The U.S. Post Office is set to raise the price of Forever stamps, the second increase in a year.

USPS filed a notice Monday with the Postal Regulatory Commission outlining plans to raise the price of a Forever Stamp by 3 cents starting July 9th. The proposed price is 66 cents, up from the current price of 63 cents.

“The proposed increases will raise First-Class Mail prices approximately 5.4 percent to offset the rise in inflation. The price changes have been approved by the Governors of the U.S. Postal Service,” USPS said in a statement.

The price to send a domestic postcard will increase to 51 cents; a 1-ounce letter mailed to another country would go to $1.50. The price for a single-piece letter and flat additional-ounce price remains at 24 cents.

Earlier this year, the price of a Forever Stamp increased to 63 cents from 60 cents. Before that, stamp prices last increased in July 2022 when they jumped to 60 cents from 58 cents after prices rose by 3 cents in August 2021.
