Overview

Understanding ZIP code 83111

ZIP code 83111 is assigned to Auburn, WY, and falls within Lincoln County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 307 people live inside it.

At 20 residents per square mile spread over 15.025 square miles, 83111 reads as a rural area. It is a sparsely populated postal code, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.

Household earnings here sit well above the national picture. The median household income of $125,438 places 83111 in the upper reaches of American postal codes, ahead of 93% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Living here

What life in Auburn looks like

The building stock is dominated by detached single-family houses, which account for 78.7% of housing units here. The median construction year is 1992, making the housing here from the later twentieth century. At 0.0%, vacancy is low — housing here is tightly held.

The population skews older than the national median, with a median age of 50.9 against 42 nationally. Households average just 1.98 people, and 20.6% consist of one person living alone — a signature of areas with a lot of studio and one-bedroom stock.

Getting to work takes 29.5 minutes on average one way. The dominant mode is drove alone at 100.0% of workers.

Where to stay

Where to stay in Auburn, WY

83111 covers a rural area, and accommodation within the postal code itself is likely to be sparse — perhaps a country inn, a lodge or a vacation rental rather than a conventional hotel. Widening the search radius is usually the practical approach, and it also opens up more availability at short notice.

For reference, Denver, CO is about 378.0 miles away in a straight line, which is worth factoring in if you are comparing a stay here against one closer to the city centre.

Practical uses

What ZIP code 83111 is used for

Beyond addressing mail, 83111 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.

For anyone weighing a move, 83111 offers a compact profile of Auburn: 307 residents, a median household income of $125,438, 0.0% of adults holding a bachelor's degree or higher, and an unemployment rate of 0.0%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.

One caution worth repeating: a postal code is not a neighbourhood. 83111 may cover parts of several distinct areas, and a single neighbourhood in Auburn may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.

Does 83111 cover more than one city or county?
This page lists Auburn as the primary place and Lincoln County as the county.

If you need the definitive answer for a specific street address, the USPS ZIP Code Lookup is the authority.
Can ZIP code 83111 change?
Yes. USPS adjusts ZIP codes as delivery volumes shift — codes are occasionally split, merged, retired or newly created, and boundaries move more often than most people assume. The Census Bureau's ZCTA definitions, which underpin the demographic figures on this page, are redrawn only once a decade, so the two can drift apart between censuses.

On accuracy. ACS figures are survey estimates, not counts. The margin of error shown alongside the population figure means the true value has a 90% chance of falling in that range. For small ZIP codes the error can be large relative to the estimate — treat the direction as more reliable than the exact number.
