What is the Full SSIR Regime?
Under the Full SSIR Regime, all organisations wishing to send SMS messages to Singapore mobile numbers must register any alpha/numeric/alphanumeric Sender IDs that the organisations use. From 31 October 2022 to 30 January 2023, organisations can create an account and register their Sender IDs via the SSIR Portal. Registration of Sender IDs will be on a first-come-first-served basis following the Rules of Registration.

From 31 January 2023 onwards, when the Full SSIR Regime kicks in, all non-registered Sender IDs will be marked as “Likely-SCAM”.
What is the process for signing up with the Registry?
You will need to create an account on the SSIR portal#. SGNIC will process and verify your application, which will typically be completed within two working days*. Once your account has been approved, you will be able to log-in to the portal and register your Sender ID(s). The whitelisted^ Sender ID(s) will thereafter be conveyed to the Participating Aggregators on a weekly basis. It may take up to nine working days to commence protection of the whitelisted Sender ID(s) upon approval.
 
*Provided that your submission is completed with ALL supporting documents such as Corppass verification and the Participating Aggregators that your organisation works with.
 
^More time will be needed to register your Sender ID(s) if they are not unique to your organisation’s brand/product, please provide supporting document such as website, screenshots, product brochures, collateral, etc.

Can foreign companies or non-business Organisations sign up with the SSIR? 
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 in Singapore. 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. 

A Letter of Authorisation (LOA) can be issued by the Singapore-registered subsidiary/foreign branch office to authorise other overseas branch offices, which need to send SMS with SSIR registered Sender IDs on the local subsidiary/foreign branch office’s behalf. This copy of the completed LOA needs to be submitted by the foreign-based business to the participating aggregator(s) engaged for the SMS delivery to Singapore mobile users. The LOA template for affiliates can be downloaded here.

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. 
What is the cost of this service?
Please read the SSIR User Agreement and refer to the Annex: Fee and Fee Payment Schedule. 
How will I be billed? 
An invoice will be emailed to the registered user organisation’s designated billing contact.

SGNIC accepts payment via these digital payment modes:
  1. Interbank transfers (SGNIC bank details are provided on the invoice)
  2. PayNow through SGNIC Unique Entity Number (UEN): 199704146E
Please indicate the Invoice Number as the payment reference and email a copy of the payment advice to [email protected] for verification.

Can I request for a refund?

As stated in the SSIR User Agreement, Clause 4 and ANNEX: Fee and Fee Payment Schedule, the Sender ID annual fee for a Billing Year will not be pro-rated notwithstanding that a Sender ID is listed for less than a full calendar year. Users who remove any Sender ID will not be refunded for the remaining time in a Billing Year.

For the avoidance of doubt, there will be no refund under any circumstances, including cancellation of user account.

Can I ask SGNIC to register itself as a supplier in my company’s portal and send me the invoice through the portal?
SGNIC is a wholly-owned subsidiary of the Info-communications Media Development Authority (IMDA) and is undertaking the operation of the Singapore SMS Sender ID Registry (SSIR) in the public interest pursuant to a power delegated by IMDA. SGNIC and the SSIR user organisation have a User Agreement, therefore SGNIC will not execute or provide any other documentation or information, or complete other forms or questionnaires, or otherwise take any further steps in connection with any parties’ application for a SSIR user account. Hence, SGNIC will not be able to register itself in SSIR user organisation's finance/vendor/billing portal.

SGNIC will issue the invoice to the SSIR user organisation’s designated billing email address registered in the SSIR portal.

In order to facilitate payment, SGNIC will provide a corporate information pack, comprising of our ACRA business profile and bank account details including a confirmation letter from our banker. We trust that the information therein will be sufficient for SSIR user organisation to arrange the required payments to be made to SGNIC.
Who are the Participating Aggregators?
Participating Aggregators are SMS Aggregators licensed by the Infocommunications Media Development Authority (IMDA) to undertake the delivery of SMSes with Sender IDs registered with SGNIC. They are listed here.
What if my Aggregator is not on the list of Participating Aggregators?
Only Participating Aggregators (PAs) can handle registered whitelist Sender IDs. A PA must be licensed by IMDA. More information on IMDA’s application procedures and license criteria can be found at Services-Based Operations (SBO) Licence - Infocomm Media Development Authority (imda.gov.sg). You can reach out to SGNIC at [email protected] if your Aggregator is not one of the PAs. SGNIC can work with you to onboard them. Alternatively, if your Aggregator is not keen to participate in the Registry, you may have to reroute your traffic through other PAs to ensure that the whitelist protection works correctly.
What types of Sender IDs can be accepted by the Registry?
Each Sender ID cannot exceed 11 characters (including spaces, underscores or hyphens), cannot contain Chinese or Cyrillic characters, and should not be generic in nature. Please refer to Rules of Registration for more details.
Can I include the shortcode Sender ID I am using (e.g. 7XXXX)?

This is possible provided the following conditions are met:

  1. Only 5-digit short codes starting with 7 can be registered;
  2. The short code will need to be unique to the user organisation; and
  3. The user organisation will need to submit supporting document(s) to the SSIR, showing that the short code was issued by a Mobile Network Operator in Singapore to the SMS aggregator that the user organisation is working with.
Can I include the Long Virtual Number (LVN) Sender ID I am using (e.g. 8XXXXXX and/or 9XXXXXXX) ?

This is possible provided the following conditions are met:

  1. Only numeric Sender IDs assigned by Mobile Network Operators in Singapore and sent by Participating Aggregators can be registered. SIM card mobile number cannot be registered as Sender ID; 
  2. Only LVNs from the 8 and 9 series can be registered, where user organisation should register the 10-digit LVN (65 without "+" prefix) e.g. 658xxxxxxx or 659xxxxxxx.  The 8-digit LVN (without 65) e.g. 8xxxxxx or 9xxxxxxx will not be accepted for registration;
  3. The LVN will need to be unique to the user organisation;
  4. The user organisation will need to submit supporting document(s) to the SSIR, showing that the LVN was issued by a Mobile Network Operator in Singapore to the SMS aggregator that the user organisation is working with.
I have submitted my Sender IDs to the Registry and realized there was an error. How do I amend the error?
You can delete your submitted Sender ID via the portal and resubmit the correct Sender ID. Alternatively, you could reach out to SGNIC at [email protected].
Can I send SMS with registered Sender IDs to foreign mobile numbers?
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.
I have registered my Sender IDs with the Registry. Some of my customers are not receiving my SMS messages. What should I do?
You should engage your SMS aggregator to investigate the issue. You may wish to keep the Registry [email protected] in the loop when you check with your aggregator.

You are also advised to take note of the following steps when sending SMS to avoid the SMS being converted into the “Likely-SCAM” thread: 
 
1. Make sure whitelisting has been effected - While users may have submitted an application to register a Sender ID, they will be able to send SMS using the Sender ID only after the whitelisting is effected by your aggregators participating in the SSIR (see point 4 below). Doing so before the effective date will result in the SMS being converted to “Likely-SCAM”. For example, if a user sends an SMS with a Sender ID where the status of that ID is still pending, the Sender ID will be converted to "Likely-SCAM". Users can obtain information on whether their application is successful and when the whitelisting will be effective by from their SGNIC account (see screenshot below where the latest status shows “Live” and effective date under the “Effective By” column).  It takes some time for applications to be processed as your identity needs to be verified in order to maintain the security and integrity of the registry. 
 SID(Sent)

2. Sender IDs are case sensitive - Users should check their Sender IDs and ensure the Sender ID matches that of its whitelisted Sender ID before sending the SMS. To illustrate, “PineApple” and “PineAPPLE” are considered two different IDs. Using a Sender ID with a different upper/lower case format from that of the whitelisted Sender ID will result in the SMS being blocked or converted to “Likely-SCAM”. If users prefer to send using different Sender ID format i.e. upper/lower case, please register them with the SSIR.
 
3. Make sure all Sender IDs used have been whitelisted – Some users may use different Sender IDs for different types of SMS communications with their clients. Please ensure the Sender IDs used are whitelisted with the SSIR. If users are relying on service providers to send SMS and the SMS is sent using the Sender ID of the service providers, users should also check if their service providers have registered the Sender ID with the SSIR.  
 
4. Use only aggregators that are participating in the SSIR – We are aware of instances where users attempted to send their SMS with a whitelisted Sender ID through a SMS aggregator that is not participating in the SSIR. Please note that only aggregators that are participating in the SSIR (“Participating Aggregators”) are allowed to handle whitelisted Sender IDs. Whitelisted Sender IDs sent through non-participating aggregators will be blocked. Please refer to https://sgnic.sg/smsregistry/list-of-participating-aggregators for the list of Participating Aggregators. 
 
5. Participating Aggregators may require additional information from users  – While users may have successfully whitelisted their Sender IDs, they should also ensure that they have completed the registration with their Participating Aggregators. We understand that some of the users failed to provide documents requested by the Participating Aggregators for their due diligence checks and hence their account registration with these Participating Aggregators was not completed. This resulted in the Participating Aggregators disallowing the user from sending SMS at all or converting the SMS sent by these organisations to “Likely-SCAM”. 
 
6. Send a test SMS first – It is good practice for users to test-sending an SMS to ensure that the SMS will be delivered properly, before sending the SMS to the rest of their users. 
 
What is a Letter of Authorisation?
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 LOA template for representative here.
What are the best practices for sending SMS messages?

Security of the SMS account(s) and Sender ID(s) (SIDs) held with your Participating Aggregator(s) (“PAs”)

  1. With the introduction of the Full SMS Sender ID Registry (SSIR) Regime on 31 January 2023, organisations using alpha/alphanumeric/numeric Sender IDs (SIDs) in their SMS messages to Singapore mobile users must first register the SIDs with SGNIC. Participating Aggregators(s) (“PAs”) will check to ensure that SMS bearing registered SIDs are sent from accounts of their registered owners or their authorised representative. However, scammers have been known to exploit vulnerabilities, such as picking on SMS accounts that have not been properly secured by their owners and take over these accounts to send unauthorised SMS. Organisations may suffer reputational damage, financial losses as well as operations disruption to their business from the compromised accounts.
  1. To reinforce the security of your account(s) with the PA(s), please consider the following measures with your PA(s):
  • Updating account credentials and Application Programming Interface (API) keys regularly;
  • Ensuring API key is kept and protected on a secure Key Management System (KMS), managed by a trusted person from your organisation;
  • Removing any decommissioned or unused API keys;
  • Ensuring 2 Factor Authentication (2FA) for admin account access is in place;
  • Checking if your PAs support IP whitelisting, which may help to prevent unauthorized account access; and
  • Exploring with your PAs to set a cap on the number of SMS or issue an alert if SMSes sent exceeded a certain volume per day.
  1. It is strongly encouraged that you take proactive actions to enhance the security of your account(s) and SID(s) to safeguard yourself and your customers.
  1. If you encounter any issues with your SMS delivery, please approach your PAs to ascertain the cause. You may also contact us at [email protected] if you require further assistance.
