How to Externally Register Your Number for Sending SMS Traffic to Singapore

In this article, Cloudtalk would like to inform you about the mandatory registration of Sender IDs (phone numbers) for sending SMS traffic to Singapore mobile numbers.

This initiative was introduced by Singapore regulatory agencies, driven by the surge of pervasive SMS-based phishing and impersonation scams on Singapore mobile networks, and is not able to be influenced by CloudTalk.

To address this concern, the Infocomm Media Development Authority (IMDA) established the Singapore SMS Sender ID Registry (SSIR), acting as a central body for Sender ID registration in Singapore, which is managed by the Singapore Network Information Centre (SGNIC), a subsidiary of the IMDA.

To combat scam SMS traffic effectively, the IMDA requires all organisations sending SMS traffic to Singapore mobile users to register their Sender IDs with the SSIR. As of August 1st, 2023, aggregators and local suppliers in Singapore will start blocking outgoing SMS traffic that does not meet this requirement.

Important Note: CloudTalk cannot perform the registration on your behalf; users must undertake this process themselves. To assist you, we created this step-by-step guide on how to complete the registration.

How to register?

1. Setting Up Your SSIR Portal Account

Before you begin the registration process, it is important to have the necessary information at hand. You do not need to be based in Singapore, but you will need to register your business in Singapore with the Accounting and Corporate Regulatory Authority (ACRA).

  • Ensure you have the company's legal registered name (as per ACRA records), along with its registered address and Unique Entity Number (UEN) issued by the relevant Singaporean government authorities.

    • If your business is based outside Singapore, you can obtain a UEN by registering with the Accounting and Corporate Regulatory Authority (ACRA) as either a local subsidiary or a foreign branch office.

  • You will need to set up a login using the government system CorpPass for the purpose of verification. In the event that you or your customers do not possess a CorpPass, the SSIR may request utility bills or telecom bills as an alternative means of verification.

  • Provide the full name, contact number, and email address of the designated Admin account holder for your company within the portal. This individual will have the necessary privileges to create additional User accounts for your organisation.

2. List Participating SMS Aggregators

During the registration process, you'll be required to submit information regarding the SMS operator (aggregator) who will be delivering your SMS messages.

If you are undertaking this registration, CloudTalk will be able to provide you with this information, based on our subcarriers from which we source the number(s) on your account.

3. List the Sender IDs (phone numbers) to be Reserved for the Company

After creating your account and providing the necessary information, proceed to list the Sender IDs (phone numbers) that you wish to reserve for your company.

4. Complete the Process

Once you have listed the Sender IDs (phone numbers) and provided the required information, proceed to complete the registration process. Review all the details for accuracy and submit your application to the SSIR for verification.

Additional Proof of Assignment

During the registration process, you may be asked to provide additional proofs of assignment for your Sender IDs. In case SGNIC requests further information, CloudTalk can assist you with obtaining the required documentation from our subcarrier/aggregator to support your application. Please, contact us at [email protected]

Fees and Charges

The fees associated with the Sender ID registration, which are set by the regulatory authorities, are not able to be influenced by CloudTalk.

There will be a one-time setup fee of S$500 for each organisation applying for Sender ID registration and an annual charge of S$200 per registered Sender ID(phone number).

You will need to pay this directly to SGNIC account, as it is not possible for CloudTalk to register and pay this on your behalf.
