Got a missed call from 623?
Our directory lists 623 for Phoenix, Arizona, but an area code alone cannot establish who is calling. Scammers can fake caller ID to match the first six digits of the number they are dialing, a trick called neighbor spoofing, so a familiar-looking code proves nothing about who is really calling.
If you were not expecting the call, let it go to voicemail. Verify the caller through a trusted contact method before returning the call, and never share personal details with an unverified caller.
Worth knowing: an area code no longer tells you where someone is. Mobile numbers keep their original code when people move, so a 623 number may belong to someone who left Arizona years ago.
Frequently asked questions about 623
Where is area code 623?
Our directory lists area code 623 for Phoenix, Arizona. The listed city is a reference location, not a complete coverage map. A phone number's area code does not establish the caller's current location.
What time zone is area code 623 in?
This directory uses Mountain Time (no DST) (MST) for Arizona. This is state-level guidance; confirm the recipient's local time before calling.
Is area code 623 a scam?
An area code alone cannot tell you whether a call is genuine. Caller ID can be spoofed, including numbers that appear local. Let unexpected calls go to voicemail and verify the caller independently before sharing personal information.
