Is 478 a scam or spam risk?
478 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 478 number on your screen is no guarantee the caller is in Macon, GA or trustworthy.
