619 overlay codes and dialing
The 619 territory is covered by an overlay of 2 area codes: 619, 858. All of them serve the same geographic area, and the original code is 619. Because more than one code covers the same ground, 10-digit dialing is mandatory — you must dial the area code for every local call. New phone lines may be assigned any of these codes.

619 went into service on January 1, 1982, created when it was split from 714. It serves San Diego and the surrounding part of California, and today shares its territory with overlay code 858. For how codes are created, split, and overlaid, see how area codes work.
Is 619 a scam or spam risk?
619 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 619 number on your screen is no guarantee the caller is in San Diego, CA or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
