Overview

Understanding ZIP code 83643

ZIP code 83643 is assigned to Mesa, ID, and falls within Adams 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 165 people live inside it.

At 47 residents per square mile spread over 3.483 square miles, 83643 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.

Living here

What life in Mesa looks like

Housing in 83643 costs well above the national median. A typical home is valued at $472,700 against a US median of $207,500. Ownership dominates: 76.9% of occupied homes are owner-occupied, which usually signals an established residential area with relatively low turnover.

The building stock is dominated by detached single-family houses, which account for 97.0% of housing units here. The median construction year is 1990, making the housing here from the later twentieth century. The vacancy rate of 35.0% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews considerably older than the national median, with a median age of 61.4 against 42 nationally. The average household holds 2.54 people, and 52.3% are family households.

Getting to work takes 62.4 minutes on average one way. The dominant mode is drove alone at 100.0% of workers.

Where to stay

Where to stay in Mesa, ID

83643 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, Seattle, WA is about 348.4 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 83643 is used for

Beyond addressing mail, 83643 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, 83643 offers a compact profile of Mesa: 165 residents, 14.6% 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. 83643 may cover parts of several distinct areas, and a single neighbourhood in Mesa 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.

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.
