The prices for other mailing services including standard mail, periodicals, package services and special services will also change, according to the Postal Service.
The price to mail a postcard will increase from 26 cents to 27 cents; large envelope, from 97 cents to $1; certified mail, $2.65 to $2.70; first-class international letter to Canada and Mexico, 69 cents to 72 cents; and first-class letter to other countries, 90 cents to 94 cents.
The price of Forever stamps will also rise to 42 cents, the Postal Service announced.
"The Postal Service developed the Forever stamp for consumers to ease the transition during price changes," said Postmaster General John Potter in a prepared statement. "We encourage Americans to buy Forever stamps now for 41 cents, because like the name suggests, they are good forever."
The Postal Service has sold more than five billion Forever stamps since the launch in April.
Consistent with the Postal Accountability and Enhancement Act, prices for mailing services will be adjusted each May, according to the Postal Service.
New prices for shipping services such as Express Mail and Priority Mail will be announced in March. Prices for all postal products and services may be viewed at http://www.usps.com/prices.
