Overview

Understanding ZIP code 83323

ZIP code 83323 is assigned to Declo, ID, and falls within Cassia 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 1,856 people live inside it.

At 9 residents per square mile spread over 203.635 square miles, 83323 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 run below the national median. At $61,696, 83323 sits in the lower half, ahead of 35% 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 Declo looks like

Housing in 83323 costs close to the national median. A typical home is valued at $320,500 against a US median of $207,500, and median gross rent runs $886 a month. The split between owning and renting is fairly even at 66.0% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.

The building stock is dominated by detached single-family houses, which account for 82.0% of housing units here. The median construction year is 1984, making the housing here from the later twentieth century.

The population skews broadly in line with the national age profile, with a median age of 38.3 against 42 nationally. The average household holds 2.73 people, and 82.9% are family households.

Getting to work takes 18.6 minutes on average one way. The dominant mode is drove alone at 84.9% of workers.

Where to stay

Where to stay in Declo, ID

83323 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.

Local costs are modest — median rent here is $886 a month — and accommodation prices in the area tend to be correspondingly reasonable. For reference, Denver, CO is about 478.9 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.

Availability and pricing change constantly, so the live search below will give you a more accurate picture than any figure we could publish here. It opens results for this area on Booking.com.

Practical uses

What ZIP code 83323 is used for

Beyond addressing mail, 83323 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, 83323 offers a compact profile of Declo: 1,856 residents, a median household income of $61,696, 19.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 1.7%. 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. 83323 may cover parts of several distinct areas, and a single neighbourhood in Declo 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 83323 cover more than one city or county?
This page lists Declo as the primary place and Cassia County as the county. ZIP codes follow mail delivery routes rather than municipal or county lines, so a single code can straddle boundaries, and USPS also recognises alternate acceptable city names for many codes. If you need the definitive answer for a specific street address, the USPS ZIP Code Lookup is the authority.
Can ZIP code 83323 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.
