USPS Christmas deadline
The United States Postal Service has announced its cutoff dates for deliveries in time for Christmas.
- December 16 is the cutoff for 5-day shipping using USPS Ground Advantage and First-Class Mail services.
- If you pay for 4-day-shipping, you have until December 18 to mail parcels and have them arrive under the tree by Christmas.
- Consumers have until December 21 if they use the USPS's Priority Mail Express 1-day shipping option.
Keep in mind, the USPS won't be delivering regular mail on Christmas Day. And because Christmas Eve falls on a Sunday this year, the last scheduled day for regular USPS delivery is Saturday, December 23.
For Priority Mail Express mail, if a holiday premium is paid, the last scheduled delivery day is Sunday, December 24.
