Stop Displaying Spam Labels On Calls Originating From 140 & 1600 Number Series: TRAI Directs Truecaller

TRAI has directed caller identification apps like Truecaller to stop showing spam labels on calls from 140 and 1600 series numbers. The regulator said these are official business lines used for telemarketing and banking services. The move aims to prevent genuine calls from being blocked due to user-generated spam reports.

The Telecom Regulatory Authority of India (TRAI) has directed caller identification apps including Truecaller to stop displaying spam labels on calls originating from the 140 and 1600 number series. The 140 series is used for telemarketing calls, while the 1600 series is reserved for banking and financial service communication such as payment alerts and account updates.

TRAI says numbers are official business lines

TRAI has maintained that these number series are official business lines and that genuine calls were being blocked because of user reports flagging them as spam. The regulator's 2025 amendments to the Telecom Commercial Communications Customer Preference Regulations stated that third party call management apps should not block or tag calls from these designated series. TRAI's concern is that if users report many 140 series numbers as spam, apps relying on crowd sourced data may end up blocking an entire category of calls, which could also affect registered businesses and government linked communication.
