India Orders Caller-ID Apps to Share Spam Reports
India’s telecom regulator now requires caller-ID and call-management apps to send user spam reports to telecom operators. The rules also classify undeclared automated and AI-generated calls as spam and allow operators to charge for some app

India’s Telecom Regulatory Authority has expanded its anti-spam rules to require caller-ID and call-management apps to send user spam reports to telecom operators, creating a direct link between private reporting databases and the telecom sector’s enforcement system.
The amendment, announced on Friday, September 18, requires apps that let users flag calls as spam or junk to transmit those reports to a blockchain-based platform maintained by telecom operators. TRAI says the change will give operators more information to identify and act against senders of unwanted commercial communications.
Truecaller, India’s largest caller-identification app by reach, has objected to the requirement. The company told TechCrunch that the arrangement creates a “one-way exchange” in which telecom operators receive commercially valuable data collected by call-management apps without providing equivalent information in return.
TRAI Connects App Reports to Its Telecom System
The new rule joins two systems that have operated largely apart. Telecom operators run the network and the distributed-ledger platform used to register commercial communications, while apps such as Truecaller use user reports, automated detection and other signals to identify suspicious numbers.
Sumeysh Srivastava, a partner at New Delhi-based consulting firm The Quantum Hub who leads its telecom-regulation policy work, told TechCrunch that the change creates technical and jurisdictional questions. Apps that are not telecom operators will need to follow reporting standards, but the amendment does not fully explain how compliance will be enforced against them.
The scope of the information-sharing requirement also remains unclear. Kazim Rizvi, founding director of New Delhi-based policy think tank The Dialogue, said there is a significant difference between forwarding a specific report made by a user and handing over the broader datasets, reputation signals or analytical systems an app uses to identify suspicious calls.
TRAI did not respond to TechCrunch’s questions about what information apps must transmit, how users will be notified or asked for consent, or whether the rule covers spam-reporting tools built into Android and iOS dialers.
Truecaller Calls the Arrangement Anti-Competitive
India is Truecaller’s largest market, with well over 350 million of the company’s more than 500 million monthly active users. The Stockholm-based company relies partly on community reports to identify and block unwanted calls, making the new reporting obligation directly relevant to a major source of its product data.
“While our data and user sentiment clearly show that spam has skyrocketed due to this free pass to spammers, we have been compliant with this since late last year,”
Truecaller spokesperson, quoted by TechCrunch
The amendment keeps an existing restriction that prevents call-management apps from blanket blocking, filtering or labeling calls from certain government-designated number ranges used for promotional, service and transactional communications. Users can still block individual calls on their own devices.
Truecaller has previously objected to those restrictions, arguing that exempting designated number ranges from automated spam labels can allow unwanted calls to escape its filters. The company’s dispute with TRAI therefore covers both the information it must provide to operators and the calls its own software can flag.
India’s Spam Numbers Are Measured in Billions
The policy arrives after years of enforcement aimed at unsolicited commercial communications. TRAI said in a February 2026 update that users submitted 3.109 million UCC complaints through all channels during 2025, including 1.706 million through its Do Not Disturb application.
The same update said TRAI issued 731,120 notices to unregistered telemarketers in 2025. Authorities imposed one-month communication restrictions on 473,075 entities, extended restrictions of up to six months to 89,936 repeat offenders and disconnected 184,482 telecom resources during the year.
Truecaller reported a larger measure of the problem in its own February report, saying users in India encountered about 42 billion spam calls in 2025, counting calls that were blocked, labeled or ignored. The company said it blocked nearly 12 billion of those calls.
Rizvi said the final rules need clearer requirements for the information apps must provide, the way consumers are informed and how the data can be retained or used. Without those details, the regulation leaves open questions about privacy, consent and the commercial value of crowd-sourced spam intelligence.
AI Voice Agents Enter the A2P Rulebook
The amendment also changes how India treats automated calling. Calls made without a person directly dialing the number now fall under TRAI’s application-to-person, or A2P, framework. The category includes robocalls and calls using prerecorded or artificial voices.
Businesses using automated calling systems must declare that use, along with the phone numbers involved, to their telecom operators in advance. TRAI says an undeclared A2P call will be treated as spam.
The rules focus on how a call begins rather than only on whether the voice was generated by software. Srivastava told TechCrunch that approach leaves uncertainty around calls in which a person initiates the interaction but software handles part of the conversation.
Satya N. Gupta, a former additional secretary at TRAI, said the amendment does not prohibit businesses from using AI or other automated calling tools. It requires them to disclose those systems to telecom operators.
Operators may also charge a termination fee of up to 5 paise per minute for A2P calls, although certain designated number ranges are exempt. Rizvi warned that the definition could extend to software-assisted contact-center calls and click-to-call services where a person remains involved.
“Without that distinction, the A2P category risks becoming broader than the regulatory harm it is intended to address,”
Kazim Rizvi, founding director, The Dialogue
India’s new rules therefore place caller-ID apps, telecom operators and automated calling companies inside the same reporting structure. The immediate dispute is over who controls the data that identifies spam, while the operational questions concern what apps must send, what users must approve and how automated calls will be classified.
