Frequently Asked Questions about the 623 Area Code

Who called me from a 623 number?

A 623 number is assigned to Phoenix, Arizona, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 623 code to look nearby, so a 623 number doesn't prove the caller is local. Recently, 1,096 unwanted-call complaints were reported to the FTC for numbers showing the 623 code (62% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.

Is 623 a scam area code?

No area code is a scam on its own. 623 is a normal, officially assigned code for Phoenix, Arizona. Spam callers spoof local codes to raise the odds you answer, so 623 on your caller ID says nothing about who is really calling. Recently, 1,096 unwanted-call complaints were reported to the FTC for numbers showing the 623 code (62% flagged as robocalls). Judge the call itself, not the area code.

Why do I keep getting calls from the 623 area code?

Repeated calls from different 623 numbers are usually spoofing: a robocaller rotates through 623 numbers so each call looks local and slips past simple blocks. Recently, 1,096 unwanted-call complaints were reported to the FTC for numbers showing the 623 code (62% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.

Should I answer an unknown 623 number?

If you aren't expecting a 623 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.

How do I block calls from the 623 area code?

Block a single 623 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 623 code also stops legitimate local calls, so use it only as a last resort.

Is 623 a real area code?

Yes. 623 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Phoenix, Arizona. A real code can still show up on spoofed spam calls, so treat unknown 623 calls with normal caution.

What timezone is the 623 area code in?

The 623 area code is in the (UTC-7). Because a number can be kept when someone moves or switches to VoIP, a specific 623 caller may not be in that zone.

How do I call a 623 number from abroad?

From outside the US, dial your country's exit code, then 1 (the US country code), then 623 and the seven-digit number. From a mobile phone you can usually just enter +1 623 followed by the number and let the phone add the exit code for you.
