Overview

Understanding ZIP code 52557

ZIP code 52557 is assigned to Fairfield, IA, and falls within Jefferson 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 615 people live inside it.

At 2,303 residents per square mile spread over 0.267 square miles, 52557 reads as a suburban 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 Fairfield looks like

Getting to work takes 16.0 minutes on average one way. The dominant mode is worked from home at 37.7% of workers, while 31.4% walk, 37.7% 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 Fairfield, IA

Fairfield is largely suburban in character. Accommodation here skews toward mid-range chain hotels and extended-stay properties positioned near highway junctions and business parks, which suits anyone driving in or visiting for work rather than sightseeing.

For reference, Chicago, IL is about 232.2 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 52557 is used for

Beyond addressing mail, 52557 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, 52557 offers a compact profile of Fairfield: 615 residents, 80.7% of adults holding a bachelor's degree or higher, and an unemployment rate of 20.5%. 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. 52557 may cover parts of several distinct areas, and a single neighbourhood in Fairfield 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 52557 cover more than one city or county?
This page lists Fairfield as the primary place and Jefferson 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 52557 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.
