The Telecom Regulatory Authority of India has issued a fresh directive aimed at strengthening consumer trust and reducing financial fraud in voice communications.
As part of this move, insurance sector entities will be required to migrate their service and transactional calls to a designated numbering series within a defined timeline.
TRAI has instructed all entities regulated by the Insurance Regulatory and Development Authority of India to use the 1600-series numbering for service and transactional voice calls. The transition must be completed by February 15, 2026.
The decision follows consultations with IRDAI, and discussions held under the Joint Committee of Regulators. The 1600 series has been earmarked by the Department of Telecommunications to help consumers clearly distinguish genuine service-related calls from other commercial or potentially fraudulent communications.
According to TRAI, around 570 entities have already adopted the 1600-series, with more than 3,000 numbers subscribed so far.
The numbering framework is already applicable to entities regulated by the Reserve Bank of India, the Securities and Exchange Board of India and the Pension Fund Regulatory and Development Authority.
The authority said uniform adoption across regulated financial sectors will improve call traceability, enhance consumer confidence and reduce impersonation-based fraud.
