Overview
Understanding ZIP code 04109
ZIP code 04109 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 188 people live inside it.
At 151 residents per square mile spread over 1.241 square miles, 04109 reads as a rural 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 Portland looks like
Housing in 04109 costs far above the national median. A typical home is valued at $717,700 against a US median of $207,500. Ownership dominates: 100.0% 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 100.0% of housing units here. The median construction year is 1938, making the housing here largely pre-war. The vacancy rate of 69.1% is high, which in many places reflects seasonal or second-home use rather than abandonment.
The population skews considerably older than the national median, with a median age of 73.1 against 42 nationally. Households average just 1.84 people, and 28.4% consist of one person living alone — a signature of areas with a lot of studio and one-bedroom stock.
Getting to work takes 39.2 minutes on average one way. The dominant mode is public transit at 42.3% of workers, while 42.3% take public transit, 32.7% 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 Portland, ME
04109 covers a rural area, and accommodation within the postal code itself is likely to be sparse — perhaps a country inn, a lodge or a vacation rental rather than a conventional hotel. Widening the search radius is usually the practical approach, and it also opens up more availability at short notice.
For reference, Boston, MA is about 99.5 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 04109 is used for
Beyond addressing mail, 04109 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, 04109 offers a compact profile of Portland: 188 residents, 87.6% of adults holding a bachelor's degree or higher, and an unemployment rate of 0.0%. 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. 04109 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.
