708 overlay codes and dialing
The 708 territory is covered by an overlay of 2 area codes: 464, 708. All of them serve the same geographic area, and the original code is 708. 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.
History of the 708 area code
708 went into service on November 11, 1989, created when it was split from 312. It serves Cicero and the surrounding part of Illinois, and today shares its territory with overlay code 464. For how codes are created, split, and overlaid, see how area codes work.
Is 708 a scam or spam risk?
708 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 708 number on your screen is no guarantee the caller is in Cicero, IL or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
