Post Office

The Citadel Post Office is a full service Contract Postal Unit sanctioned by the United States Postal Service. Mail service is an integral part of The Citadel as a business, and as a vital link between the campus and a lifeline to the rest of the world. The Citadel Post Office is responsible for the delivery and collection of all United States Post Service, Inter-Agency, and Intra-Campus mail. Our goal is to provide professional and efficient mail service to The Citadel community. We are committed to providing the highest level of service for all your mailing needs.

All cadets and campus residents are eligible to obtain their MSC box to receive mail. MSC (Mail Stop Code) is a postal code used to differentiate our box numbers from those of downtown Charleston. The Citadel has been assigned a unique zip code - 29409. New cadets will be assigned an MSC box prior to their arrival on campus.

We are located on the first floor of Mark Clark Hall, next to the Gift Shop and Barber Shop. Hours of operation are Monday through Friday from 8:30 am to 4:00 pm. Outgoing mail received by 4:00 pm will be dispatched to the United States Postal Service that same day.

We encourage you to browse our website for additional information. Further resources can be located at www.usps.com. Please contact a staff member at The Citadel Post Office for assistance with your questions or any mailing needs at 843-953-7690.
