India Mandates Caller-ID Apps Share Spam Reports with Telcos
India's telecom regulator, TRAI, has amended rules to require caller-ID and call-management apps, such as Truecaller, to share user spam reports with telecom operators via a blockchain-based platform. The move aims to broaden the spam report pool for enforcement. Truecaller, which has over 500 million monthly active users globally and 350 million in India, called the requirement anti-competitive, citing a one-way exchange of valuable data. The amendments also bring AI-powered and automated calls under the A2P framework, requiring declaration to operators or being treated as spam. Telecom operators may levy termination charges up to 5 paise per minute. The rules raise questions about data sharing scope, enforcement, and consent. India reported around 42 billion spam calls in 2025, with Truecaller blocking 12 billion.
Major regulatory change in India's telecom sector impacting caller-ID apps and AI-powered calls, with implications for adtech and communication platforms, given India's market scale.

Truecaller clashes with TRAI over anti-spam rules
Truecaller publicly challenged India’s telecom regulator (TRAI), saying a 2024 framework that designates 1400 and 1600 number series for commercial communications prevents caller ID apps from displaying community-reported spam labels and has reduced trust in those business numbers. CEO Rishit Jhunjhunwala posted that Truecaller users ignored 81% of calls from the 1400 series and 79% from the 1600 series over eight months, and manually blocked 74 million calls from those series. The dispute follows reporting that TRAI has sought powers under the Information Technology Act to act against caller ID apps that label calls from the designated series as spam. Truecaller said it will share data with India’s IT ministry and urged evidence-based regulation.
Truecaller Reaches 500 Million Monthly Users
Sweden-based caller ID app Truecaller announced it reached 500 million monthly active users, including more than 350 million monthly users in India and about 150 million users outside India. The company added 50 million users in 2025 and says its user base has doubled over the past five years; in April 2025 it reported over 450 million users. Truecaller also reports more than 4 million paid subscribers. The company is expanding beyond caller ID with features such as family-group call admin controls and AI experiments to screen, answer and monitor calls for scam-related keywords. Truecaller said it faces challenges from India’s Caller Name Presentation (CNAP) system. CEO Rishit Jhunjhunwala framed the milestone as evidence of demand for protection from spam and scams and said the company is targeting 1 billion users next.
Truecaller launches Scam Checker for the open web
Truecaller, the Swedish caller ID app with over 500 million monthly users, has launched Scam Checker, a free web and Android service that lets users check suspicious phone numbers, links, or messages for fraud without needing an account or app installation. For numbers, it cross-references a database of known spam; for links, it expands shortened URLs and checks against a risk database; for messages, it compares content against community-reported scams. Initially available in India, the tool will expand to Latin America, the Middle East, Africa, and Southeast Asia. Scam Checker leverages Truecaller's community-powered ScamFeed and broadens the company's focus into general scam detection. This move comes amid competitive pressure in India and alarming global scam statistics. Truecaller plans to add support for more scam types and allow screenshot uploads.
