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 Hawaii’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.

“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 Hawaii codes

FTC Do Not Call complaints where the caller ID shown was a Hawaii 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.

Hawaiian Telcom, with 45.4% of the 694 blocks assigned across Hawaii, ahead of Verizon at 11.1%. 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 Hawaii?

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.
