Implementation of Full SMS Sender ID Registration (SSIR) Regime by Infocomm Media Development Authority (“IMDA”)

What you need to know

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. For more information, please visit here.

The message from IMDA is available here.

All companies who send SMS with SenderID will be required to register the SenderID with Singapore Sender ID Registry (SSIR) for the SMS messages to be sent successfully.

We strongly advise all sendQuick customers to register with Singapore Network Information Centre (“SGNIC”) via the SSIR portal from 31st October 2022. This is to ensure there is no service disruption to your SMS service to your customers. This also increase the chance of registering your desired SenderID as it is given on a first-come-first-serve basis.

Please prepare the following for your registration

  • Your company’s registered name (based on ACRA), registered address & Unique Entity Number (UEN)*
  • Full name, contact number & email address of the person designated as your company’s Admin account holder in the SSIR portal
  • List of Sender IDs you intend to reserve for your organisation
  • Organisation’s Corppass for company verification purposes. If you do not have Corppass, SSIR may require your organisation’s utility bills or telecom bills.

* Foreign-based businesses can obtain a Singapore UEN by registering with the Accounting and Corporate Regulatory Authority (“ACRA”).

*Other non-business Organisations (e.g., charity organisation, societies, religious bodies) can also register with the relevant agencies that will issue UEN to these specific types of organisations.

According to IMDA guideline, messages with non-registered sender ID(s) by 31st January 2023 will need to have a SenderID named “Likely-SCAM” for a transitionary period of around 6 months. These SMS will be blocked after the transitionary period.

We encourage all SendQuick customers to duly apply for the SenderID from 31 October 2022 onwards. If you have any questions, please feel free to refer to our SSIR FAQ at You can also contact us at if you need any assistance.

    Frequently Asked Questions

    Full SMS SenderID Registration (SSIR)

    For sending to Singapore Numbers only
    SenderID is the name that appears in the SMS from field, when the recipient receives the SMS. The term SenderID is the same as CallerID that was used in our SMS service on the cloud. We are using SenderID/Sender Name and CallerID interchangeably and they mean the same item.

    Under the Full SSIR Regime, all organisations wishing to send SMS messages to Singapore mobile numbers must register any alphanumeric Sender IDs that the organisations use. Organisations can create an account and reserve their Sender IDs via the SSIR Portal. Reservation of Sender IDs will be on a first-come-first-served basis. Further information on the SSIR portal can be found here. (

    The full SSIR Regime has kicked in since 31 January 2023. All non-registered Sender IDs are now marked as “Likely-SCAM” as a default until further notice from IMDA.

    You will need to create an account on the SSIR portal. After your account is created, SGNIC will process your application. Once your account has been approved, your Admin account holder will receive an email notification. You will thereafter be able to log-in to the portal and reserve your preferred Sender IDs. The Admin account holder in the portal will be able to create other User accounts for your organisation. Further information on the SSIR portal will be made available soon.

    All Organisations that send SMS with Sender IDs must first present a valid identification, i.e., the local unique entity number (“UEN”), as issued by relevant government agencies. Organisations with the valid identification (i.e., the UEN) can then register with the SSIR, and protect the Sender IDs they wish to use when sending SMS to Singapore mobile users.

    Foreign-based businesses can obtain a UEN by registering with the Accounting and Corporate Regulatory Authority (“ACRA”). A foreign business can either register as local subsidiary or register as a foreign branch office. Foreign-based businesses can then register for Sender IDs with SSIR via their local subsidiary or foreign branch office as long as the local subsidiary/ foreign branch office can present a valid UEN. Companies registered with ACRA will have to comply with the statutory and disclosure requirements of the Companies Act.

    Other non-business Organisations (e.g., charity organisation, societies, religious bodies) can also register with the relevant agencies that will issue UEN to these specific types of organisations.


    An organisation may authorise a representative to send SMS with the organisation’s registered Sender ID on its behalf. For example, a marketing firm is appointed by an organisation to run a marketing campaign for the organisation. To authorise the representative to send such SMS with the registered Sender ID on the organisation’s behalf, a Letter of Authorisation (LoA) provided by the organisation who registered that Sender ID is required. The representative will need to provide the LoA to the participating aggregator engaged for the sending of the SMS.

    You can download the template of the LOA here.


    The SenderID is registered to your account and messages not using the same SenderID will not be sent. In sendQuickASP, all customers are only allowed to send messages belonging to their own SenderID.

    Any whitelisting protection by the Registry will be applied to Singapore mobile numbers only. Organisations can choose to deliver such SMS messages carrying registered Sender IDs to foreign mobile numbers. However, foreign recipients may still receive SMS which spoof your Sender ID, if the messages pass through non-participating aggregators.


    There are fees which are charged and billed by SGNIC. It consists 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. SGNIC may review the fees periodically and users will be informed in advance prior to any fee changes.


    SGNIC will allow companies time to transition to the Full SSIR Regime. 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, where an invoice will be emailed to the registered user organisation’s designated billing contact.


    Each SenderID must follow the following guidelines:

    • Up to a maximum of 11 alphanumeric characters, including space and are Case sensitive (note: due to varying formatting in individual mobile phones for the SMS service, it is strongly advisable to keep the SenderID up to 11 alphanumeric characters only)
      • E.g. SENDQUICK and sendquick are two different SenderIDs
    • Shortcode (e.g. 7XXXX) is acceptable
    • Presence of space will differentiate the SenderID
      • E.g. SENDQUICK and SENDQUIC K are two different SenderIDs
    • All generic sender IDs (e.g., Sales, Reminder, OTP, SMSOTP) will be rejected
    • All Chinese or Cyrillic characters will be rejected too
