833 area code is a toll-free number that is not assigned to a geographical area or time zone, but the numbers from that area code can be spoofed by cybercriminals. Therefore, recipients of calls from an 833 area code are urged to take precaution.
They should never disclose their social security number, personal or credit card information to the caller. If the callers claim they are calling from a particular company, hang up, look up the company's number and call the number to verify.
