{"area_code":"437","is_legitimate_code":true,"explanation":"Area code 437 is a legitimate Ontario area code. The code itself is not a scam, but scammers can spoof any number — including 437 — so individual calls can still be fraudulent.","spoofing_note":"An area code only shows where a number is registered, not who is calling. Caller ID can be spoofed, so the code alone is not proof a call is local, safe, or fraudulent.","ftc_complaints":{"numbers_with_complaints":3,"total_complaints":36,"top_subjects":["Other"],"most_complained":[{"number":"(437) 837-3704","complaints":27,"url":"https://areacode.fyi/number/4378373704"},{"number":"(437) 837-3667","complaints":5,"url":"https://areacode.fyi/number/4378373667"},{"number":"(437) 837-3683","complaints":4,"url":"https://areacode.fyi/number/4378373683"}],"note":"These are FTC Do Not Call complaints filed about specific numbers shown with this area code — frequently spoofed.
