increase.

Since January 2001, rates for first-class stamps have gone up 10 cents.

The stamps came out on Saturday, but the official start date is May 11th. People will still be able to use their “forever stamps”, which are stamps that are bought at current prices, but can be used regardless of future price changes.

Other mailing prices also went up. For a complete list of price changes, click here.
