Caller ID: Designed to Display, Not to Verify

The system displaying incoming calls has inherent limitations, allowing scammers to manipulate caller information. RoboCallMeNot provides a clear process for addressing these calls.

(704) 555-0182 ORIGIN: UNKNOWN TELL
Exhibit A

The Foundation of Spoofing

Caller ID was designed decades ago to display a number, not to verify who is actually calling. While STIR/SHAKEN is a newer carrier-level system that attaches a trust attestation to calls, most major U.S. carriers now apply it to the large majority of their traffic. Smaller, non-facilities-based carriers remain a gap scammers exploit to originate spoofed traffic.

95%+ of major carrier traffic now carries a STIR/SHAKEN trust attestation
