The DNC provisions of the PDPA generally prohibit organisations from sending marketing messages (in the form of voice calls, text or fax messages) of a commercial nature to Singapore telephone numbers, including mobile, fixed-line, residential and business numbers, registered with the DNC Registry, unless the consumer has provided their clear and unambiguous consent in written or other accessible form for sending the marketing message to the Singapore telephone number.
The organisation may still send a direct marketing message where the sole purpose of the message is:
- to facilitate, complete or confirm an earlier transaction between the sender and recipient;
- to provide warranty information, product recall information, or safety or security information with respect to a product/service purchased by the recipient;
- to deliver goods or services that the recipient is entitled to receive under an existing transaction; or
- related to the subject matter of an ongoing relationship between the sender and the recipient.
Individuals may subsequently opt out of receiving direct marketing messages. Upon receiving an individual’s opt-out request, the organisation must stop sending such messages to that individual's telephone number 21 days after the opt-out.
Under the PDPA, organisations are not permitted to send, cause to be sent or authorise to send any message with a Singapore link to telephone numbers generated or obtained through the use of a dictionary attack or address harvesting software. This prohibition also applies with respect to electronic messages generated or obtained through the use of a dictionary attack or address harvesting software under the Spam Control Act.
In addition, under the Spam Control Act, organisations are prohibited to send, cause to be sent or authorise to send any unsolicited commercial electronic messages in bulk if they do not comply with the statutory conditions (e.g. the message needs to include an email address to which the recipient may submit an unsubscribe request).
