TRAI introduced the designated 140 series for promotional calls to ensure that such calls originate from a dedicated numbering series, enabling consumers to easily identify and manage such calls. The calls originating from 140 series numbers are pre-verified against the preferences of the customers before delivery. The designated series enables the consumer to exercise the choice of accepting or declining the call.
The 1600 series was introduced for service and transactional calls by the entities in Banking, Financial services & Insurance sector, and for Government to citizen communication. This designated series provides trusted calling numbers for such important communications.

AI-Based Suspected Spam Flagging on Incoming Calls
In order to alert the consumers from suspected spam calls and SMS from entities using normal 10-digit numbers that bypass the regulated system, AI-based systems have been deployed by the Telecom Service providers (TSPs) to flag such suspected spam on the basis of calling pattern analysis. Further, the telecom service providers have started sending warning notifications to entities suspected with high probability of sending such spam. An entity could be using multiple numbers for sending spam. These notifications warn the suspected senders of regulatory action so as to refrain from sending further spam.
