The Postal Service has set Dec. 17 as the recommended last day to mail USPS Ground Advantage packages that need to arrive before Christmas. Priority Mail follows on Dec. 18, and Priority Mail Express on Dec. 19, according to the agency’s 2026 holiday shipping announcement.
The deadlines matter most for anyone mailing cookies, candy or a care package of homemade food, since sweets are easy to send and hard to replace once a date is missed. Here are the dates, the exceptions and a few rules for mailing food.
The 2026 recommended mailing dates
The USPS announcement, dated Sept. 22, lists recommended mailing dates for delivery before Dec. 25 within the contiguous 48 states:
- USPS Ground Advantage: Dec. 17.
- First-Class Mail: Dec. 17.
- Priority Mail: Dec. 18.
- Priority Mail Express: Dec. 19.
The agency’s advice is to send mail and packages early. The dates are recommendations, not promises of delivery, and the further in advance a package goes into the system, the more room there is for delays.
Alaska, Hawaii and the territories
Packages that cross long distances follow different rules. For First-Class Mail, Priority Mail and Priority Mail Express, the dates for Alaska, Hawaii, Puerto Rico and the other territories are the same as above: Dec. 17, Dec. 18 and Dec. 19.
Ground Advantage is the exception. Packages between the contiguous states and Alaska, Hawaii, American Samoa, Puerto Rico, the Virgin Islands, Guam, the Northern Mariana Islands or the Freely Associated States have an expected service time of 10 or more days, according to the announcement. There is no single deadline, because “days will vary due to the range of distances between locations.” Senders can check expected times on the agency’s service commitments tool at usps.com.
For military and international mail, the release points readers to the agency’s holiday shipping page rather than listing dates.

Why December 17 is the cutoff for ground mail
The Postal Service handles its heaviest volume between Thanksgiving and Christmas. Wikipedia’s article on the agency says that stretch is the busiest time of the year, with 11.7 billion packages and pieces of mail handled in 2022. In fiscal year 2025, the agency delivered 108.7 billion pieces of mail and packages to 170.4 million delivery points.
That scale explains why ground service gets the earliest cutoff. Slower service tiers need more days in transit, and the last week before Christmas leaves little slack.

Protecting packages once they arrive
Getting a package to a porch on time is only part of the job. Recipients who are away from home can read about things never to do with holiday packages left on the porch, and about free Post Office options that protect holiday mail, from Hold Mail to Informed Delivery.
For senders, the practical step is to give the recipient a heads-up so food does not sit outside. A message with the expected delivery day is often enough.
Rules for mailing food gifts
Food adds a second deadline on top of the calendar: how long it stays good in transit. The agency’s Publication 52 defines perishable matter as “anything that can deteriorate in the mail.” Mailable perishables go at the sender’s risk, and they must be packaged as required and delivered within appropriate and reasonable time limits to prevent deterioration.
The publication’s section on fresh foods says fresh fruits and vegetables are nonmailable unless they are dry, and that other perishable foods that decompose easily or cannot reach their destination without spoiling are nonmailable. Packaging must meet the requirements in the Domestic Mail Manual sections cited there.
In plain terms, sturdy baked goods such as shortbread, dry cookies and hard candy travel better than cream-filled pastries. Choosing a faster service tier near the deadline gives anything perishable a shorter trip.
Fruitcake is a classic example of a food built to travel. According to Wikipedia’s fruitcake article, mail-order fruitcakes began in America in 1913, and Collin Street Bakery in Corsicana, Texas, is one of the best-known American bakers. Traditional versions are soaked in liqueur or brandy and dusted with powdered sugar, which helps prevent mold, and cakes with a lot of alcohol can keep for many years.
Most home bakers are mailing something less durable. For boxes of cookies or candy, a good packing plan matters as much as the recipe, and a sturdy tin keeps contents from shifting in transit.
The Postal Service lists the dates by service, and the order is easy to remember: ground and First-Class come first, then Priority Mail a day later, then the express tier a day after that.
- Dec. 17: last recommended day for Ground Advantage and First-Class Mail to the contiguous 48 states.
- Dec. 18: last recommended day for Priority Mail.
- Dec. 19: last recommended day for Priority Mail Express.
- Dec. 25: the delivery target for all of them.
Anyone sending food should aim well before these dates, since the dates are the last days for ordinary mail and not the best days for baked goods. Mailing early in the week and early in December keeps cookies fresher and gives time to fix problems if a label is wrong or a box is damaged.
