Alaska area codes
Alaska uses 1 area code. Its code 907 has been in service since 1957. It has 657 of its 786 possible number blocks allocated, 83.6% of capacity. Across the state no single national carrier holds the most blocks: 58.0% sits with CLEC and VoIP holders counted together, ahead of GCI at 22.4%. In the 33 days to 30 October 2026, FTC complaints named an Alaska caller ID 194 times – 0.1% of all complaints in the window, most often 907 with 194 (346th of 422 nationally). NANPA records 253 rate centers in 907, and local calls take all ten digits.
The Alaska area code
| Code | In service | Blocks used | Largest holder | Complaints | Shares area with |
|---|---|---|---|---|---|
| 907 | 1957 | 657/786 | Other CLEC / VoIP 58% | 194 | no overlay |
Block share is share of allocated number blocks, not of subscribers. Complaint counts cover 28 Sep – 30 Oct 2026 and reflect spoofed caller IDs as much as real calls.
How full Alaska’s codes are
A code holds at most 786 blocks of 10,000 numbers each. When a code fills up, the administrator does not reclaim numbers – it adds an overlay, and from then on new numbers in the same area come from the new code.

Who holds the number blocks
Counted from every assigned block in the state: 657 blocks, each with the holder NANPA recorded for it. Percentages are measured, not estimated.
| Holder | Blocks | Share of Alaska | Largest in |
|---|---|---|---|
| Other CLEC / VoIP | 381 | 58% | 1 code |
| GCI | 147 | 22.4% | – |
| AT&T | 84 | 12.8% | – |

| Vonage | 1 | 0.2% | – |

| Comcast | 1 | 0.2% | – |
“Other CLEC / VoIP” is not one company: it is every holder outside the national carriers counted together, which is what resellers and app-based numbers look like in the records. This is allocation, not subscribers.
Spam complaints naming Alaska codes
FTC Do Not Call complaints where the caller ID shown was a Alaska number, 28 Sep – 30 Oct 2026 (33 days). Caller IDs on spam calls are routinely faked, so these are complaints about the code, not calls proven to come from it.

Alaska is in Alaska time.
Frequently asked about Alaska area codes
How many area codes does Alaska have?
1 in service. That code is 907.
What is the oldest area code in Alaska?
907, in service since 1957.
What time zone is Alaska in?
Alaska time.
Which Alaska area code gets the most spam complaints?
907 – 194 FTC complaints in the 33 days to 30 October 2026, 346th of 422 codes nationally. Those are complaints about the caller ID shown, and spam callers routinely fake a local-looking number, so this says the code is imitated often, not that the calls come from there.
Which carrier holds the most Alaska numbers?
No one carrier does. 58.0% of the 657 number blocks assigned across Alaska are held by CLEC and VoIP providers outside the national carriers – resellers and app-based numbers look like this in the records. The largest named carrier is GCI with 22.4%. This is allocation of blocks by the numbering administrator, not a count of subscribers – people keep their numbers when they switch carriers.
Do you have to dial 10 digits in Alaska?
Yes. The code is in a ten-digit dialing area, so a local call needs the area code too. Dialing seven digits reaches a recording, not a wrong number.
