New postage rates go into effect on May 12

The price for a one-ounce First-Class stamp will increase from 41 to 42 cents on May 12. Prices for other mailing services, such as standard mail, periodicals, package services (including single-piece parcel post) and special services will also change (see chart below). The average increase by class of mail is at or below the rate of inflation as measured by the Consumer Price Index.

"The Postal Service developed the Forever Stamp for consumers to ease the transition during price changes," said Postmaster General John Potter. "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 5 billion Forever Stamps since the launch last April and plans to have an additional 5 billion in stock to meet the expected demand before the May price change.
