Overview
Understanding ZIP code 99640
ZIP code 99640 is assigned to Nondalton, AK, and falls within Lake and Peninsula 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 88 people live inside it.
Household earnings run below the national median. At $51,667, 99640 sits in the lower half, ahead of 18% 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 Nondalton looks like
Housing in 99640 costs below the national median. A typical home is valued at $137,500 against a US median of $207,500. This is firmly renter territory — 79.4% 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 detached single-family houses, which account for 94.1% of housing units here. The median construction year is 1983, making the housing here from the later twentieth century. The vacancy rate of 71.2% is high, which in many places reflects seasonal or second-home use rather than abandonment.
The population skews younger than the country as a whole, with a median age of 35.5 against 42 nationally. The average household holds 2.59 people, and 61.8% are family households.
Getting to work takes 8.2 minutes on average one way. The dominant mode is walked at 50.0% of workers, while 50.0% walk. Commute patterns are one of the better proxies for how a place actually functions day to day.
Where to stay
Where to stay in Nondalton, AK
99640 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, Seattle, WA is about 1594.5 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 99640 is used for
Beyond addressing mail, 99640 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, 99640 offers a compact profile of Nondalton: 88 residents, a median household income of $51,667, 14.5% of adults holding a bachelor's degree or higher, and an unemployment rate of 31.2%. 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. 99640 may cover parts of several distinct areas, and a single neighbourhood in Nondalton 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.
