A Seasonal Mountain Community

Avon, Colorado sits in Eagle County's high country, serving as the postal gateway to Beaver Creek Resort. With a population of 10,038, this is one of the most populated PO Box-classified ZIPs in the nation. But that number only tells part of the story. Of the 8,299 housing units, 3,643 are used seasonally (44%), meaning the population swells dramatically during ski season and shrinks in the off-months.

Why PO Boxes Outnumber Homes

The Avon post office maintains 4,756 PO Boxes for 3,938 year-round households. This 1.21 adoption rate isn't just about residents. It's about second-homeowners who need a mailing address for properties they visit a few weeks each year, seasonal workers who rotate through ski season, and resort businesses managing mail for multiple locations. Beaver Creek is recognized as an official mailing name for this ZIP, and the street with the most delivery points is W Beaver Creek Blvd (631 addresses).

Resort-Town Economics

Median home values reach $951,800, and median household income is $99,152. These aren't typical small-town Colorado numbers. They're resort-town numbers. The community spreads across 96.8 square miles of mountainous terrain, mixing town addresses (2 city carrier routes) with rural mountain properties (2 rural routes). Street names tell the alpine story: Wildridge Rd, Swift Gulch Rd, Bachelor Gulch Trl, Elk Track Ln.

Who Lives Here Year-Round

The age distribution is unusual. Median age is 36.7 years, but there are only 263 residents under 18. This is a working community, not a family town. With 19.7% of workers doing their jobs from home, it's also a place where people can ski during the day and work remotely. Only 52% of occupied homes are owner-occupied, with the rest rented to seasonal workers or used as short-term vacation rentals.

Mail in the Mountains

This isn't a PO Box Only Zone. Street delivery exists throughout the community. But when you own a $950,000 ski condo you visit three weeks a year, maintaining a PO Box makes more sense than hoping packages sit outside in mountain weather. That's why boxes outnumber households here.
