Registration with the Do Not Call (DNC) Registry is free and simple. You should expect to stop receiving unsolicited telemarketing messages through your registered telephone number 21 calendar days after registration.

There are three methods to register:

1. Online @ www.dnc.gov.sg 

2. SMS 
Send an SMS with the message "DNC" to 78771. You can only register the number that you SMS from and SMS charges will apply.

3. Phone 
Call the toll-free number 1800 248 0771. You can only register the number that you call from. This number must not be subscribed to caller-ID blocking service.

Tip: If yours is not a fax number, please also add your number to the No Fax Message Register.

Your registration does not expire unless you terminate your telephone number or if you deregister your telephone number from the DNC Register(s). You may deregister at any time.
