The 1600 series was reserved strictly for service and transactional calls — fraud alerts, payment confirmations, account updates. Instead, banks and financial institutions are routing marketing calls through it, pushing credit cards, loans and insurance from numbers that TRAI’s own rules were supposed to keep clean. This is a direct violation of the norms TRAI itself set — yet the regulator’s clarification says nothing about enforcement against these entities, every one of which is registered and squarely within its jurisdiction.
The Ministry of Electronics and IT is reportedly evaluating TRAI’s request to be designated an authorised agency to regulate caller ID and call management apps. The Telecom regulator has approached the ministry seeking powers over apps like Truecaller, and MeitY is consulting the Department of Telecommunications on the legal route. Apps like Truecaller currently fall outside TRAI’s jurisdiction — as intermediaries, they are governed by the IT Act, 2000, which is administered by MeitY.
Meanwhile, caller ID apps like Truecaller remain barred from showing spam tags on these numbers, no matter how many users report them. TRAI’s clarification confirms consumers have no sanctioned way to flag or even block an unwanted 1600-series call — the DND remedy it points to applies only to the 140 series. Truecaller says users now ignore roughly 8 out of 10 calls from these series and block over 5 lakh of them manually every day. Without any information about who is calling, many consumers appear to be avoiding the entire category — which would include genuine bank alerts and service calls.
The clarification restates the rules that apply to caller ID apps, but is silent on enforcement against institutions misusing the series. Until that gap is addressed, the numbers suggest consumers will keep treating these calls the same way — by not answering them.
