Overview
Understanding ZIP code 83427
ZIP code 83427 is assigned to Iona, 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 2,819 people live inside it.
At 34 residents per square mile spread over 83.256 square miles, 83427 reads as a rural area. It is a smaller 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 track close to the national picture. The median of $82,418 puts 83427 near the middle of the pack, ahead of 68% 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 Iona looks like
Housing in 83427 costs well above the national median. A typical home is valued at $368,400 against a US median of $207,500, and median gross rent runs $1,284 a month. Ownership dominates: 92.1% 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 85.7% of housing units here. The median construction year is 2003, making the housing here relatively modern.
The population skews notably young, with a median age of 29 against 42 nationally. Households are relatively large at 3.49 people on average, with 83.5% classified as family households.
Getting to work takes 21.8 minutes on average one way. The dominant mode is drove alone at 81.0% of workers, while 11.2% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.
Where to stay
Where to stay in Iona, ID
83427 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.
Median rent in 83427 is $1,284 a month, which sits in the middle of the national range; accommodation pricing locally tends to be similarly mid-market. For reference, Denver, CO is about 429.7 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 83427 is used for
Beyond addressing mail, 83427 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, 83427 offers a compact profile of Iona: 2,819 residents, a median household income of $82,418, 27.9% of adults holding a bachelor's degree or higher, and an unemployment rate of 1.0%. 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. 83427 may cover parts of several distinct areas, and a single neighbourhood in Iona 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.
