This topic describes the announcement on the sender ID registration regulations issued by the Infocomm Media Development Authority (IMDA) in Singapore.

IMDA has announced that it will implement the SMS Sender ID Registry (SSIR) registration from January 31, 2023.

Take note of the following information:

  • Enterprises that use alphanumeric sender IDs must complete SSIR registration at the earliest opportunity.

  • Starting from January 31, 2023, senders who have registered their sender IDs can normally display their sender IDs when sending SMS messages to Singapore customers, whereas all non-registered sender IDs will be replaced with a sender ID named "Likely-SCAM".

  • Enterprises must register with the SSIR by using their Unique Entity Number (UEN). Foreign enterprises can obtain a Singapore UEN by registering with the Accounting and Corporate Regulatory Authority (ACRA).

Important
  • If your enterprise sends SMS messages with an alphanumeric sender ID to Singapore customers, we recommend that you register your sender ID at the earliest opportunity to avoid any disruption to your SMS communication with your customers.

  • For more information about the SSIR registration, contact the Singapore Network Information Centre (SGNIC) at smsregistry@sgnic.sg or visit its website at https://sgnic.sg.
