ZIP code 37315 serves Southern Adventist University in Collegedale, Tennessee. This isn't a town. It's a campus. Of the 1,760 residents, 95% live in group quarters, primarily student dormitories. The median age of 21.7 years confirms this is a college community.
The campus occupies just 0.007 square miles in Hamilton County, about 15 miles east of Chattanooga. Mail delivery occurs almost entirely to one address: University Dr W, which has 135 delivery points with secondary unit designators. The post office maintains 449 PO Boxes for a community with only 39 occupied housing units. That's an adoption rate of 11.5 to 1.
Why so many boxes for so few residents? The university employs 5,973 people across 28 establishments, making it one of Tennessee's largest educational employers. Students, faculty, staff, and the surrounding community all rely on this post office. The extreme PO Box count shows this ZIP serves far beyond its tiny geographic footprint.
This is a PO Box Only Zone. There's no alternative mail delivery. All residents and university personnel must use either campus mail distribution or PO Boxes. The classification makes sense: with 95% of the population in dormitories, individual carrier routes aren't practical.
Education levels are high. Among residents 25 and over, 45.9% hold bachelor's degrees or higher. The population is 73% White, 13% Black, 4% Asian, with minimal Hispanic presence. Zero residents own homes; all 39 occupied housing units are rentals, likely faculty or staff housing.
The university dominates employment patterns. Transportation and warehousing account for 901 workers (73% of the employed population), likely reflecting campus logistics and facilities management. Educational services employ 537 workers. Just 116 people (9.4%) work from home, lower than typical college towns where remote work is common.
Per capita income is $3,576, which seems impossibly low but makes sense for students with minimal reported income. Many students work part-time or receive support from family, neither of which shows up in this figure.
