TRAI has clarified the regulatory position on 1600 series and 140 series numbers under the Telecom Commercial Communications Customer Preference Regulation (TCCCPR). The clarification is intended to prevent misinformation about how these designated numbering series are used, blocked, or filtered.
The change is important because the numbering series are part of a consumer-protection framework for commercial communications. TRAI has said that tagging, blocking, or filtering of calls from 1600 series numbers is not permitted, while 140 series numbers remain subject to consumer preference controls through the Do Not Disturb (DND) registry.
