Alaska Address Generator
Alaska is the most caveat-laden member of the NOMAD club. The state itself charges no general sales tax, but Alaska law explicitly allows boroughs and municipalities to impose their own local sales tax — and many do. That makes Alaska a particularly good edge case for checkout testing: the “state sales tax = 0” rule is true, but a full tax engine needs to look up the buyer’s borough to decide whether a local rate applies.
Alaska tax background — the borough-level asterisk
Alaska has no general state sales tax and no personal income tax. The state historically funded itself largely through oil and gas royalties from the Trans-Alaska Pipeline, and Alaskans receive an annual Permanent Fund Dividend distribution from those royalties. To make up for the absence of state tax, boroughs are free to set their own local tax rates, which typically range from 0 % to about 7.5 % and are sometimes seasonal.
A few examples of how varied this can be:
- Anchorage — no local sales tax. The largest city in Alaska is actually a zero-tax destination at the register.
- Juneau — 5 % city sales tax, sometimes seasonal exemptions on essentials.
- Kodiak Island Borough — 7 % sales tax with caps on individual purchase amounts.
- Many small rural communities — rates from 3 % to 7 %, often with unique exemptions for groceries or fuel.
Since 2020, the Alaska Remote Seller Sales Tax Commission has also coordinated marketplace-facilitator collection on remote sellers shipping into participating boroughs, meaning a national retailer might collect Alaska local sales tax based on the buyer’s borough even though the state has none.

Phone numbers are generated with the 907 area code, which has covered the
entire state since the area code was introduced in 1957.
Common use cases
- Local-tax fallthrough test: your state-level rule says “AK = 0”, but a real tax engine returns 5 % for a Juneau ZIP. Use Alaska addresses to verify your code path that combines state and local taxes correctly.
- Marketplace-facilitator compliance test: assert that your platform collects and reports the right local tax when shipping to a participating Alaska borough.
- Shipping zone testing: Alaska is a non-contiguous shipping zone for most carriers — useful to verify the “Non-Continental US” pricing rule in your shipping calculator.
- Time-zone edge case: Alaska Standard Time is UTC-9 / -8, which is unusual enough to surface bugs in scheduling, delivery-window, or appointment-booking UI.
Important caveats
Two layered caveats apply here:
- Address synthesis: street numbers and street names are generated; they will not pass real USPS deliverability or AVS checks. See our AVS & ZIP validation explainer.

“Tax-free” is a half-truth in Alaska: do not assume a
shipping address ending in
AKmeans zero sales tax in your checkout. The state level is zero, but the local level often is not. If your test fixture needs a truly zero-tax US address, prefer Anchorage among the Alaska cities — or pick Delaware or Oregon instead.
