New Delhi: The Telecom Regulatory Authority of India (TRAI) has objected to Truecaller’s practice of displaying a “frequently blocked” badge on calls originating from the dedicated 140 and 1600 number series, stating that such labels could mislead users and erode trust in legitimate communications from banks, financial institutions and government agencies.
The regulator believes that the use of such tags may cause consumers to ignore or distrust important calls that are part of India’s regulated telecom communication framework.
TRAI says labels could create unnecessary suspicion
A senior TRAI official said that assigning labels such as “frequently blocked” to regulated number series is not advisable because it may confuse telecom users and create unwarranted suspicion around genuine calls.
Instead of warning labels, TRAI has suggested that users be informed about their ability to block unwanted promotional calls through the regulator’s official Do Not Disturb (DND) preference management system.
According to the regulator, increasing awareness about the DND framework would be a more effective way of empowering consumers while preserving confidence in legitimate communications.
What are 140 and 1600 series numbers?
TRAI has reserved specific number series for different categories of commercial and official communication:
- 1600 Series: Used exclusively for service and transactional calls from regulated entities such as banks, insurance companies, financial institutions and government departments.
- 140 Series: Reserved for promotional and marketing calls made by registered businesses and organisations.
The regulator emphasised that calls from the 1600 series may include critical information such as fraud alerts, transaction verifications, OTP-related assistance, banking notifications and government communications.
Concern over banking and government communications
TRAI warned that consumers should not be discouraged from answering 1600-series calls because these communications often carry important financial and public service information.
The regulator said any label that negatively influences user perception could affect the delivery of essential alerts and notifications.
The issue comes amid an ongoing disagreement between TRAI and Truecaller regarding how calls from dedicated number series should be displayed on caller identification platforms.
Truecaller cites rise in spam concerns
Truecaller has argued that spam-related complaints have increased since the introduction of dedicated number series and restrictions on displaying community-reported spam indicators for such numbers.
According to the company, some users have begun ignoring or blocking calls from these series altogether, which it claims has reduced trust in legitimate business communications.
TRAI, however, maintains that regulated number series were introduced to improve transparency and help consumers distinguish between promotional, service and government communications while allowing them to manage preferences through official channels.
The regulator has reiterated that preserving trust in critical banking and government calls remains a priority as India continues to strengthen its telecom consumer protection framework.
