Why Giving out Your Cell Number Is Dangerous: How to Call Privately Right Now
By James H. Sterling
Internet users often confuse caller ID suppression with call spoofing. The difference is critical, both technically and under federal law.
When you hide your caller ID through *67, you instruct telecom privacy controls to mark your Calling Party Number as confidential. The carrier leaves the caller ID blank and flags the transmission accordingly. This practice is entirely legal under the FCC Truth in Caller ID Act, which protects consumer privacy during legitimate communications.
Call spoofing alters data packets to display a fake, third-party phone number on the recipient's screen. While collection agencies, corporate PBX systems, and doctors calling from home use legal spoofing to show an office headquarters, bad actors abuse it to impersonate banks or law enforcement. Telecom networks now fight malicious spoofing using STIR/SHAKEN cryptographic standards. If you try to run unauthorized spoofing scripts, upstream carriers will flag your calls as "Spam Likely" or drop them from the network altogether.
