USPS holiday shipping deadlines 2026 are out, and the last dates to ship for delivery before Christmas are December 17 for USPS Ground Advantage and First-Class Mail, December 18 for Priority Mail, and December 19 for Priority Mail Express. These are USPS's recommended send-by dates for the lower 48 states, published September 22, 2026. They are recommendations, not guarantees, so treat them as the last safe day, not the day to aim for.
USPS holiday shipping deadlines 2026 at a glance
| USPS service | Ship by (lower 48) | Best for |
|---|---|---|
| USPS Ground Advantage | Thursday, Dec. 17 | Most ecommerce orders, the cheapest option |
| First-Class Mail | Thursday, Dec. 17 | Cards, letters, flat envelopes |
| Priority Mail | Friday, Dec. 18 | Orders that need 1 to 3 day delivery |
| Priority Mail Express | Saturday, Dec. 19 | Last-minute orders, the fastest USPS option |
USPS targets delivery before Christmas Day, Friday, December 25. The dates above assume the package is accepted by the Post Office in time. USPS notes that actual delivery can vary with origin, destination, and acceptance time, so a package dropped off late in the day on December 17 may not move until the next day.
Alaska, Hawaii, and US territories
First-Class Mail, Priority Mail, and Priority Mail Express keep the same dates as the lower 48: December 17, 18, and 19. Ground Advantage is the exception. USPS gives no fixed date for Ground Advantage to Alaska, Hawaii, Puerto Rico, and the territories, and says to allow 10 or more days in transit. If you ship Ground Advantage to those destinations, send it by early December at the latest and check the expected delivery date on USPS.com for the specific ZIP code.
International and military mail close earlier
International deadlines land much sooner than domestic ones. First-Class Package International and Priority Mail International close Wednesday, December 9. Priority Mail Express International closes Wednesday, December 16. Military mail to APO, FPO, and DPO addresses closes earliest of all: Ground Advantage to military addresses closed Wednesday, November 4. If you still have international orders in the queue, upgrade the service or warn the buyer that Christmas delivery is no longer expected.
Hanukkah is early this year
Hanukkah runs December 4 to December 12 in 2026, which is earlier than most sellers expect. Gift orders for Hanukkah need to ship in late November or the first days of December, well before the Christmas deadlines above. If you sell items that work as Hanukkah gifts, set a separate, earlier cutoff for those listings and say so on the listing itself.
Turn the carrier dates into your store cutoff
The carrier's last day is not your last day. Your store cutoff has to land earlier, because the buyer orders, you pack, and then the carrier takes over. A simple rule: subtract your handling time from the carrier date.
Worked example: you sell mugs, your handling time is 2 business days, and you ship Ground Advantage. The carrier date is Thursday, December 17. Two business days of handling means the last order you can accept for Christmas delivery is Tuesday, December 15, and that assumes you pack and drop off the same day. With a 1 day handling time, the cutoff moves to Wednesday, December 16. Set the cutoff in your shop announcement and on the listing, so buyers see it before they order.
Two more things to build into your cutoff calendar. First, weekends: December 19 is a Saturday, and Priority Mail Express is the only service with a weekend deadline. Second, your local Post Office acceptance cutoff. A package handed over after the daily cutoff counts as the next business day, so confirm your local cutoff time in December, when lines are longest.

Size your boxes before the holiday rush
Holiday shipping costs more when the box is wrong. Oversized boxes trigger dimensional weight pricing, and the wrong box size can push a Ground Advantage parcel into a higher price tier. Use our free box size calculator to find the smallest box that fits each product and the dimensional weight carriers will charge on, before you set your holiday rates.
USPS holiday dates change every year. The dates in this guide follow USPS's published 2026 holiday shipping dates, verified November 13, 2026, so confirm the current dates on USPS.com before you publish a cutoff to your customers.
