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 organizations to protect their customers from receiving fraudulent SMS messages that spoof organizations’ SMS sender IDs. 

Under the Full SSIR Regime, organizations that wish to send SMS messages with alphanumeric sender IDs to Singapore mobile subscribers must first register their sender IDs with the SSIR. All non-registered sender IDs will be marked as “Likely-SCAM” for a transitionary period of 6 months.  

After that, SMS messages with non-registered sender IDs will be blocked and not delivered to mobile subscribers in Singapore.

Clickatell is working with our partners to facilitate a solution to ensure our customers’ service continues and will provide the next steps for our customers shortly.
