{"area_code":"423","is_legitimate_code":true,"explanation":"Area code 423 is a legitimate Tennessee area code. The code itself is not a scam, but scammers can spoof any number — including 423 — 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":75,"total_complaints":360,"top_subjects":["Other","Calls pretending to be government, businesses, or family and friends","Dropped call or no message"],"most_complained":[{"number":"(423) 822-2465","complaints":25,"url":"https://areacode.fyi/number/4238222465"},{"number":"(423) 552-1410","complaints":22,"url":"https://areacode.fyi/number/4235521410"},{"number":"(423) 509-3988","complaints":17,"url":"https://areacode.fyi/number/4235093988"},{"number":"(423) 960-1949","complaints":13,"url":"https://areacode.fyi/number/4239601949"},{"number":"(423) 354-0175","complaints":11,"url":"https://areacode.fyi/number/4233540175"}],"note":"These are FTC Do Not Call complaints filed about specific numbers shown with this area code — frequently spoofed.
