330 overlay codes and dialing
The 330 territory is covered by an overlay of 2 area codes: 234, 330. All of them serve the same geographic area, and the original code is 330. 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 330 area code
330 went into service on March 9, 1996, created when it was split from 216. It serves Akron and the surrounding part of Ohio, and today shares its territory with overlay code 234. For how codes are created, split, and overlaid, see how area codes work.
Is 330 a scam or spam risk?
330 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 330 number on your screen is no guarantee the caller is in Akron, OH or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
