The National Stock Exchange (NSE) on November 24, 2025, issued a circular regarding adherence to TRAI Direction dated November 19, 2025 – Mandatory Phase-wise Adoption of 1600-Series Numbers.
The following has been stated: -
•TRAI has issued a Direction (19 Nov 2025) mandating phased adoption of the 1600-series for all service and transactional voice calls by RBI, SEBI, and PFRDA-regulated entities.
•The move follows rising misuse of 10-digit numbers and DoT’s dedicated allocation of the 1600 series for Government/BFSI.
•QSBs must adopt the 1600-series by March 15, 2026, while other SEBI-registered intermediaries may adopt voluntarily for now.
•Post-deadline, non-adopting entities will face action as unregistered telemarketers, and no service/transactional calls may be made from non-1600 numbers.
