The U.S. Postal Service will increase stamp prices starting Sunday, a USPS representative confirmed to "Good Morning America."
The cost of first-class stamps will rise from 66 cents to 68 cents for letters weighing one ounce or less.
Package shipping costs will also increase by nearly six percent, with Priority Mail Express costs going up by 5.9 percent, Priority Mail increasing by 5.7 percent, and Ground Advantage going up 5.4 percent.
The price hikes, the fifth increase in two years, are part of the Postal Service's ten-year "Delivering for America" plan to raise rates and recover from plunging profits – a projected $160 billion loss over the next ten years

Those areas will see an increase of more than nine percent, prompting lawmakers like Alaska Sen. Dan Sullivan to speak out.

"These hikes have the potential to severely negatively impact Alaskans – already reeling from inflation – who are more reliant on the USPS for basic goods and services than other Americans."
