Miami Beach, FL

ZIP code 33139 is assigned to Miami Beach, FL, and falls within Miami-Dade 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 34,406 people live inside it.

At 12,367 residents per square mile spread over 2.782 square miles, 33139 reads as a dense urban area. It is a populous 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.

Household earnings run below the national median. At $63,368, 33139 sits in the lower half, ahead of 38% 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.

Housing in 33139 costs well above the national median. A typical home is valued at $480,500 against a US median of $207,500, and median gross rent runs $1,745 a month. This is firmly renter territory — 66.1% 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 larger apartment buildings of twenty units or more, which account for 48.8% of housing units here. The median construction year is 1969, making the housing here mid-century. The vacancy rate of 35.1% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews broadly in line with the national age profile, with a median age of 42.1 against 42 nationally. Households average just 1.76 people, and 55.2% consist of one person living alone — a signature of areas with a lot of studio and one-bedroom stock.

Getting to work takes 25.3 minutes on average one way. The dominant mode is drove alone at 42.5% of workers, while 12.9% walk, 20.4% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 33139 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, 33139 offers a compact profile of Miami Beach: 34,406 residents, a median household income of $63,368, 53.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 3.4%. 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. 33139 may cover parts of several distinct areas, and a single neighbourhood in Miami Beach 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.
