Overview
Understanding ZIP code 04101
ZIP code 04101 is assigned to Portland, 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 18,128 people live inside it.
At 8,939 residents per square mile spread over 2.028 square miles, 04101 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 run below the national median. At $60,726, 04101 sits in the lower half, ahead of 34% 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 Portland looks like
Housing in 04101 costs well above the national median. A typical home is valued at $600,600 against a US median of $207,500, and median gross rent runs $1,457 a month. This is firmly renter territory — 77.4% of occupied homes are rented, a pattern typical of city centres, student areas and neighbourhoods with a lot of apartment stock.
The building stock is dominated by mid-sized apartment buildings, which account for 38.7% of housing units here. The median construction year is 1938, making the housing here largely pre-war.
The population skews broadly in line with the national age profile, with a median age of 36.3 against 42 nationally. Households average just 1.76 people, and 52.9% consist of one person living alone — a signature of areas with a lot of studio and one-bedroom stock.
Getting to work takes 20.8 minutes on average one way. The dominant mode is drove alone at 41.3% of workers, while 23.1% walk, 22.0% 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 Portland, ME
Portland is a built-up area, so you will generally find a mix of chain hotels near the main approach roads and a smaller number of independent properties closer to the centre. Staying in 04101 itself often costs less than an equivalent room in the nearest downtown while keeping you close to it.

For reference, Boston, MA is about 98.7 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 04101 is used for
Beyond addressing mail, 04101 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, 04101 offers a compact profile of Portland: 18,128 residents, a median household income of $60,726, 57.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 3.5%. 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. 04101 may cover parts of several distinct areas, and a single neighbourhood in Portland 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.
