(CNN) — The US Postal Service on Friday proposed increased prices “to offset the rise in inflation,” according to a statement from the agency.

The price hikes, which have been approved by the Governors of the U.S. Postal Service, include a three-cent increase to purchase a stamp and a four-cent increase to mail a postcard. The changes amount to a 4.2% price increase for first class mail, according to USPS.

The proposal must now be reviewed by the Postal Regulatory Commission.

The announcement from the US Postal Service comes as consumers around the nation continue to grapple with rising prices for groceries, gas and other necessities. The US Postal Service has publicly struggled financially in recent years, and President Joe Biden signed a law earlier this year to overhaul the USPS’ finances and allow the agency to modernize its service.

“As operating expenses continue to rise, these price adjustments provide the Postal Service with much needed revenue to achieve the financial stability sought by its Delivering for America 10-year plan,” US Postal Service said on Friday. “The prices of the U.S. Postal Service remain among the most affordable in the world.”

Unlike other government agencies, the USPS generally does not receive taxpayer funding, and instead must rely on revenue from stamps and package deliveries to support itself.

The Postal Service is also looking to increase fees for P.O. Box rentals, money orders and the cost to purchase insurance when mailing an item.

If approved by the Postal Regulatory Commission the changes would take effect January 22, 2023, after midnight.
