Full SMS Sender ID Registration Regime starting from 31 January 2023

The Infocomm Media Development Authority (“IMDA”) has announced that it will be implementing the Full SMS Sender ID Registration (“Full SSIR Regime”) starting from 31 January 2023.

Under the Full SSIR Regime, organisations that wish to send SMS messages with alphanumeric Sender IDs must first register their Sender IDs with the SSIR. Only registered Sender IDs will reach Singapore users with effect from 31 January 2023. All non-registered Sender-IDs will be channelled to a Sender ID bearing the name “Likely-SCAM” for a transitionary period of around 6 months. These SMS will be blocked after the transitionary period.


If you have a SMS SenderID setup with CommzGate for sending SMS messages with alphanumeric Sender IDs to Singapore mobile numbers and have not registered your SenderID, you must register your Sender ID early in order to avoid any disruption to your SMS communications with your customers.


As this registration is managed by IMDA subsidiary Singapore Network Information Centre ("SGNIC”), you need to contact SGNIC at or visit its website at  for more information on the registration process. Please note that there are fees charged directly by SGNIC for this registration. Organisations will need to have a Singapore unique entity number (“UEN”) in order to register for a Sender ID. Foreign-based businesses can obtain a Singapore UEN by registering with the Accounting and Corporate Regulatory Authority (“ACRA”).


IMPORTANT: You can reserve your Sender IDs via the SSIR portal on a first-come-first-served basis. Reservation of Sender IDs for the Full SSIR Regime will be at no cost from 31 October 2022 to 30 January 2023. SSIR will commence billing organisations for their setup fee and Sender IDs from 1 February 2023 onwards.
