Stir/Shaken is a set of protocols designed to combat the growing problem of caller ID spoofing and fraudulent calls in the telecommunications industry. The protocols work by authenticating the caller's phone number and ensuring that the information displayed on the recipient's caller ID display is accurate and trustworthy. In this blog, we will explore some real-world examples of how Stir/Shaken has prevented caller ID spoofing and fraudulent calls.
Example 1: AT&T's Implementation of Stir/Shaken
In March 2020, AT&T announced that it had completed the implementation of Stir/Shaken across its entire network. According to the company, this implementation resulted in a significant reduction in the number of fraudulent calls received by its customers.
AT&T reported that it was able to block approximately 1.5 billion fraudulent calls in 2019 using a combination of technologies, including Stir/Shaken. Since the implementation of Stir/Shaken, AT&T has reported a 35% reduction in unwanted robocalls.
Example 2: T-Mobile's Use of Caller Verified
T-Mobile has implemented a solution called "Caller Verified," which uses Stir/Shaken technology to authenticate calls and display a "Caller Verified" tag on the recipient's caller ID display. According to T-Mobile, the use of Caller Verified has resulted in a significant reduction in the number of fraudulent calls received by its customers.
T-Mobile reported that since the launch of Caller Verified in 2019, its customers have received approximately 10 billion calls with the "Caller Verified" tag. The company also reported a 48% reduction in scam calls since the launch of Caller Verified.
Example 3: Verizon's Partnership with the FCC
Verizon has partnered with the Federal Communications Commission (FCC) to combat fraudulent calls and robocalls using Stir/Shaken technology. As part of this partnership, Verizon has implemented a system to authenticate calls and display a "Caller Verified" tag on the recipient's caller ID display.
Verizon reported that since the launch of the "Caller Verified" program in 2019, its customers have received approximately 11 billion calls with the "Caller Verified" tag. The company also reported a 30% reduction in unwanted robocalls and a 60% reduction in customer complaints related to unwanted calls.
Example 4: Google's Implementation of Stir/Shaken
In July 2021, Google announced that it had completed the implementation of Stir/Shaken technology across its Google Voice service. According to the company, this implementation resulted in a significant reduction in the number of fraudulent calls received by its customers.
Google reported that since the launch of Stir/Shaken, the company has seen a 50% reduction in scam calls to Google Voice users. Additionally, the company reported a 60% increase in calls answered by users who previously did not answer calls from unknown numbers.
Conclusion
Stir/Shaken technology has proven to be an effective solution to combat caller ID spoofing and fraudulent calls in the telecommunications industry. As demonstrated by the real-world examples provided above, the implementation of Stir/Shaken technology has resulted in significant reductions in fraudulent calls, robocalls, and customer complaints.
As more telecom providers and regulators continue to implement Stir/Shaken technology, it is expected that the problem of caller ID spoofing and fraudulent calls will continue to decline, restoring trust in the phone system and providing customers with a more secure and reliable communication experience.
