Overview
Understanding ZIP code 83406
ZIP code 83406 is assigned to Idaho Falls, ID, and falls within Bonneville 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 19,991 people live inside it.
At 624 residents per square mile spread over 32.027 square miles, 83406 reads as a small-town area. It is a mid-sized postal code by population, 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 run above the national median. At $90,654, 83406 sits comfortably in the upper half, ahead of 76% 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.

Practical uses
What ZIP code 83406 is used for
Beyond addressing mail, 83406 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, 83406 offers a compact profile of Idaho Falls: 19,991 residents, a median household income of $90,654, 36.8% of adults holding a bachelor's degree or higher, and an unemployment rate of 2.7%.

One caution worth repeating: a postal code is not a neighbourhood. 83406 may cover parts of several distinct areas, and a single neighbourhood in Idaho Falls 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.
