{"area_code":"605","is_legitimate_code":true,"explanation":"Area code 605 is a legitimate South Dakota area code. The code itself is not a scam, but scammers can spoof any number — including 605 — so individual calls can still be fraudulent.","spoofing_note":"An area code only shows where a number is registered, not who is calling.
