Mapleton, UT

ZIP code 84664 is assigned to Mapleton, UT, and falls within Utah 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 12,340 people live inside it.

At 1,234 residents per square mile spread over 10.001 square miles, 84664 reads as a suburban 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 here sit well above the national picture. The median household income of $127,860 places 84664 in the upper reaches of American postal codes, ahead of 93% 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 84664 costs far above the national median. A typical home is valued at $734,100 against a US median of $207,500, and median gross rent runs $1,392 a month. Ownership dominates: 87.0% 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 97.2% of housing units here. The median construction year is 2004, making the housing here relatively modern. At 2.0%, vacancy is low — housing here is tightly held.

The population skews younger than the country as a whole, with a median age of 31.4 against 42 nationally. Households are relatively large at 3.63 people on average, with 90.5% classified as family households.

Getting to work takes 24.7 minutes on average one way. The dominant mode is drove alone at 68.6% of workers, while 17.9% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 84664 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, 84664 offers a compact profile of Mapleton: 12,340 residents, a median household income of $127,860, 54.0% of adults holding a bachelor's degree or higher, and an unemployment rate of 3.0%. 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. 84664 may cover parts of several distinct areas, and a single neighbourhood in Mapleton 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.
