USPS Sets 2026 Holiday Mailing Deadlines: December 17 to 19 at Home, Earlier for Military and International Mail
The U.S. Postal Service has published its recommended send-by dates for delivery before Christmas Day 2026, urging the public to allow time for cards and gifts. The dates below are USPS's recommended deadlines; actual delivery depends on origin, destination and when the item is accepted.
For the contiguous United States: USPS Ground Advantage and First-Class Mail (cards and letters) should be sent by December 17; Priority Mail by December 18; and Priority Mail Express by December 19. The same First-Class and Priority dates apply for Alaska, Hawaii, Puerto Rico and U.S. territories.
Mail to military addresses (APO/FPO/DPO) closes earlier: for the Europe (AE) ZIP ranges, First-Class Mail and Priority Mail are recommended by December 9, and Priority Mail Express Military Service by December 16; Ground Advantage for some ranges closed on November 4.
For international destinations, First-Class Package International and Priority Mail International are recommended by December 9, and Priority Mail Express International by December 16.
USPS also notes that Hanukkah runs December 4 to 12 in 2026, so cards and gifts for those dates need an earlier mail day. The full table by destination category is on the Postal Service's holiday shipping page.
