As of this writing: No.
President Donald J. Trump signed an Executive Order on December 18, 2025, to provide additional days off for select workers on the following dates:
"All executive departments and agencies of the Federal Government shall be closed and their employees excused from duty on Wednesday, December 24, 2025, and Friday, December 26, 2025, the day before and the day following Christmas Day, respectively," President Donald J. Trump signed. "The heads of executive departments and agencies may determine that certain offices and installations of their organizations, or parts thereof, must remain open and that certain employees must report for duty on December 24, 2025, or December 26, 2025, or both, for reasons of national security, defense, or other public need."[1]
Since the USPS is part of the United States federal government as an independent agency of the executive branch, the Postmaster General could enforce this Executive Order at any moment.
Be that as it may, the "USPS Holiday Service Schedule" doesn't list December 24, 2025, and December 26, 2025, as its closure dates.
"Local Post Office locations will be open. Remember to check your local Post Office for specific hours," the USPS informed. "Regular mail will be delivered."[2]
If I were the Postmaster General, I wouldn't close the USPS on these dates, because it would be chaotic to deal with three days' worth of mail on Saturday.
