Fairbanks, AK

ZIP code 99775 is assigned to Fairbanks, AK, and falls within Fairbanks North Star 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 707 people live inside it.

At 1,470 residents per square mile spread over 0.481 square miles, 99775 reads as a suburban 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.

Household earnings track close to the national picture. The median of $71,022 puts 99775 near the middle of the pack, ahead of 52% 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.

The building stock is dominated by small multi-family buildings of two to four units, which account for 68.7% of housing units here. The median construction year is 1977, making the housing here from the later twentieth century. The vacancy rate of 30.3% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews notably young, with a median age of 21.5 against 42 nationally. Households are relatively large at 5.2 people on average, with 86.0% classified as family households.

Getting to work takes 14.6 minutes on average one way. The dominant mode is walked at 67.8% of workers, while 67.8% walk. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 99775 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, 99775 offers a compact profile of Fairbanks: 707 residents, a median household income of $71,022, 87.1% of adults holding a bachelor's degree or higher, and an unemployment rate of 5.8%. 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. 99775 may cover parts of several distinct areas, and a single neighbourhood in Fairbanks 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.
