TRAI’s New Voice Call Guidelines: 140 & 1600 Series Explained
To build a safer and spam-free communication ecosystem, TRAI has introduced TCCPR guidelines mandating specific number series for business calls:
- 140 Series (Promotional Calls): For marketing and outreach campaigns by businesses, enterprises, and telemarketers.
- 1600 Series (Transactional Calls): For regulated entities like banks, NBFCs, insurers, mutual funds, pension funds, and stockbrokers.
This structured approach ensures transparency, curbs spam, reduces fraud, and helps customers easily identify genuine calls.
Who Can Procure the 140 & 1600 Series?
-
140 Series (Promotional):
- For enterprises running promotional campaigns.
- Requires registration on the DLT platform with approved voice templates.
-
1600 Series (Transactional):
- For regulated BFSI and investment entities under RBI, SEBI, IRDAI, and PFRDA.
- Used for OTPs, payment reminders, alerts, and policy updates.
Industry-Wise Implementation

- Stockbroking & Investments – Trade confirmations, portfolio alerts, settlement notifications via 1600 series.
