{"area_code":"815","is_legitimate_code":true,"explanation":"Area code 815 is a legitimate Illinois area code. The code itself is not a scam, but scammers can spoof any number — including 815 — 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":124,"total_complaints":506,"top_subjects":["Other","Reducing your debt (credit cards, mortgage, student loans)","Dropped call or no message"],"most_complained":[{"number":"(815) 753-6030","complaints":27,"url":"https://areacode.fyi/number/8157536030"},{"number":"(815) 599-2766","complaints":22,"url":"https://areacode.fyi/number/8155992766"},{"number":"(815) 713-9830","complaints":13,"url":"https://areacode.fyi/number/8157139830"},{"number":"(815) 725-3638","complaints":13,"url":"https://areacode.fyi/number/8157253638"},{"number":"(815) 515-7126","complaints":12,"url":"https://areacode.fyi/number/8155157126"}],"note":"These are FTC Do Not Call complaints filed about specific numbers shown with this area code — frequently spoofed.
