Overview

Understanding ZIP code 99658

ZIP code 99658 is assigned to Saint Marys, AK, and falls within Kusilvak 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 1,009 people live inside it.

At 24 residents per square mile spread over 42.88 square miles, 99658 reads as a rural 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 are well below the national median. At $46,667, 99658 ranks among the lower-income postal codes, ahead of 12% 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 Marys looks like

Housing in 99658 costs below the national median. A typical home is valued at $109,600 against a US median of $207,500, and median gross rent runs $1,150 a month. The split between owning and renting is fairly even at 67.0% 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 87.7% of housing units here. The median construction year is 1987, making the housing here from the later twentieth century.

The population skews notably young, with a median age of 25.6 against 42 nationally. Households are relatively large at 3.43 people on average, with 78.9% classified as family households.

Getting to work takes 6.9 minutes on average one way. The dominant mode is walked at 28.4% of workers, while 28.4% 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 Saint Marys, AK

99658 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.

Median rent in 99658 is $1,150 a month, which sits in the middle of the national range; accommodation pricing locally tends to be similarly mid-market. For reference, Seattle, WA is about 1864.7 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 99658 is used for

Beyond addressing mail, 99658 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, 99658 offers a compact profile of Saint Marys: 1,009 residents, a median household income of $46,667, 7.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 23.1%. 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. 99658 may cover parts of several distinct areas, and a single neighbourhood in Saint Marys 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.

Does 99658 cover more than one city or county?
This page lists Saint Marys as the primary place and Kusilvak County as the county. ZIP codes follow mail delivery routes rather than municipal or county lines, so a single code can straddle boundaries, and USPS also recognises alternate acceptable city names for many codes. If you need the definitive answer for a specific street address, the USPS ZIP Code Lookup is the authority.
Can ZIP code 99658 change?
Yes. USPS adjusts ZIP codes as delivery volumes shift — codes are occasionally split, merged, retired or newly created, and boundaries move more often than most people assume. The Census Bureau's ZCTA definitions, which underpin the demographic figures on this page, are redrawn only once a decade, so the two can drift apart between censuses.

On accuracy. ACS figures are survey estimates, not counts. The margin of error shown alongside the population figure means the true value has a 90% chance of falling in that range. For small ZIP codes the error can be large relative to the estimate — treat the direction as more reliable than the exact number.
