Truecaller Pushes Back Against India’s Telecom Anti-Spam Regulations

Truecaller has publicly challenged India’s telecom regulator over rules governing caller ID applications, arguing that the country’s anti-spam framework is making it more difficult to protect users from unwanted and fraudulent calls in its largest market.

On Wednesday, Truecaller CEO Rishit Jhunjhunwala took to X to criticise the Telecom Regulatory Authority of India (TRAI), claiming that the regulator prevents the company from displaying community-reported spam information for calls originating from India’s dedicated 1400 and 1600 number series. According to Jhunjhunwala, the restriction has allowed the misuse of these numbers while reducing public trust in legitimate business communications.

The disagreement centres on a regulatory framework introduced in 2024, under which TRAI assigned the 1400 and 1600 number ranges exclusively for commercial communications. Businesses use 1400-series numbers for telemarketing calls, while 1600-series numbers are reserved for service-related and transactional communications. The regulator later required businesses to migrate to these dedicated number ranges, saying the move would help consumers distinguish genuine business calls from spam and scam attempts.

The policy was introduced as India continued to tackle the growing problem of spam and fraudulent calls across one of the world’s largest telecom markets. Regulators and telecom operators have implemented multiple initiatives to curb misuse. Last year, India’s communications ministry reported that authorities had disconnected more than 2.1 million fraudulent mobile numbers and taken enforcement action against over 100,000 entities.

Jhunjhunwala argued that the framework has produced unintended results. Citing internal Truecaller data, he said users have increasingly lost confidence in calls originating from the designated number series. According to the company, Truecaller users ignored 81% of calls from 1400-series numbers and 79% from 1600-series numbers during the past eight months. Over the same period, users manually blocked 74 million calls from those two number ranges, while daily blocking of 1600-series numbers has more than tripled since October 2025.

Because Truecaller cannot label those numbers as spam under the existing rules, the company introduced a “Frequently Blocked” badge that alerts users whenever many users have blocked a number in the designated series.

The public dispute intensified after The Economic Times reported that TRAI had sought powers under India’s Information Technology Act to take action against caller ID applications, including Truecaller, Hiya, and Whoscall, for marking numbers from the 1400 and 1600 series as spam.

Neither TRAI nor India’s Ministry of Electronics and Information Technology, which would review any such proposal, immediately responded to requests for comment.

The disagreement comes at an important time for Truecaller, as its core caller-identification business faces increasing regulatory scrutiny and intensifying competition. At the same time, the company continues to expand into additional products and services. India remains by far Truecaller’s largest market, accounting for more than 350 million of its approximately 500 million monthly active users.

Jhunjhunwala said the company plans to submit its data to India’s IT ministry as part of the regulatory review process, arguing that decisions affecting caller ID platforms should be based on evidence and real-world user data.

In his public statement, he urged regulators to focus enforcement efforts on those responsible for fraudulent activity rather than companies like Truecaller, which he said play an important role in helping consumers identify unwanted and suspicious calls.
