The cost of mailing a postcard will go up a penny to 24 cents.

It's part of the more than five-percent, across-the-board increase in U.S. Postal Service rates and fees.

If you have stamps at the old 37-cent rate, there are options, like buying two cent stamps.

There is a Congressional requirement in a bill passed in 2003, requiring the U.S. Postal Service to create a more than $3 billion escrow account.

Congress will decide later how the money will be used.
