Frequently Asked Questions about the 423 Area Code
Who called me from a 423 number?
A 423 number is assigned to Chattanooga, Tennessee, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 423 code to look nearby, so a 423 number doesn't prove the caller is local. Recently, 2,202 unwanted-call complaints were reported to the FTC for numbers showing the 423 code (59% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 423 a scam area code?
No area code is a scam on its own. 423 is a normal, officially assigned code for Chattanooga, Tennessee. Spam callers spoof local codes to raise the odds you answer, so 423 on your caller ID says nothing about who is really calling. Recently, 2,202 unwanted-call complaints were reported to the FTC for numbers showing the 423 code (59% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 423 area code?
Repeated calls from different 423 numbers are usually spoofing: a robocaller rotates through 423 numbers so each call looks local and slips past simple blocks. Recently, 2,202 unwanted-call complaints were reported to the FTC for numbers showing the 423 code (59% 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 423 number?
If you aren't expecting a 423 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 423 area code?
Block a single 423 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 423 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 423?
Area code 423 covers Chattanooga and the surrounding area in Tennessee, spanning 109 cities with about 1,421,060 residents. It shares its area with overlay code 729.
When did area code 423 go into service?
Area code 423 went into service on September 11, 1995. It was split off from area code 615.
Is 423 a real area code?
Yes. 423 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Chattanooga, Tennessee. A real code can still show up on spoofed spam calls, so treat unknown 423 calls with normal caution.
What timezone is the 423 area code in?
The 423 area code is in the Eastern / Central. Because a number can be kept when someone moves or switches to VoIP, a specific 423 caller may not be in that zone.
How do I call a 423 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 423 and the seven-digit number. From a mobile phone you can usually just enter +1 423 followed by the number and let the phone add the exit code for you.
