Do Not Call Registry & You

The Do Not Call (DNC) Registry lets you opt out of marketing messages addressed to your Singapore telephone number, such as those which promote or advertise a good or service, allowing you to have more control over the kind of messages you receive on your telephone, mobile phone or fax machine.

The DNC regime under the PDPA prohibits organisations from sending such messages to Singapore telephone numbers, including mobile, fixed-line, residential and business numbers, registered with the registry. 

Organisations which have an ongoing relationship with a subscriber or user of a Singapore telephone number may send marketing messages on similar or related products, services and memberships to that Singapore telephone number via text or fax without checking against the DNC Registry. Each exempt message must also contain an opt-out facility that you may use to opt out from receiving such telemarketing messages. If you opt out, organisations can no longer rely on the exemption and must stop sending such messages to your Singapore telephone number after 30 days.

The DNC Registry is meant to focus on telemarketing calls or messages of a commercial nature sent to consumers. Messages for pure market survey or research; messages that promote charitable or religious causes; personal messages sent by individuals; public messages sent by government agencies; and political messages will not be covered under the DNC provisions. Telemarketing calls or messages of a commercial nature that target other businesses are also excluded from the DNC provisions. For the list of messages that are excluded under the PDPA, please refer to the Eighth Schedule of the PDPA

You may register in any of the three DNC Registers, based on your preference:

  • No Voice Call Register;
  • No Text Message Register; and
  • No Fax Message Register.


You can still choose to receive marketing messages by certain organisations, simply by giving them your clear and unambiguous consent in written or other accessible form. Organisations that have obtained your consent may then send marketing messages to your Singapore telephone number, even if it is registered with the DNC Registry. If you change your mind, you will be able to withdraw your consent from the organisation concerned (subject to existing contracts).

Provisions relating to the DNC Registry came into effect on 2 January 2014.
