Reporting unwanted and scam calls from 354 numbers

Canada does not publish per-area-code complaint counts the way the US FCC does. Instead, unwanted and fraudulent 354 calls are handled by these national bodies, and reporting a number helps regulators act on it:

  • Unwanted telemarketing: file a complaint with the National Do Not Call List (DNCL) or call 1-866-580-3625. Registering your own number on the DNCL also reduces legal telemarketing.
  • Scam or fraud calls: report to the Canadian Anti-Fraud Centre (run by the RCMP, OPP and Competition Bureau) at 1-888-495-8501.
  • Spoofed caller ID: Canadian carriers use STIR/SHAKEN caller-ID authentication under CRTC direction, so a spoofed 354 number may show up as unverified on newer phones.
