Overnight mail service on sunday

In the United States, the United States Postal Service (USPS) does not offer overnight mail service on Sundays. The USPS is closed on Sundays, and mail delivery does not occur on this day.

However, there are some private courier services that may offer Sunday delivery, but this is not a standard service and may incur additional fees. Some of these services include:

  1. FedEx: FedEx offers Sunday delivery in some areas, but it is not a standard service and may require an additional fee.
  2. UPS: UPS offers Sunday delivery in some areas, but it is not a standard service and may require an additional fee.
  3. DHL: DHL offers Sunday delivery in some areas, but it is not a standard service and may require an additional fee.

It's important to note that even if a private courier service offers Sunday delivery, it may not be available in all areas or for all types of packages. It's best to check with the courier service directly to see if they offer Sunday delivery and what the fees may be.

In general, if you need to send a package overnight, it's best to plan ahead and send it on a Friday or Saturday to ensure it arrives on Monday.
