The Telecom Regulatory Authority of India (TRAI) has been continuously strengthening regulations to establish a secure and spam-free communication ecosystem in India. To ensure that consumers receive only consented and authenticated communication, TRAI has streamlined number series allocations 140 for promotional and marketing calls and 1600 exclusively for service and transactional calls made by regulated BFSI entities. This step aims to curb fraud, spoofing and unsolicited commercial calls, while enabling citizens to instantly identify legitimate communication from banks, insurance firms and other financial institutions.

TRAI has now issued final deadlines for the mandatory adoption of the 1600 series by banks, NBFCs, mutual funds/AMCs, stock brokers and other regulated entities. Although the earlier expected migration timeline was November 2025, the deadlines have been extended due to delayed awareness and slower execution across the sector. Under the phased implementation approach:

• Banks (RBI regulated) → 1 January 2026
• AMCs / NBFCs / Payments Banks / Small Finance Banks → 1 February 2026
• Qualified Stock Brokers → 15 March 2026

After the deadline, any service and transactional customer calls using regular 10-digit numbers will not be permitted. Organizations may face disruption and non-compliance risks if the migration is not completed on time.

Why the 1600 Series Matters for BFSI

The transition to the 1600 series is not merely a regulatory obligation; it is a strategic improvement in customer communication. This initiative is expected to:

• Boost customer trust with a clear and consistent caller identity
• Reduce fraud and impersonation attempts significantly
• Improve call answer rates as customers recognize legitimate financial calls
• Enhance transparency and brand reliability for institutions

In a rapidly digitalizing financial ecosystem, secure communication plays a vital role in customer experience. The 1600 series will become a strong layer of verification for consumers, especially senior citizens and rural populations who are more vulnerable to cyber fraud.

Key Requirements for BFSI Entities to Migrate to 1600 Series

To ensure a smooth shift from 10-digit calling to the 1600 series, organizations need to prepare for the following:

• Procurement of the 1600 number series from an authorized VNO-licensed provider
• Updating call flows across hosted IVR, cloud call centre dialers, CRM and APIs
• Mapping 1600 numbers in DLT headers and consent mechanisms
• Testing outbound and inbound connectivity across customer segments
• Ensuring business continuity and high call connect ratios during the transition

Because several departments like technology, operations, compliance and customer service are involved, timely planning is essential to avoid last-moment implementation challenges.
