The 331 area code is often used for fake legal complaint calls and government impersonation scams. Fraudsters pretend to be officials to scare you into handing over money or personal identification.
"Claim to have a complaint on file and if I do not address the compliant they will contact my HR payroll at work. Go find a job and stop scamming people that work hard for their money."
"Officer Andrew Hall said I have an arrest warrant out for me because of suspicious activity on my SS card... need I say more? SCAMMER"
"They left a voicemail stating to authorize the payment of $999 for the recent order of Apple iPhone 16 Pro on your account. If you do not authorize this payment, please press 1 to speak to our customer support representative."
"These low-lifes call up hoping to sell you auto protection (after your warranty has run out). I don't have an automobile and I have had so many of their calls that I'm nauseous. Tried being dropped from their call list, and the rep hung up on me."
"no company name as to who is calling and leaving a prerecorded message that will only take a few moment of my time and that anything related to my health coverage no matter the answer will not be affected."
"I just got 7 calls in row."
Area code 331 covers a significant portion of the western suburbs of Chicago, Illinois. This includes areas within DuPage, Cook, Kane, and Will counties, as well as a small portion of Kendall County.
Area code 331 is an overlay to area code 630 . Area code 630 was created in 1996. Area code 331 was introduced on October 7, 2007, overlaying area code 630. Ten-digit dialing is mandatory in this area.
No, 331 is a legitimate area code serving the western Chicago suburbs, including Aurora and Naperville. Scammers spoof it to capitalize on its association with affluent Chicago-area communities.
Fake judicial-services calls threatening HR departments and payroll offices to embarrass victims at work are heavily reported. Government agency impersonation claiming arrest warrants under fake badge numbers, and aggressive auto-protection robocalls, are also highly active.
