Key Facts
  • The post office maintains 1,731 PO Boxes for just 36 local households, a ratio of 48 to 1 that shows how heavily second homeowners and businesses rely on this facility.
  • Almost 40% of the 63 housing units are used for seasonal, recreational, or occasional use, typical of a high-end ski resort community.
  • This ZIP covers nearly 56 square miles of mountainous Pitkin County terrain, with street delivery available via 2 city routes and 1 rural route.
  • The 335 businesses and 491 employees operating in this ZIP contribute significantly to PO Box demand beyond the tiny permanent population.
  • Street names like Castle Creek Road, Red Mountain Road, and Aspen Mountain Road trace the geography of Aspen's famous ski terrain.
  • Despite being classified as a PO Box ZIP, this isn't a PO Box Only Zone. Street delivery exists, but the mountain landscape makes PO Boxes more practical for many.

A Seasonal Community

Aspen's 81612 ZIP code serves the mountain terrain surrounding one of America's most famous ski destinations. Only 79 people live here year-round, spread across just 36 occupied homes in nearly 56 square miles of Rocky Mountain landscape. But the post office maintains 1,731 PO Boxes, roughly 48 boxes for every local household. That ratio tells you everything about this community.

Why Everyone Needs a PO Box

Second homeowners and seasonal residents drive that extreme PO Box count. Almost 40% of the housing units here are vacation properties, sitting empty most of the year. Owners keep PO Boxes active regardless of whether they're in town. Ski season brings a surge of temporary residents who need mail access during their stays. The 335 businesses in this ZIP, many tied to Aspen's recreation economy, also rely heavily on the post office.

Mountain Roads and Mail Routes

Street names paint a picture of the terrain: Castle Creek Road, Red Mountain Road, Hunter Creek Road, and Conundrum Creek Road wind through the valleys. Aspen Mountain Road climbs toward the slopes. McLain Flats Road crosses the agricultural benchland. Puppy Smith Street handles the bulk of delivery points (761 records), likely representing a concentrated residential or commercial development.

Mixed Delivery Options

Mail delivery here isn't PO Box only. Both city carrier routes (2 routes) and rural routes (1 route) serve the area, delivering to properties that can accommodate street addresses. But with homes scattered across mountainsides and down remote valleys, many residents find a PO Box more practical than waiting for carriers to navigate winding mountain roads.
