{"area_code":"559","is_legitimate_code":true,"explanation":"Area code 559 is a legitimate California area code. The code itself is not a scam, but scammers can spoof any number — including 559 — so individual calls can still be fraudulent.","spoofing_note":"An area code only shows where a number is registered, not who is calling.
