TRAI Launches '1600' Number Series to Strengthen Security of Banking and Financial Calls in India 🔐

In a landmark move to combat the growing threat of financial fraud through scam calls, the Telecom Regulatory Authority of India (TRAI) has officially launched a dedicated '1600' number series. This number series will be exclusively used by regulated financial entities — such as banks, insurance companies, and stock brokers — to make genuine service and transactional calls.

🚨 The Problem: Rise in Banking Fraud via Phone Calls

Over the past few years, fraudulent calls pretending to be from financial institutions have increased significantly. These scams often involve data theft, OTP phishing, or direct financial loss.

Until now, there was no simple way for customers to verify the legitimacy of such calls. Even genuine service calls were ignored because they appeared to come from random or suspicious numbers.

✅ TRAI’s Solution: A Secure '1600' Number Series

Only DLT-registered telemarketers will be allowed to use this '1600' prefix number series, which is reserved specifically for:

• 🏦 Banks


• 🛡️ Insurance Companies


• 📈 Stock Brokers


• 💰 Pension Fund Managers


• Other entities regulated by RBI, SEBI, IRDAI, or PFRDA

This will help customers instantly identify genuine calls from these entities.

🧩 How Will the '1600' Number Series Work?

The new format will resemble:

1600ABXXXX

• AB: Represents Circle and Operator Code


• XXXX: Unique ID of the financial entity

This structure ensures traceability, transparency, and better caller identity. SBI Card and others have already begun using this new series to improve customer confidence.

🔐 Why This Is a Game-Changer

• Prevents Scam Calls — Customers can instantly verify authenticity.


• Boosts Trust — Legitimate calls won't be flagged as spam.


• DLT Compliance — Only registered, verified businesses can use the number series.


• Strengthens Digital India — Supports the growing fintech ecosystem with security-first infrastructure.

📈 What It Means for Consumers & Businesses

✅ For consumers: Stronger protection against scam calls.

✅ For businesses: Increased call answer rates, reduced service disruptions, and improved brand credibility.

TRAI’s move is a bold and proactive step toward making financial communications safer in India.

📢 Final Thoughts

The 1600 number series is not just a telecom update — it’s a revolutionary safeguard for India’s digital banking future.

💡 Pro Tip: If a call starts with 1600, it's likely from your bank or insurer. It's trustworthy — but always be cautious when sharing information.
