Overview
Understanding ZIP code 63133
ZIP code 63133 is assigned to Saint Louis, MO, and falls within St. Louis 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 6,375 people live inside it.
At 1,958 residents per square mile spread over 3.256 square miles, 63133 reads as a suburban 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 are well below the national median. At $36,927, 63133 ranks among the lower-income postal codes, ahead of 4% 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 Saint Louis looks like
Housing in 63133 costs well below the national median. A typical home is valued at $59,200 against a US median of $207,500, and median gross rent runs $1,009 a month. The split between owning and renting is fairly even at 45.2% 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 79.4% of housing units here. The median construction year is 1953, making the housing here mid-century.
The population skews broadly in line with the national age profile, with a median age of 38 against 42 nationally. The average household holds 2.21 people, and 46.2% are family households.
Getting to work takes 25.5 minutes on average one way. The dominant mode is drove alone at 78.1% of workers.

Practical uses
What ZIP code 63133 is used for
Beyond addressing mail, 63133 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, 63133 offers a compact profile of Saint Louis: 6,375 residents, a median household income of $36,927, 11.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 6.0%. 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. 63133 may cover parts of several distinct areas, and a single neighbourhood in Saint Louis 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.
