You're looking at a map of Alaska and realize it's huge. Like, really huge. Most people think an anchorage alaska postal code is just a simple five-digit string, but if you’re trying to mail a heavy parka to a friend or coordinate a logistics shipment for a North Slope project, that one number is just the tip of the iceberg. Anchorage isn't just a city; it’s a massive sprawling basin.
The 995 prefix rules here.
Basically, if you see a zip code starting with 995, you’re looking at the Anchorage area. But here is the kicker: Anchorage has over a dozen different codes. Each one tells a story about where you are—whether you’re in the high-density downtown blocks or tucked away in the Chugach foothills where bears literally wander through your backyard.
Why the Anchorage Alaska Postal Code Matters More Than You Think
Shipping to Alaska is a nightmare. Honestly, it’s expensive. Most Lower 48 retailers treat Alaska like it’s a foreign country, and that’s where the specific anchorage alaska postal code becomes a financial tool.
Take 99501. That’s the heart of downtown. It’s where the administrative buildings sit and where the tourists wander around the Log Cabin Visitor Information Center. If you’re shipping there, it’s "easy" by Alaska standards. But move further out to 99507 or 99516, and you’re dealing with different terrain, different delivery speeds, and sometimes different surcharges.

People often confuse Anchorage’s urban sprawl with a standard midwestern city. It isn't. The city covers nearly 2,000 square miles. That is larger than the state of Rhode Island.
When you type in an anchorage alaska postal code, you are navigating a landscape that includes a massive military base (JBER), a major international cargo hub (Ted Stevens International), and residential zones that feel like wilderness.
Breaking Down the Main Codes
Most of the action happens in a few key spots.
99501 is the urban core. You’ve got the Anchorage Museum and the coastal trail. It’s dense.
Then you have 99502, which hugs the airport area. This is the lifeblood of the state. Because of the great circle route, Anchorage is a few hours from both Tokyo and New York. If you’re a logistics nerd, 99502 is essentially the center of the world's air cargo. FedEx and UPS have massive footprints here.
99503 and 99504 cover the Midtown and East side. These are the "working" parts of the city. You’ve got the malls, the car dealerships, and a lot of the residential housing for the people who actually keep the city running.
Then there’s 99516.
This is the "Hillside." It’s where the houses get bigger and the views of Cook Inlet get more dramatic. It’s also where you’re most likely to have a moose eat your mailbox. Delivering mail here in January is a feat of strength. The postal workers deserve a medal for navigating those steep, icy driveways.
The Logistics of the 99506 and 99505 Military Zones
Joint Base Elmendorf-Richardson, or JBER, is a world of its own. It has its own postal codes: 99506 and 99505.
If you are sending mail here, you aren't just sending it to Anchorage. You are sending it to a federal installation. There are rules. Sometimes mail gets routed through different channels. If you’re a military family moving up, getting your anchorage alaska postal code sorted is the first step in a very long transition process.
Why Shipping Companies Hate (and Love) 995
Ever tried to use "free shipping" on a website only to see the dreaded Does not ship to Alaska/Hawaii? It happens because of the way zip codes are tiered.
Anchorage is lucky. Because it’s the main hub, it’s "Zone 8" for most carriers. It’s the cheapest part of Alaska to ship to. If you lived in a rural "bush" village with a zip like 99654 or something even more remote, you might pay double.
Even within the anchorage alaska postal code system, there are nuances.
Business owners in 99501 often get better rates or faster pickup times than someone out in the 99516 foothills. It’s all about the density of the route.
The Weird History of 99513 and Remote Anchorage
Did you know Anchorage technically "owns" land that isn't connected to the main road system?
There are areas under the Municipality of Anchorage jurisdiction that feel like the middle of nowhere. While the primary codes stay in the 99501-99524 range, the way the USPS handles "Anchorage" can sometimes include regional sorting hubs.
Wait.
Let’s talk about the P.O. Boxes. Anchorage has a massive reliance on P.O. Boxes compared to other cities. 99510, 99520, 99521—these are largely for box holders. In a state where people move around for seasonal work (fishing, oil, tourism), having a permanent P.O. Box in a central anchorage alaska postal code is a survival tactic.
Common Mistakes When Using an Anchorage Alaska Postal Code
- Ignoring the +4 extension. In a city where three different streets might have similar names (Alaskan logic is... unique), that four-digit extension saves your package from ending up at a trailhead instead of your door.
- Confusing Eagle River. People often think Eagle River is a separate city. It’s technically part of the Municipality of Anchorage, but it uses 99577. If you use an Anchorage city name with 99577, the mail usually gets there, but it’s slower.
- Assuming "Overnight" means overnight. Even with a 99501 code, "overnight" from the Lower 48 usually means two days. The planes have to fly over Canada, after all.
The Impact of 995 on Real Estate and Business
If you’re looking at property, the zip code is a status symbol or a utility marker.
99516 is where the money is. 99501 is where the "vibe" is. 99504 is where the value is.
Real estate agents use the anchorage alaska postal code to filter for school districts. For example, the 99515 area (South Anchorage) is highly coveted for its proximity to newer schools and shopping centers like the Dimond Center.
Business owners also look at these codes for tax purposes. While Alaska has no state sales tax, the municipality has its own rules. Knowing exactly which code your business sits in determines your logistics costs and your accessibility to the workforce.
Actionable Steps for Navigating Anchorage Mail
If you are moving to the area or shipping something critical, don't just guess.
First, use the USPS Look Up tool to verify if a property is in Anchorage proper or Eagle River/Chugiak. They are all under the Anchorage "umbrella" but have vastly different delivery timelines.
Second, if you’re shipping to a 995 code, always check if the carrier (UPS/FedEx) considers it "Remote" or "Urban." Even within Anchorage, some areas are flagged as high-cost delivery zones.
Third, if you’re a business, try to get a 99501 or 99503 address. These are the most central for courier services and usually get the first deliveries of the day.
The anchorage alaska postal code you choose is more than just a number; it’s your coordinates in the Last Frontier. It dictates how much you pay for your Amazon packages, how fast you get your heater parts in the middle of a sub-zero January, and whether or not the delivery driver is going to have to dodge a grizzly bear to get to your porch.
To ensure your mail actually reaches its destination in the land of the midnight sun, always double-check the specific street suffix—whether it’s "Street," "Court," or "Circle"—because in Anchorage, those distinctions are the difference between a successful delivery and a package lost in the snow.
