NDNC Activate or Deactivate »

As we know, low tariffs and direct reach to consumers has made SMS and direct calling one of the most cost effective ways of selling services and products. However, telemarketing has brought with it serious issues of invasion of privacy and has become a major irritant to customers. If you wish to discontinue get unsolicited commercial Calls or SMS, TRAI has notified "The Telecom Commercial Communication Customer Preference Regulations, 2010". All the provisions of regulations come into force from 27th September, 2011.

To register in the National Do Not Call registry in India, do one of the following.

Send an SMS with the message START 0 to 1909 OR Call 1909 and follow instructions

Note: If the above SMS is not recognized, try sending the old format message START DND to 1909

You can call on 1909 from your mobile phone to register with National Do not call register. This number is toll-free.

Now you can also choose from the below preference(s) to receive/ stop calls or SMS:

Banking/ Insurance/ Financial products/ Credit Cards
Real Estate
Consumer goods & Automobile
Communication/ Broadcasting/ Entertainment/ IT
Tourism & Leisure

Eg: If you wish to start receiving Calls/ SMS related to Health, simply send "START 4" to 1909


If you wish to stop receiving calls/ SMS related to Real Estate, simply send "STOP 2" to 1909

Complain / Complaints

If you are getting Unsolicited Commercial Calls (UCC) even after a confirmed registration for Do Not Disturb (DND) at the NDNC/NCPR registry, you may complain to your service provider. Please note that TRAI or NDNC Registry doesn’t take complaints directly and it is your service provider who will handle these complaints.

Send an SMS in this format: COMP TEL NO XXXXXXXXXX;dd/mm/yy;hh:mm;short description to 1909

Here, XXXXXXXXXX is the number against which you are complaining or the sender code in case of bulk SMS without a number. The next two are date and 24-hour time at which you received the unsolicited message or call. At the end, add a short description of the call you received.

e.g. COMP TEL NO 9999900000;31/01/12;16:45;ABC Bank about loans

Alternately, call 1909 and follow instructions to register a complaint.
