Frequently Asked Questions about the 906 Area Code
Who called me from a 906 number?
A 906 number is assigned to Marquette, Michigan, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 906 code to look nearby, so a 906 number doesn't prove the caller is local. Recently, 83 unwanted-call complaints were reported to the FTC for numbers showing the 906 code (70% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 906 a scam area code?
No area code is a scam on its own. 906 is a normal, officially assigned code for Marquette, Michigan. Spam callers spoof local codes to raise the odds you answer, so 906 on your caller ID says nothing about who is really calling. Recently, 83 unwanted-call complaints were reported to the FTC for numbers showing the 906 code (70% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 906 area code?
Repeated calls from different 906 numbers are usually spoofing: a robocaller rotates through 906 numbers so each call looks local and slips past simple blocks. Recently, 83 unwanted-call complaints were reported to the FTC for numbers showing the 906 code (70% 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 906 number?
If you aren't expecting a 906 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 906 area code?
Block a single 906 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 906 code also stops legitimate local calls, so use it only as a last resort.
