Is 626 a scam or spam risk?
626 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 626 number on your screen is no guarantee the caller is in Pasadena, CA or trustworthy.
