About ZIP Code 27599

The University of North Carolina at Chapel Hill, the oldest public university in the United States, operates under dedicated ZIP code 27599 in Orange County, North Carolina. Chartered by the North Carolina General Assembly on December 11, 1789, the university laid its cornerstone on October 12, 1793. The first student, Hinton James from what is now Pender County, arrived on February 12, 1795, remaining the sole student for two weeks until classmates joined him. William Richardson Davie, a Revolutionary War military officer and future governor, is recognized as the Father of the University. Old East, constructed for $5,000 in 1793, remains in use as a residence hall and is the oldest building originally constructed for a public university in the nation.

The postal boundary encompasses approximately 0.07 square miles at the heart of Chapel Hill in the Raleigh-Durham metropolitan area. This ZIP serves one of the largest and most complex campus mail operations in the state, with postal records identifying 721 ZIP+4 codes serving 635 named buildings and departments. Mail reaches locations including Wilson Library, the Ackland Art Museum, multiple academic departments, administrative offices, and research facilities. This extensive building directory reflects an institution that employs thousands and serves over 30,000 students.

The 2020 Census counted just 16 residents within this ZIP boundary, with a median age of 21.7 years. The small residential count indicates that this ZIP primarily covers administrative and academic buildings rather than dormitories, with student housing captured by surrounding Chapel Hill ZIP codes. The USPS has maintained this dedicated designation for over two decades. Chapel Hill is the valid mailing city.
