Spam complaints naming 416
FTC Do Not Call complaints where the caller ID was a 416 number, 28 Sep – 30 Oct 2026 (33 days). Caller IDs on spam calls are frequently spoofed, so these are complaints about the code, not calls proven to originate in it.

NANPA allocates number blocks to rate centers and records their names abbreviated to ten characters, so these are NANPA's codes rather than place names – CHAMPAURBN is Champaign-Urbana, NWYRCYZN01 is a New York City zone. We show them unchanged instead of guessing at the full names.

Frequently asked about 416
Where is area code 416?
Ontario. It covers the same area as 416/437/647.

Not by itself. 416 drew 306 FTC complaints in the 33 days to 30 October 2026, 297th of 422 ranked codes – mid-pack or lower. Spam callers spoof caller IDs, so the only useful check is the full number. The most reported category here is “Reducing your debt (credit cards, mortgage, student loans)”.
