Do Not Disturb/Call Me, TRAI NCPR Regulation

In 2007, Telecom Regulatory Authority of India (TRAI) set up National Do Not Call (NDNC, also called as do not disturb, DND) Registry to curb unsolicited Commercial calls. i.e. any call/message, through telecom system promoting any commercial transaction for goods, investments or services, which a subscriber does not wish to receive.

It failed to help customers and in 2011, TRAI came up with new policy with name National Customer Preference Register (NCPR) and it became operational on 27th Sept, 2011.

Mobile phone users who want to register their phone number for Do not call registry may dial 1909 or SMS to 1909 with keywords ‘START 0‘ for registration and ‘STOP DND‘ for de-registration. Requests will become effective in 7 days from the date of request.

Partial Blocking: Apart from normal full blocking of telemarketing calls, subscriber now will also be able to opt for partially blocked mode, which will allow to receive promotions for specific categories like real estate, education, finance,  entertainment, health and tourism etc. This seperate list will be now called as National Customer Preference Register (NCPR).  By default, all subscribers will be moved to fully blocked mode. For partial blocking, SMS needs to sent to 1909 will be ‘START Option-Code’ and ‘STOP Option-Code’ . Once changed, preference cannot be changed for next 3 months.

Option code for each category is provided below:

  1. Banking/Insurance/Financial products/credit cards
  2. Real Estate
  3. Education
  4. Health
  5. Consumer goods and automobiles
  6. Communication/Broadcasting/Entertainment/IT
  7. Tourism and Leisure

So if you want to receive messages relating to only Banking products, then send SMS “START 1” to 1909. Similarly, for receiving messages relating to Health and Education, send SMS “START 4,3” to 1909.

Phone subscribers can check the status of their registration in Commercial Communications Customer Preference Registry here.

How to complain: In case subscriber still receives call/messaes, he should complain to mobile service provider, mentioning the caller/sender telephone number, date/time of the call and details of message. All complaints must be actioned upon within 7 days.

If you receive any unsolicited commercial communications seven days after registration of your telephone number in the NCPR, you may register a complaint by:

  1. Dialling the toll free number 1909; or
  2. Sending an SMS to 1909

TRAI has announced to minimize unsolicited calls by penalizing telemarketing firms and operators with hefty fine.

From Sept 2011, all telemarketer’s calling numbers will start with ‘140‘. All telemarketing must get special phone numbers starting from ‘140’ series, so that mobile phone user may decide to accept or reject just by looking the caller phone number. If some telemarketer calls from any other number (not starting with 140), he may be fined with hefty penalty.

TRAI has proposed fine from 25,000 upto 2.5 lakh (depending on number of times complaint has been registered) on telemarketing firms against whom complaints have been received.

Mobile service provide maybe fined upto Rs 10 lakhs, if there are four times complaints.

Mobile phone subscribers (non tele-marketers) can now only send maximum 100 SMS in a day. It will stop marketers to use mobile numbers not registered as tele-marketers and will force them to get a separate marketer number.

Every telemarketer will have to deposit 10,000 (9,000 for customer education and 1,000 as registration fee) for registration. Also a security deposit of Rupees 1 Lac, also will have to deposited. Any fines on telemarketer will also be deducted from this security amount.

Commercial messages can only be sent during 9am till 9pm only.

Mobile phone operator will be managing customer preferences at their end and filter out SMS/Phone calls based on subscriber registration status.

  1. Dear Sir,
    On 18/2/12 at around 11am we received a call from 01409450154 on our landline We are based at Karaikal but originally from Kerala). My son (who doesn’t know Tamil) picked it up and was greeted with a volley of Tamil from a woman. My son was so flustered that he kept down the phone and informed us. Immediately another call from the same no. 01409450154 came and this time I picked it up. Again a woman started speaking in Tamil asking who it was who picked up the phone earlier. I (knowing some Tamil) responded, asking her to introduce herself. However she just instructed me (again in Tamil) to teach the earlier person some manners & how to respond to calls and then she herself cut the call before I could explain the situation.
    Kindly advice to whom should I complain?

  2. PHONE NO>:01409450154

    Its whose no. can anybbody tells us. I am getting lot of missed calls from this no on my landline.


  4. CUSTOMER CARE EXECUTIVE at 1909 informed me that they can not do any thing if the call received from mobile phone. They could do some thing only if it is land lain. He asked me to complain in TRAI web site. I could not locate complaining facility in TRAI web site. Could anybody advice?

Further i want to proceed Legally, To whom may i proceed to complaint?

    • @Srinivasulu
      Unfortunately, there is nothing you can do.
      I am filing almost a complaint everyday on 1909, but nothing happens.
      I have filed closed to 1000 such complaints, but nobody got fined ever. I only get responses like subscriber disconnected, record does not match etc.

      • I registered my 3 numbers for complete DND on NCPR on 28 th August 2015. It was activated on 30 th August. Since then I haven’t received a single commercial call or message in any of my 3 numbers. So what do you feel, DND has started to work or happy days are going to end soon ? Love to hear from you.

  11. I have activated DND service but after activation I have received teli marketing call and sms. My telicom orater aircel
    And 1909 no not conting from my aircel no
    Please help me

  12. I had activated DND the day the announcement regarding this was made.
    I’ve been using both prepaid and postpaid numbers.
    Still getting marketing calls and messages on both the numbers even though full DND is activated. I have made n no of complaints and got so many complaint numbers too. Still i continue getting marketing calls n sms. On approaching vodafone they say that they are helpless and can only provide me a new vodafone number.
    This is a very surprising reply.
    Kindly guide me how shall i escalate this issue with TRAI so that proper actions can be taken by vodafone.
