Understanding how home values differ across Idaho Falls zip codes gives buyers and sellers a meaningful edge. While overall market trends tell part of the story, micro-market variations by neighborhood can be substantial.
83401 — East Idaho Falls
The 83401 zip code covers much of east and northeast Idaho Falls, including access to the Ammon border. Median prices here are among the highest in the city, driven by newer construction and strong school district access. Expect median prices in the $360K–$440K range.
83402 — Central and North Idaho Falls
Zip 83402 covers the central and north Idaho Falls area, including the historic north end prestige neighborhoods. A wide price range exists here — from modest homes in need of updating to premium north end properties well above $600K.
83404 — West Idaho Falls
The west side offers the most accessible price points in the city, with many homes in the $210K–$310K range. This is the primary hunting ground for first-time buyers and investors seeking yield.
83405 — Ammon (Bonneville County)
The Ammon zip codes show strong appreciation driven by Bonneville School District access and newer housing stock. Median prices track the broader Ammon range of $340K–$470K with premium subdivisions pushing higher.
Note: Zip code data is useful for trend analysis but imprecise for individual property valuation. A street-level CMA is far more accurate for pricing or negotiation decisions.
Using Zip Code Data Strategically
Buyers can use zip code trends to identify areas with the strongest recent appreciation — a proxy for neighborhood momentum. Sellers should resist using zip averages to price their homes; actual comparables within a smaller radius are always more precise.
