The post office operates as the community's mail lifeline. All 115 occupied households rely on PO Box delivery, and there's no alternative. While one rural carrier route technically exists for Yukon Avenue, the practical reality is that residents collect mail at the post office. The building maintains 121 PO Boxes, slightly more than the local household count, serving the immediate community plus a few outlying addresses.
This isn't a failure of infrastructure—it's geography. The ZIP covers 65.79 square miles of remote Alaskan terrain where traditional street delivery doesn't make sense. The median household income is $53,906, and homes have a median value of $23,900. These aren't markers of poverty but reflect the local cost structure and subsistence economy common in rural Alaska.
The community's age distribution shows resilience: median age is 24.7 years, with 35 children under 5, 26 children ages 5-9, and 32 children ages 10-14. That's 93 kids in a population of 492. The post office serves as more than a mail facility—it's a gathering point where residents connect, especially during winter months when river travel becomes challenging.
The post office maintains one General Delivery route alongside the rural route and PO Box service. With only 12 businesses and 4 commercial establishments employing 36 people, this is primarily a residential community. The USPS facility opened before October 2004 and has been serving the area continuously since.
Marshall has minimal street infrastructure with only Yukon Avenue appearing in postal records. This reflects the community's river-oriented layout and reliance on the post office for mail collection rather than home delivery.
ZIP Code 99585 has 492 residents and 115 households (average 4.28 persons per household). The median age is 24.7 years, significantly younger than the state (35.6) and significantly younger than the nation (38.8). The gender split is 52.6% male and 47.4% female, which is higher than the national male share (49.1%), making this a male-majority area. Largest groups are American Indian & Alaska Native (94.3%, much higher than the state average of 15.2% and well above the national average of 1.1%) and White (1.6%, much lower than the state average of 59.4% and well below the national average of 61.6%); Hispanic or Latino residents make up 0.2%, which is much lower than the national average (18.7%), and American Indian & Alaska Native share is much higher than both the state (15.2%) and national averages (1.1%).
