Alaska Time Zone ZIP Codes

The Alaska time zone (IANA zone identifier America/Anchorage) covers 163 USPS ZIP codes with a combined population of 608,987. Time-zone data on this page is tagged per ZIP rather than per state — several U.S. states sit across zone boundaries (Indiana, Kentucky, Tennessee, Oregon, Idaho, North Dakota, and others), so a ZIP-level tz field is the only way to answer correctly "what time is it in ZIP america-anchorage?" for applications like scheduling, shipping, or call-center routing.

Each ZIP in this view stores its canonical IANA zone string (America/Anchorage in this case), which automatically handles Daylight Saving Time transitions — no static UTC offset needed. Using the IANA identifier rather than a plain UTC offset means downstream tools (databases, cron jobs, APIs) compute the correct wall-clock time without manual DST adjustments twice a year.

The table below lists ZIP codes in Alaska sorted by population. Every ZIP in this time zone is shown below. Each row links to the ZIP's full demographic, housing, and income profile. Time-zone tagging comes from the underlying Census ZIP Code Tabulation Area file cross-referenced with the tz database — the same source used by UNIX, Linux, iOS, and Android for zone data — so the assignments here match what a shipping carrier or phone OS would use for the same five-digit ZIP.
