What are common questions about ZIP codes in this time zone?

What does a micro Alaska (Sitka) zone page actually cover? ▼
Only 14 ZIP records carry the America/Sitka tag here (combined ACS population 32,638). Treat this as a precise local pocket, not a coast-to-coast zone, open each ZIP profile rather than extrapolating from a thin sample.
Is the Alaska (Sitka) tag essentially a single-state pocket? ▼
Yes for this dataset: every America/Sitka ZIP sits under AK (14 codes · population 32,638). Neighboring civil time may still differ across state lines, the IANA string is the durable key, not the state name.

Yes - America/Sitka observes DST under IANA rules (spring forward / fall back). Store the zone identifier, not a seasonal UTC offset, so transitions stay correct without per-ZIP hand edits.
