TRAI’s Latest Clarification

TRAI has clarified that:

1600 series numbers should not be tagged, blocked, or filtered as spam because they are reserved for legitimate service communications.
140 series numbers are used for promotional calls. Customers can reduce these through the Do Not Disturb (DND) service, but telecom providers and apps should not arbitrarily tag or filter these designated number ranges outside the regulatory framework.

Safety Tips for Mobile Users

Always verify the identity of callers claiming to represent banks or government agencies.
Never share your OTP, UPI PIN, passwords, CVV, or internet banking credentials over the phone.
Be cautious even if a caller appears to use an official number.
Report suspicious calls to the appropriate authorities or your telecom operator.

Conclusion

The introduction of the 1600 number series and the continued regulation of the 140 number series are significant steps toward making India’s telecom ecosystem safer and more transparent. While 1600 numbers are meant for genuine service-related communication, 140 numbers are reserved for promotional calls. Knowing the difference helps consumers make informed decisions and stay protected from fraud while ensuring they do not miss important communications.
