Overview
Understanding ZIP code 06401
ZIP code 06401 is assigned to Ansonia, CT, and falls within Naugatuck Valley 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 19,160 people live inside it.
At 3,180 residents per square mile spread over 6.026 square miles, 06401 reads as a densely built-up area. It is a mid-sized 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 $80,953 puts 06401 near the middle of the pack, ahead of 66% 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 Ansonia looks like
Housing in 06401 costs close to the national median. A typical home is valued at $268,400 against a US median of $207,500, and median gross rent runs $1,405 a month. The split between owning and renting is fairly even at 58.8% 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 53.7% of housing units here. The median construction year is 1954, making the housing here mid-century.
The population skews broadly in line with the national age profile, with a median age of 39.8 against 42 nationally. The average household holds 2.56 people, and 64.5% are family households.

Where to stay in Ansonia, CT

Practical uses
What ZIP code 06401 is used for
Beyond addressing mail, 06401 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, 06401 offers a compact profile of Ansonia: 19,160 residents, a median household income of $80,953, 22.9% of adults holding a bachelor's degree or higher, and an unemployment rate of 8.0%. 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. 06401 may cover parts of several distinct areas, and a single neighbourhood in Ansonia 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.
