What this ZIP is

99821 has no measured residential population

This is not missing data. USPS assigns some ZIP codes exclusively to PO Box clusters, or to a single high-volume recipient such as a government office, university mailroom, or large business. Nobody is counted as living there. The US Census Bureau only publishes demographic estimates for ZIP Code Tabulation Areas (ZCTAs), which are built from residential census blocks. 99821 has no matching ZCTA, so there is genuinely nothing to report for population, income, or housing — rather than a figure of zero.

Overview

Understanding ZIP code 99821

ZIP code 99821 is assigned to Auke Bay, AK, and falls within Juneau City and Borough. 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. This particular code, however, has no residential population attached to it — more on that below.

Where to stay

Where to stay in Auke Bay, AK

Practical uses

What ZIP code 99821 is used for

Beyond addressing mail, 99821 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.

Because 99821 carries no residential population, it is used almost entirely for delivery and administrative routing rather than for demographic analysis. If you are researching the area around it, the neighbouring postal codes listed further down this page will be far more informative.

One caution worth repeating: a postal code is not a neighbourhood. 99821 may cover parts of several distinct areas, and a single neighbourhood in Auke Bay 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.

Questions

Common questions about 99821

What city is ZIP code 99821 in?
99821 serves Auke Bay, Alaska, in Juneau City and Borough, United States.
Why is there no population data for 99821?
99821 is a non-residential ZIP code — either a PO Box cluster or a code assigned to a single high-volume recipient. The Census Bureau only publishes demographic data for ZIP Code Tabulation Areas, which are built from residential census blocks. 99821 has no matching ZCTA, so no population figure exists.
What time zone is 99821 in?
99821 observes Alaska Time (America/Juneau). This zone observes daylight saving time.
Does 99821 cover more than one city or county?
This page lists Auke Bay as the primary place and Juneau City and Borough 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 99821 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.

Methodology

Where this data comes from

  • Postal geography — GeoNames open postal code database (CC BY 4.0), cross-checked against the US Census Gazetteer.
  • Weather — NOAA National Weather Service, fetched live in your browser.
  • Map — OpenStreetMap contributors (ODbL).
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.
