Sender ID Registration

Sender ID Registration is now required for all Sender IDs (ALPHA, ALPHANUMERIC, and NUMERIC-Only SIDs) for A2P SMS traffic to Singapore.

Singapore’s communication regulatory body Infocomm Media Development Authority (“IMDA”) released their decision to implement a mandatory SMS Sender ID Registry Regime (the “SSIR”), which will be fully enforced as of January 31, 2023.

All unregistered Sender IDs will be overwritten with “likely-SCAM” as a default during this period.

Bird, as one of the few registered service providers with the SSIR, is happy to inform you of the process and help you stay compliant.

What You Need To do

You should now be reserving and registering all Sender IDs through the SSIR Portal starting from February 1, 2023.

Here are the rules for SID Registration through the SSIR Portal:

  • Registration of Sender IDs is on a first-come-first-served basis.

  • No sharing of Sender IDs is allowed between user organisations.

  • Sender IDs cannot be transferred between user organisations, unless approved by SGNIC.

  • If a user organisation is seeking to register a Sender ID that is not linked to its company name or business, it may be requested to provide supporting documents to justify its choice of Sender ID.

  • Alphanumeric SIDs:

    • have a minimum of 3 characters and a maximum of 11 characters;

    • not contain non-Latin characters;

    • be in any combination of upper/lower casing;

    • not be generic in nature (for e.g. “OTP”, “SMS”, etc);

    • not be sensitive in nature;

    • not contain leading or trailing spaces;

  • Numeric SIDs:

    • Can either be a Singapore Short code (5-digit number in the series 7xxxx) or a Long code (8-digit LVNs from the 8 and 9 series) that is unique to the organisation

    • The user organisation will need to submit supporting document(s) to the SSIR, showing that the number was issued by a Singapore Mobile Network Operator (MNO) to the SMS aggregator that the user organisation is working with. MessageBird provides you an invoice as proof that the number is exclusively assigned to your organisation.

  • Fees & Billing of SSIR

    • There will be a one-time setup fee of S$500 for each registered organisation, and an annual charge of S$200 for each registered Sender ID. Prices are listed before prevailing Goods & Services Tax.

    • 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.

You will then need to provide the following additional documentation to MessageBird for any sender ID that you have registered in the SSIR portal no later than January 27, 2023:

  • Please ensure you have a valid Unique Entity Number (UEN) issued by the relevant Singapore government agency with a pdf export of your ACRA business registration. Foreign companies can receive one by registering at the Accounting and Corporate Regulatory Authority (“ACRA”).

  • Submit the following to Bird’s support team:

    • A copy of the ACRA Business Registration

    • a complete Alphanumeric request form for each Sender ID

    • an Email confirmation from the SSIR that your Sender ID is registered on the SSIR

    • For 3rd Party Representatives, please submit a Letter of Authorization from the organisation allowing you to carry their SMS traffic with their fully registered SIDs. Template of the Letter of Authorisation can be downloaded from here.
