Dialing 414
Milwaukee, WI is currently served by the single area code 414, with no overlay. Ten-digit dialing (area code + seven-digit number) always works and is increasingly the norm nationwide; some local calls may still connect with seven digits. If a future overlay is added, 10-digit dialing would become mandatory.
From outside the US, dial +1 414 followed by the seven-digit number.
History of the 414 area code

Is 414 a scam or spam risk?
414 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 414 number on your screen is no guarantee the caller is in Milwaukee, WI or trustworthy.
