Trai: 1600 Series Calls Can't Be Blocked
Regulated entities' calls can't be blocked, but 140 series can be.

The Telecom Regulatory Authority of India (Trai) has stated that calls from the 1600 number series cannot be blocked by any application. This series is reserved for regulated entities and government communications, which are considered trustworthy.
These calls are typically related to service and transaction updates for existing customers. As a result, they are exempt from being blocked.
On the other hand, promotional calls from the 140 series can be blocked using the Do Not Disturb (DND) registry. Registered telemarketers use this number series to send promotional communications to customers.
Customers have the option to register their preferences on the DND registry, allowing them to either receive or block these promotional calls. This provides customers with control over the types of calls they receive.
The 1600 number series is mandated by Trai for trustworthy service and transaction calls. This is to ensure that customers receive important updates and communications from regulated entities without any interruptions.
The DND registry is a tool that helps customers manage unwanted calls and messages. By registering on the DND registry, customers can avoid receiving promotional calls and messages from telemarketers.
Trai's regulations aim to strike a balance between allowing customers to receive important communications and protecting them from unwanted promotional calls.
The distinction between the 1600 and 140 number series is crucial in understanding which calls can be blocked and which cannot. While calls from regulated entities cannot be blocked, customers have the option to manage promotional calls from registered telemarketers.
In summary, Trai's regulations provide a framework for customers to manage their communications preferences. By understanding the difference between the 1600 and 140 number series, customers can make informed decisions about which calls to receive and which to block.
This development is significant for customers who value their privacy and want to manage their communications effectively. With Trai's regulations in place, customers can enjoy a better experience when it comes to receiving calls and messages.
