QUEBEC, Canada Overlay on 418 · complex 273/367/418/581 · planning letter PL-632 Carrier, line type, region and complaint history – built from NANPA number-block records and FTC Do Not Call data, with the source and date on every page.
Every page shows who holds the number blocks, how close the code is to exhaustion, and how often it appears in spam complaints. 437 of the 439 North American geographic codes in the dataset are published; the rest did not pass the quality threshold.
FTC Do Not Call complaints by the area code shown in the caller ID, 28 Sep – 30 Oct 2026 – 282,276 reports across codes. Spam caller IDs are routinely spoofed, so a high count means the code is imitated often, not that the calls come from there.

Codes NANPA has assigned but not yet put into service. Each gets a page as soon as it is assigned, so the answer exists before people start searching for it.
A further 16 codes have relief planning under way, including 509 WA, 580 OK, 626 CA, 828 NC, 949 CA, 956 TX, where the new code has not been picked yet.
The carrier section is not published yet. Insurance deductibles, claim deadlines and support numbers have to be read off each carrier's own current terms, and no page here will quote a figure we have not verified against the source – a wrong deductible is a wrong answer about someone's money.
22 carriers and MVNOs are in the dataset; their pages go live as each one's terms are verified.
169 codes are at or past 95% of capacity and 31 have nothing left at all – but only 3 of them have relief planning open
