{"area_code":"503","is_legitimate_code":true,"explanation":"Area code 503 is a legitimate Oregon area code. The code itself is not a scam, but scammers can spoof any number — including 503 — 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":67,"total_complaints":317,"top_subjects":["Other","Dropped call or no message","Calls pretending to be government, businesses, or family and friends"],"most_complained":[{"number":"(503) 436-7151","complaints":26,"url":"https://areacode.fyi/number/5034367151"},{"number":"(503) 436-7160","complaints":23,"url":"https://areacode.fyi/number/5034367160"},{"number":"(503) 465-8600","complaints":18,"url":"https://areacode.fyi/number/5034658600"},{"number":"(503) 436-7197","complaints":13,"url":"https://areacode.fyi/number/5034367197"},{"number":"(503) 987-3673","complaints":9,"url":"https://areacode.fyi/number/5039873673"}],"note":"These are FTC Do Not Call complaints filed about specific numbers shown with this area code — frequently spoofed.
