A number of U.S. Postal Service products, including the Forever stamp, will cost more starting Sunday.

That stamp, now at 68 cents, will start costing 73 cents.

Stamps for domestic 1-ounce letters will go from 64 to 69 cents, postcards from 53 to 56 cents, and both international postcards and international 1-ounce letters from $1.55 to $1.65.

The price of additional ounces for single-piece letters will rise from 24 cents to 28 cents.

“The USPS consistently blames frequent postage hikes on inflation, but … rate increases are consistently far and above the Consumer Price Index. Across the board, the proposed July price increases hover at an average of 6.53% above inflation, which is 1.622%,” Kevin Yoder, a former Republican congressman from Kansas and now executive director of the advocacy group Keep US Posted, said in April when the USPS proposed the price increases.

The hike is the sixth in the past two years and comes as the USPS continues to operate at a deficit, with a net operating loss of $2.3 billion in fiscal 2023, according to the Postal Regulatory Commission.
