Overview

Understanding ZIP code 04021

ZIP code 04021 is assigned to Cumberland Center, ME, and falls within Cumberland 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 6,629 people live inside it.

At 323 residents per square mile spread over 20.547 square miles, 04021 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 $145,833 places 04021 in the upper reaches of American postal codes, ahead of 96% 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 Cumberland Center looks like

Housing in 04021 costs well above the national median. A typical home is valued at $506,800 against a US median of $207,500. Ownership dominates: 93.4% 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 92.7% of housing units here. The median construction year is 1981, making the housing here from the later twentieth century. At 4.8%, vacancy is low — housing here is tightly held.

The population skews broadly in line with the national age profile, with a median age of 38.9 against 42 nationally. The average household holds 2.87 people, and 82.7% are family households.

Getting to work takes 28.6 minutes on average one way. The dominant mode is drove alone at 66.5% of workers, while 26.1% 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 Cumberland Center, ME

Cumberland Center is a smaller community, so options inside 04021 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.

For reference, Boston, MA is about 106.7 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 04021 is used for

Beyond addressing mail, 04021 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, 04021 offers a compact profile of Cumberland Center: 6,629 residents, a median household income of $145,833, 69.6% of adults holding a bachelor's degree or higher, and an unemployment rate of 2.8%. 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. 04021 may cover parts of several distinct areas, and a single neighbourhood in Cumberland Center 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 04021 cover more than one city or county?
This page lists Cumberland Center as the primary place and Cumberland County as the county.

If you need the definitive answer for a specific street address, the USPS ZIP Code Lookup is the authority.
Can ZIP code 04021 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.
