Big change for Truecaller
Global caller ID service Truecaller is integrating AI deeper into its systems, which will “interpret” billions of data signals from users around the world to give “contextual insights” on who is calling.
The group, which has a user base of 450 million people, said that its AI-driven approach differs from other systems that use a static database or a tag system.
The new system should provide AI-generated insights on incoming calls, including summaries of user comments about the caller.
This will then flag potential fraud, identify likely spam, or suggest relevant business categories, all in real time.
“This real-time intelligence not only enhances user trust and safety but also reinforces Truecaller’s leadership in the next generation of caller identification technology,” it said.
Notably, while the company also offers a Verified Business badge for official brand identities, the majority of contextual insights shown to users are generated dynamically by AI, requiring no manual labelling or business registration.
With the new AI-driven systems, Truecaller can:
- Indicate whether the caller is a known fraudster or part of a scam network
- Tell if the number is “likely a business” or “likely important”, even if there is not enough community feedback
- Classify the type of business — for example, Delivery, Customer Support, or Insurance
- Alert about suspicious behavior, even before that number has been widely reported by the community
- Provide a single line AI summary of hundreds of user comments, while the phone is still ringing
The group said the system is a response to the growing scale and sophistication of phone scams around the world.
It said that 56 billion spam and fraud calls were identified in 2024, with studies showing worldwide losses from scams topped an estimated $1.03 trillion that year.
“With phone calls and messaging among the most common fraud methods, this highlights the growing urgency of real-time caller intelligence and protection,” it said.
Trouble in South Africa
Even as Truecaller rolls out new AI-led services, the group faces privacy concerns in South Africa.
AI is also a poorly regulated technology in the country, with the implications of these services still to be tested.
Truecaller is already facing scrutiny from South Africa’s Information Regulator, which is currently investigating the app following complaints from both companies and individuals.
According to Norton Rose Fulbright director Rosalind Lake, the regulator has confirmed that the investigation is underway but will not comment until it has concluded.
Truecaller, which many users download to identify who is calling them, has been accused of violating the Protection of Personal Information Act (POPIA).
This is before even factoring in any AI integration, which could further complicate matters.
The system has proven wildly popular in South Africa because it warns users when they may be getting a call from a spammer or scammer who obtained their number unlawfully.
However, it could also be infringing on the rights of legitimate businesses, which must be allowed to contact clients who have agreed to let them do so.
The source of the problem is Truecaller’s crowdsourcing mechanism for flagging spam, which is open to abuse by malicious users or competing businesses.
With AI potentially integrating this in real-time, the impact for businesses could be significant.
The Information Regulator will check Truecaller’s practices against the eight conditions set out in the law.
This includes informing people how their data will be used, ensuring the data is used securely, and not using more personal information than is necessary for the stated purpose.
