Registering SMS Sender IDs in Singapore

A few weeks ago, we published a blog post about the process of registering alphanumeric Sender IDs. Today, we’re announcing support for registering Sender IDs in Singapore.

About Sender ID registration in Singapore

Singapore’s Infocomm Media Development Authority (IMDA) has created a Sender ID registry to protect consumers from fraudulent and malicious SMS messages. This registry is called the Singapore SMS Sender ID Registry (SSIR).

The government of Singapore encourages all government agencies and financial institutions to register with SSIR. Organizations and businesses outside of these industries can also register with SSIR.

Currently, there is no requirement to register your Sender ID. However, when you register with the SSIR, your Sender ID becomes a “Protected Sender ID.” Protected Sender IDs help to protect you and your customers by preventing other senders from using your Sender ID.

Note that in order to complete this registration process, your business or organization must have a Unique Entity Number (UEN). Businesses and other organizations receive a UEN when they register with Singapore’s Accounting and Corporate Regulatory Authority.

Registering your Sender ID

The first step in the registration process is to create a case in the AWS Support Center. You can find the procedure for opening a case in the Amazon Pinpoint User Guide. In your case, provide the following information:

  • The AWS Region that you use with Amazon Pinpoint.
  • The name of your company or organization.
  • An estimate of the number of messages that you plan to send through this Sender ID each month.
  • A description of your use case.
  • Information about the steps that your recipients must complete to opt in to receiving your messages.
  • Confirmation that you collect and manage opt-ins and opt-outs.

The AWS Support team will respond to your case within 24 hours. Their response includes a template for a letter that shows your intent to register a Sender ID. The next step is to modify the contents of this letter. The regulatory groups in Singapore require a copy of this letter in order to allow AWS to send messages using your Sender ID. Begin by placing the contents of the letter on your company’s letterhead. Next, modify the fields that are highlighted in yellow. These fields include the following:

  • <Place>: The address of your company or organization.
  • <Brand Owner Company Name>: The name of your company or organization.
  • <Number>: Your Unique Entity Number.
  • <Signature>, <Name>, <Title>: The personal signature, name, and job title of the person who is submitting the request on behalf of your company or organization.
  • <ExampleSenderId1>, <ExampleSenderId2>: The Sender IDs that you intend to register with SGNIC. You can add or remove lines here depending on how many Sender IDs you plan to register.

Once you finish modifying the letter, submit it by attaching it to your existing case in the AWS Support Center.

You will receive a notification through your Support Center case when the Sender ID has been added to your Amazon Pinpoint account. Once you receive this notification, contact the Singapore Network Information Centre (SGNIC) to begin the process of creating your Protected Sender ID. To initiate the registration process, send an email to smsregistry@sgnic.sg. In your message, include the name of your business, the Sender IDs that you want to register, and a description of your use case. SGNIC may contact you for additional information about your use case.

What happens next?

IMDA regularly sends us lists of new Sender ID registrations. When we receive confirmation that your Sender ID has been registered, we update your account to allow it to send SMS messages through your Sender ID. We will also comment on your Support case to indicate that the process is complete.

Wrapping up

We continue to monitor changes to Sender ID registration requirements around the world. We’re working closely with carriers and organizations around the world to make the registration processes as straightforward as possible for our customers. Check in on this blog regularly to learn more about future regulatory changes.
