TRAI and DND
TRAI's commercial communication rules (TCCCPR, amended in 2025) cover business calls. Numbers on the DND registry must not get promotional calls unless the person has consented. Service and transactional calls about a customer's own account or order rely on the existing relationship, but must stay about that service. Under the 2025 amendment, promotional calls use the 140 number series, service and transactional calls use the 1600 series, and ordinary 10-digit numbers must not be used for telemarketing (TRAI, Feb 2025). Banks, NBFCs and other financial firms had 1600-series deadlines in early 2026.
DPDP Act, 2023
India's data protection law. Collect personal data for a clear purpose with notice and consent, let people withdraw consent, and delete data you no longer need. The DPDP Rules were notified on 14 November 2025, with most duties phased in over 18 months (PIB). For the calls you run, your business decides who is called and why.
RBI rules for loan recovery
Recovery calls are allowed only between 8 am and 7 pm unless the borrower asks otherwise, and intimidation is banned. RBI's amended directions, issued on 6 August 2026 and in force from 1 January 2027, also require lenders to record the content of recovery calls and tell the borrower the call is recorded (RBI, 2026; parallel directions cover NBFCs and other lenders). Lenders should run their EMI reminder and collection call campaigns within these hours.
Insurance and real estate
Insurers follow IRDAI's rules on selling and servicing policies, and developers follow RERA on what they can promise. Keep AI scripts within the same limits your human team follows.
