This comes after the USPS reported a net loss of $9.5 billion this year, over $3 billion more lost than the year before.

“Over 80% of our current year net loss is attributed to factors that are outside of management’s control,” according to the department.

Priority Mail and Priority Mail Express services will increase their prices by 3.2%, and USPS Ground Advantage prices will be up by 3.9%. Parcel Select services, which apply to large-volume shipping, will see the largest price hike at 9.2%. The agency attempted to increase the price of its parcel service by 25% but failed.

While these increases were voted on by the USPS Board of Governors, the Postal Regulatory Commission has yet to review the change. The commission’s approval will be the final step to make the price hikes official.

In May, the USPS raised the price of stamps from 68 cents to 73 cents. Stamp sales and shipping prices help fund the Postal Service, as it does not receive tax dollars toward its operating expenses. The stamp hike alone will result in an anticipated $44 billion in revenue by 2031.

Last year, first-class mail was at its lowest volume since 1968 at just over 45 billion pieces of mail shipped. This year, first-class mail decreased again to 44 billion, but shipping and packages increased by over 100 million.
