What Does “Calls with Checkmark Have Been Verified by the Carrier” Mean (Verizon)?

Have you ever noticed a checkmark next to a phone number on your caller ID with Verizon? This mark signifies that the call has undergone a verification process through a technology known as STIR/SHAKEN.

Understanding STIR/SHAKEN

STIR/SHAKEN stands for Secure Telephone Identity Revisited (STIR) and Signature-based Handling of Asserted information using Tokens (SHAKEN). It’s a framework designed to combat caller ID spoofing, a deceptive tactic where scammers manipulate their caller ID to appear as a legitimate source, such as your bank or a local number.

How Does Call Verification Work?

STIR/SHAKEN operates by relying on certificates issued by phone carriers. When a call is placed, the originating carrier verifies the customer’s identity and confirms their authorization to use the displayed caller ID. This information is then passed on to the receiving carrier, who can determine the call’s legitimacy and display a checkmark for verified calls on the recipient’s phone.

What Does a Checkmark Mean for You?

A checkmark signifies a higher level of trust in the caller’s identity. While not foolproof, it offers a significant advantage compared to unverified calls. You’re more likely to be receiving a call from the number displayed on your screen, reducing the risk of falling victim to spoofing scams.

Current Knowledge and Limitations

It’s important to acknowledge that STIR/SHAKEN is still under development. While it represents a significant step forward, limitations exist:

• Carrier Participation: Not all carriers participate fully in STIR/SHAKEN, so verification might not be available for all calls.
• Spoofing Techniques: Sophisticated scammers may find ways to circumvent the system.

Solutions and Additional Information

Here are some additional points to consider:

Carrier Support: Check if your carrier actively supports STIR/SHAKEN.

Phone Compatibility: Ensure your phone software is updated to display call verification information.

Continued Vigilance: Even with a checkmark, stay cautious. Don’t share personal information over the phone unless you’re absolutely certain of the caller’s identity.

Conclusion

STIR/SHAKEN technology offers a valuable tool in the fight against caller ID spoofing. While limitations exist, verified calls (indicated by a checkmark) provide a greater degree of trust in the caller’s identity. Remember, vigilance remains important. Don’t hesitate to end a call if you suspect a scam.
