Land O' Lakes residents hoping a drop a few letters into the mail this morning might want to check their stamps.

The cost of sending out a letter just went up by a penny.

The U.S. Postal Service raised the rate to mail a 1-ounce letter from 45 cents to 46 cents yesterday, Jan. 27.

The good news, however, is anyone who uses a “Forever stamp” won’t have to scramble to get extra postage. Going forward, the new 46-cent Forever stamps will continue to cover postage costs – no matter what price increases come down from Washington, D.C.

“Forever stamps are always good for mailing a one-ounce letter anytime in the future regardless of price changes,” a postal service media release said.

The Postal Service is also introducing a new Global Forever stamp, which will allow you to mail letters anywhere in the world for $1.10.

Here is a breakdown of the new single-piece First-Class mailing prices:

• Letters (1 ounce) — 1-cent increase to 46 cents
• Letters additional ounces — unchanged at 20 cents
• Letters to all international destinations (1 ounce) — $1.10
• Postcards — 1-cent increase to 33 cents
