As of my knowledge cutoff in 2023, the United States Postal Service (USPS) typically observes the following holidays:

According to the USPS holiday schedule, Veterans Day (November 11th) is indeed a federal holiday, which means that mail delivery will be suspended on November 11th, 2023.

However, please note that this information is subject to change, and it's always a good idea to check with your local post office or the USPS website for the most up-to-date information on holiday hours and mail delivery schedules.
