RBI’s New Banking Rule: Here’s How to Identify Genuine Bank Calls from Scams in 2025

RBI's New '1600' and '140' Rule
The Reserve Bank of India introduces dedicated number series starting with '1600' and '140' to combat financial fraud and protect consumers from scam calls

In a landmark decision aimed at protecting millions of Indian consumers from financial fraud, the Reserve Bank of India (RBI) has mandated that banks can now only use two specific number series for all their customer communications. This revolutionary step comes as a response to the rising tide of banking-related spam calls and financial scams plaguing mobile users across the country.

Key Highlights

  • Numbers starting with ‘1600’: Reserved for all transaction-related communications
  • Numbers beginning with ‘140’: Designated for promotional calls and marketing SMS
  • Implementation: Effective immediately across all banking institutions

The new system creates a clear distinction between legitimate banking communications and potential scam calls, making it significantly easier for consumers to identify authentic bank contacts. Under the new guidelines:

Transaction-Related Communications (1600 series)

  • Account updates
  • Transaction alerts
  • Security notifications
  • Account-specific information

Marketing Communications (140 series)

  • Credit card offers
  • Personal loan promotions
  • Insurance products
  • Other banking services

“This initiative represents a significant step forward in protecting consumers from financial fraud,” said a senior RBI official. “By standardizing the communication channels, we’re making it virtually impossible for scammers to impersonate legitimate banking institutions.”

Impact on Consumers

  • Enhanced security against fraudulent calls
  • Easy identification of genuine bank communications
  • Reduced risk of falling victim to financial scams
  • Greater confidence in banking communications

The move comes at a crucial time when digital banking fraud has seen a sharp increase, with scammers often posing as bank representatives to deceive customers. The standardized number system creates a clear, foolproof way for customers to verify the authenticity of banking communications.

Consumer Advisory

  • Always verify that transaction-related calls come from numbers starting with 1600
  • Marketing calls should only come from numbers beginning with 140
  • Report any suspicious calls claiming to be from banks but using different number series
  • Never share sensitive financial information over phone calls
