How to fully or partially block telemarketing calls / SMS

To curb the growing menace and effectively regulate unsolicited commercial calls and messages, Telecom Regulatory Authority of India (TRAI)  has notified "The Telecom Commercial Communication Customer Preference Regulations, 2010". The regulations comes into effect from  27th Sep. 2011.

Customers (landline and mobile) who do not want to receive commercial communications can dial or SMS to 1909 (toll free) and register in either of the two categories:

Fully Blocked Category- stoppage of all commercial Calls/SMS
Partially Blocked Category- stoppage of all commercial Calls/SMS except SMS from one of the opted preferences

For registering option using SMS, for 'fully blocked category', write "START 0" and send it to 1909.

For 'partially blocked category', send SMS 'START' with one or multiple options from the list of seven categories.

There are at present 7 preferences to choose from-

Banking/Insurance/Financial Products/Credit Cards-1,

Real Estate-2,



Consumer goods and automobiles-5,



Examples - To receive messages relating to only Health products, then send SMS "START 4" to 1909. Similarly, for receiving messages relating to Real Estate and Education, send SMS "START 2,3" to 1909.

On successful registration, customer will receive an SMS confirming exercised options and a Unique Registration Number within 24 hrs. The registration will be effective within 7 days of placing the request with the service provider. Subscriber can check the status of their registration in NDNC Registry by clicking on "DND Registration Check"

Customers can also de-register their request for NDNC registry by dialing 1909 or SMS to 1909 STOP

If customer receives Unsolicited Commercial Communication (UCC) even after 7 days of registration, he can register a complaint with his service provider within 3 days of receipt of such UCC by dialing or sending SMS to 1909. Customers will have to provide the telephone number or header of the message from where the call or message has been received along with the date and time.

For complaint through SMS, customer has to send SMS COMP TEL NO XXXXXXXXXX, dd/mm/yy, Time hh:mm to 1909. Where XXXXXXXXXX - is the telephone number or header of the SMS, from which the UCC has originated.

Service Provider will take action on complaint and inform the complainant within 7 days of lodging of complaint. Customers may check registration status of his complaint through the link "UCC Complaint Registration Status".

Customers not registered with NCPR can also identify the commercial calls because they will all come from numbers starting with '140'. This is a series specially earmarked for telemarketers.

Also, in order to control the possibility of SMS packages (those allow a very large number of SMS per day) to be used by the telemarketers for sending large number of SMSs from a normal telephone number, a limit of 100 SMS per day per SIM has been laid down under these regulations except on blackout days.

Further, all commercial calls or SMS except the transactional SMSs will be sent to the customers only between 9 AM and 9 PM.

Does this also mean that regular users also have a limit of 100 SMS a day? If so, then this is a bad move. Its like limiting e-mail to 100 a day because of spammers.
