Singapore - Full SMS Sender ID Registration

On 31 January 2023, the Infocomm Media Development Authority (IMDA) implemented the Full  SMS Sender ID Registry Regime (Full SSIR Regime). The SSIR was set up to enable organisations to  protect their customers from receiving fraudulent SMS messages that spoof organisations’ SMS Sender IDs.

Under the Full SSIR Regime, organisations that wish to send SMS messages with alphanumeric Sender IDs to Singapore mobile subscribers must first register their Sender IDs with the SSIR.

To register the Sender ID with the SSIR, organisations will need to have a Singapore unique entity number (UEN) in order to register for Sender ID. Foreign-based businesses can obtain a Singapore UEN by registering with the Accounting and Corporate Regulatory Authority (ACRA).

Please contact the Singapore Network Information Centre (SGNIC) at smsregistry@sgnic.sg  or visit its website at https://www.sgnic.sg/smsregistry/overview  for the registration process.
