The U.S. Postal Service does not plan to increase the cost of first-class stamps heading into 2025 despite raising some delivery prices.

USPS is expected to raise shipping services prices by approximately 3.2% for Priority Mail and Priority Mail Express, 3.9% for Ground Advantage, and 9.2% for Parcel Select, according to Newsweek.

Postmaster General Louis DeJoy said a price increase could be proposed for first-class stamps later in the year, the outlet reported.

The proposed price increases, which would take effect Jan. 19, were approved by the USPS board of governors and have been filed with the Postal Regulatory Commission for review, The Hill reported.

The new rates require approval from the commission before taking effect.

Shipping service prices are adjusted based on market conditions while mailing service rates are tied to the consumer price index, The Hill added.

The proposed price increases are part of a "Delivering for America" 10-year plan to achieve "financial sustainability and service excellence."

USPS said the rate changes "will support the $40 billion of investments in people, technology, and infrastructure and continue the modernization and improvement of the Postal Service's operations and customer experience,” Newsweek reported.

"As a strategic part of the Delivering for America 10-year plan, these proposed changes will support the Postal Service in creating a revitalized organization capable of achieving our public service mission.”

Some customers may find themselves affected by new USPS delivery times next year.

"Depending on location, time and distance, expected time to deliver will increase for some ZIP code pairs," read a press release from USPS in October.

A USPS spokesperson previously told CBS MoneyWatch that mail should continue to be delivered within the current service standard of two-to-five days, and most mail from rural areas in three days or less, Newsweek reported.

USPS, which receives no tax dollars to help cover operating expenses, relies on postage and product sales to fund its operations.

Congress provides an annual appropriation to compensate the USPS for providing free mailing to the blind and overseas voters. Also, the annual appropriation compensates the USPS for debt accumulated from the 1990s.  In 2023, that amounted to about $50 million.

Earlier, this month USPS announced a partial list of stamps to be released in 2025. They include a Lunar New Year stamp celebrating the Year of the Snake, a stamp for the Appalachian Trail, and a stamp honoring actor Betty White.
