Please be aware that the initial 6-month transition period, which began on January 31, 2023, has been extended beyond August 1, 2023. During this extended period, all unregistered Sender IDs will be labeled as "Likely-SCAM" and will remain permissible until further notice from IMDA.

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. All nonregistered Sender IDs will be marked as "Likely-SCAM" for a transitionary period for 6 months. This has been extended beyond August 1, 2023. During this extended period, all unregistered Sender IDs will be labeled as "Likely-SCAM" and will remain permissible until further notice from IMDA.

If your company is currently sending SMS messages with alphanumeric Sender IDs to Singapore mobile subscribers, you may wish to register your Sender ID(s) early in order to avoid any disruption to your SMS communications with your customers.

Organisations will need to have a Singapore unique entity number ("UEN") to register for a 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 for more information on the registration process
