Frequently Asked Questions about the 734 Area Code
Who called me from a 734 number?
A 734 number is assigned to Ann Arbor, Michigan, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 734 code to look nearby, so a 734 number doesn't prove the caller is local. Recently, 740 unwanted-call complaints were reported to the FTC for numbers showing the 734 code (56% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 734 a scam area code?
No area code is a scam on its own. 734 is a normal, officially assigned code for Ann Arbor, Michigan. Spam callers spoof local codes to raise the odds you answer, so 734 on your caller ID says nothing about who is really calling. Recently, 740 unwanted-call complaints were reported to the FTC for numbers showing the 734 code (56% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 734 area code?
Repeated calls from different 734 numbers are usually spoofing: a robocaller rotates through 734 numbers so each call looks local and slips past simple blocks. Recently, 740 unwanted-call complaints were reported to the FTC for numbers showing the 734 code (56% 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 734 number?
If you aren't expecting a 734 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 734 area code?
Block a single 734 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 734 code also stops legitimate local calls, so use it only as a last resort.

Yes. 734 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Ann Arbor, Michigan. A real code can still show up on spoofed spam calls, so treat unknown 734 calls with normal caution.
What timezone is the 734 area code in?
