The Telecom Regulatory Authority of India has expanded its anti-fraud measures by creating a dedicated 1601 numbering range for utility, courier, and logistics calls, simplifying caller identification and reducing impersonation scams.
India’s telecoms regulator has broadened its anti-fraud push by creating a new 1601 numbering range for service and transactional calls from utilities, courier firms and logistics operators, extending a system that already separates genuine banking and government communications from ordinary mobile traffic. The Telecom Regulatory Authority of India said the move is designed to give consumers an easier way to identify legitimate calls and reduce impersonation scams that rely on familiar-sounding service messages.
The new block sits alongside the existing 1600 series, which has been reserved for the banking, financial services, insurance and government sectors. Industry explainers on the numbering plan say the wider framework is meant to let recipients recognise the origin of a call at a glance, making it harder for fraudsters to pose as trusted institutions. The latest expansion marks a further step in that approach by giving non-financial essential services their own clearly defined channel.
According to the directive, the rollout will happen in phases, with the first stage limited to consumer essential services. That means electricity distributors, municipal water suppliers, city gas networks and LPG suppliers will be among the first to receive the new numbers, along with express parcel delivery companies, courier operators and freight firms handling consignments. TRAI has also said the Department of Telecommunications will allocate the numbers, while telecom operators must complete verification before the lines are issued directly to eligible businesses, without intermediaries or aggregators in the chain.
Businesses using the 1601 series will have to sign an undertaking that the numbers will be used only for service and transactional communication. Promotional calling will not be allowed on the new range. Telecom operators have been given 90 days from the date of the directive to complete onboarding and migration for eligible entities in the first phase, a timetable that suggests the regulator wants the system in place quickly rather than as a long-term consultation.
The move also fits into a broader regulatory clampdown on call spoofing and spam. The Economic Times and The Times of India reported that TRAI has separately barred apps from blocking, tagging or filtering calls from the 1600 series, because those calls are meant to carry important service updates from authorised institutions. Promotional calls on the 140 series, by contrast, remain subject to users’ do-not-disturb preferences. Taken together, the measures show TRAI trying to preserve access to legitimate notices while making suspicious or commercial calls easier to spot.
