Phone calls from 1600 number series cannot be blocked as ‘spam’, TRAI clarifies amid row over Truecaller, other apps

The Telecom Regulatory Authority of India (TRAI) has clarified that calls from the 1600 series cannot be automatically marked as spam, which caused confusion amid debates involving apps like Truecaller. While the Do Not Disturb (DND) app can block calls from the 140 series, it doesn't extend to the 1600 series. This ruling is important as it impacts how users manage incoming calls and could affect the functionality of caller identification apps. The clarification aims to ensure users aren't inadvertently blocking essential business communications.
