ZIP code 46556 serves the University of Notre Dame campus in St. Joseph County, Indiana. This isn't a town. It's a 0.59 square mile campus where 8,845 people live in just 275 household units, creating a population-to-household ratio of 32.2 to 1. That number tells the story: 8,267 residents (93.5% of the population) live in noninstitutionalized group quarters, which means student dormitories.
Mail delivery at Notre Dame works through a building-based system across 177 named campus locations. Students receive mail at residence halls like Grace Hall, Brownson Hall, and Jenkins Nanovic Hall. The campus post office maintains 109 PO Boxes and operates 57 distinct city carrier routes that deliver to academic buildings, athletic facilities, convents, and administrative centers. The PO Security Building handles 86 delivery records with unit designators, serving as a central mail processing point.
Key campus buildings receiving mail include:
The median age is 20.4 years. These are college students. The census shows only 4 residents under 18 and just 1 person aged 65 or over. With 70.5% of the population holding a bachelor's degree or higher, Notre Dame stands among the most educated ZIPs in America. The campus employs 14,996 people across 42 business establishments, though many employees commute from surrounding South Bend neighborhoods like Keller Park and Northshore Triangle.
While classified as a PO Box ZIP by USPS, Notre Dame actually operates extensive street delivery infrastructure. The classification doesn't match current operations. This isn't a PO Box Only Zone, and carrier routes serve buildings from the iconic Main Building and Hesburgh Library to newer facilities like Stinson Remick Hall and Duncan Student Center. The campus includes not just Notre Dame buildings but also Saint Mary's College facilities like Le Mans Hall and Holy Cross Hall SMC.
The campus population is 79.9% white, 6.9% Asian, 4.2% Black, and 4.4% two or more races, with 2.9% Hispanic or Latino. Per capita income reaches $7,526, though this figure doesn't capture the economic reality of a student population. What it does show is a residential campus where students live, study, and receive mail at their dormitory addresses rather than maintaining off-campus PO Boxes.
