Marble is a small Iron Range community in Itasca County, Minnesota, where 504 residents rely on PO Boxes as their only mail option. It's a PO Box Only Zone.

The town sits about 6 square miles in Minnesota's iron mining country. The "Greenway" alias (recognized by USPS but not valid for mailing) points to the town's connection with the Greenway mining district. Streets here carry women's names: Alice Avenue, Kate Street, Jessie Street, Harriet Street, and Ethel Street. This naming pattern was common in Iron Range mining towns from the early 1900s.
Marble's housing stock tells its history. Of the 246 housing units, 214 were built before 1939, when iron mining dominated the regional economy. The median home value of $101,500 and median rent of $708 keep housing affordable. Most residents own their homes (163 owner-occupied versus 52 renter-occupied).
The workforce leans heavily toward transportation and warehousing (222 workers), with educational services and healthcare employing another 96. Only 4.8% of adults hold a bachelor's degree or higher, and 22% work from home. Median household income runs $63,417, near the national median. This is a working-class community where the post office remains the sole point of mail access for everyone.
Street names use women's first names, typical of early Iron Range mining town planning.
