Overview

Understanding ZIP code 06231

ZIP code 06231 is assigned to Amston, CT, and falls within Capitol Region 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 3,645 people live inside it.

At 233 residents per square mile spread over 15.657 square miles, 06231 reads as a small-town 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 here sit well above the national picture. The median household income of $159,844 places 06231 in the upper reaches of American postal codes, ahead of 97% 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 Amston looks like

Housing in 06231 costs well above the national median. A typical home is valued at $377,400 against a US median of $207,500, and median gross rent runs $1,553 a month. Ownership dominates: 92.5% 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 94.1% of housing units here. The median construction year is 1984, making the housing here from the later twentieth century.

The population skews older than the national median, with a median age of 45.4 against 42 nationally. The average household holds 2.68 people, and 77.6% are family households.

Getting to work takes 33.7 minutes on average one way. The dominant mode is drove alone at 65.7% of workers, while 21.1% 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 Amston, CT

Amston is a smaller community, so options inside 06231 may be limited to a handful of independent inns, motels or bed-and-breakfast properties. Travellers often widen the search to the surrounding area, where the choice is greater and prices are usually competitive.

Median rent in 06231 is $1,553 a month, which sits in the middle of the national range; accommodation pricing locally tends to be similarly mid-market. For reference, Boston, MA is about 83.9 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.

Practical uses

What ZIP code 06231 is used for

Beyond addressing mail, 06231 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, 06231 offers a compact profile of Amston: 3,645 residents, a median household income of $159,844, 53.5% of adults holding a bachelor's degree or higher, and an unemployment rate of 5.1%. 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. 06231 may cover parts of several distinct areas, and a single neighbourhood in Amston 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.

These are rules of thumb rather than official designations — the Census Bureau classifies urban and rural areas by census block, not by ZIP code.

Accommodation in and around Amston, CT ranges with the character of the area. See the 'Where to stay' section on this page for local context, and use the live search there for current availability and pricing.
Does 06231 cover more than one city or county?
This page lists Amston as the primary place and Capitol Region 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 06231 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.
