TRAI initiates phase-wise implementation of 1601-series for service and transactional calls by utilities, courier and logistics sectors entities

The Telecom Regulatory Authority of India (TRAI) has issued a Direction to allocate 1601‑series numbers for service and transactional voice calls by entities in sectors other than Banking, Financial Services & Insurance (BFSI) and Government. Phase‑I targets utilities (electricity, water, city gas, LPG) and logistics/courier services, with Telecom Service Providers (TSPs) required to verify eligibility and complete onboarding within 90 days. The numbers will be assigned directly to eligible entities, not intermediaries, and must be used exclusively for service/transactional calls, not promotional calls, aiming to curb impersonation and enhance consumer trust in voice communications.
