As part of its 10-year plan for achieving financial stability, the United States Postal Service (USPS) is raising the prices of stamps once again on July 9th. The cost to send a postcard, international mail and business metered mail is going up as well. 

The cost of a single stamp rises from 63 cents to 66 cents, metered mail goes from 60 cents to 63 cents, and postcards will increase from 48 cents to 51 cents. Postcards and letters sent internationally are also subject to a 5 cent increase — going from $1.45 to $1.50. 

“Even with postage rate increases, USPS prices will remain among the world’s most affordable and offers a great value in shipping,” the Postal Service said.

It’s unclear whether this will be the only price hike this year. The Postal Service said in its filing with the Postal Regulatory Commission (PRC), which had to approve the price increase, that it is “continually reviewing our pricing approach for all products.”

“With full implementation, the 10-year plan reverses a projected $160 billion in losses over the next 10 years,” the Postal Service said.

Price increases on mail are not the only way the Postal Service intends to meet its goal of reversing $160 billion in losses. It’s also investing in infrastructure and technology to achieve its goal. That includes facility upgrades to promote efficiency and modernizing its delivery fleet.

“Judicious price increases paired with investment in our network will allow us to provide the predictable, reliable service that the American people expect and deserve,” the Postal Service said.
