Description
TRAI issues direction mandating phase-wise adoption of 1600-series numbering by entities regulated by RBI, SEBI, and PFRDA to enhance consumer trust and prevent fraudulent voice calls.
Summary
The Telecom Regulatory Authority of India (TRAI) has issued a mandatory direction on November 19, 2025, requiring phase-wise adoption of the ‘1600’ numbering series by entities regulated by RBI, SEBI, and PFRDA. This initiative aims to enhance consumer trust, curb spam, and prevent fraudulent activities through voice calls. The 1600-series will enable citizens to reliably identify legitimate calls from regulated financial institutions. Approximately 485 entities have already adopted the series with over 2,800 numbers subscribed.
Key Points
- TRAI mandates time-bound adoption of 1600-series numbers for BFSI sector entities
- The 1600-series is specifically assigned to distinguish service and transactional calls from commercial communications
- Implementation follows consultations with Joint Committee of Regulators (JCoR)
- Approximately 485 entities have already adopted the series voluntarily
- Direction aims to reduce risks of fraudulent calls impersonating financial institutions
- Insurance sector mandates under discussion with IRDAI, to be notified separately
Regulatory Changes
1600-Series Numbering Mandate
