From 30 January 2023, messages sent to Singapore numbers using unregistered sender identification (Sender ID) including long codes and short codes, may be blocked.
How to register your Sender IDs
To send messages using Sender IDs to Singapore numbers, you’ll need to register your Sender IDs (including short codes, e.g. 7XXXX and long virtual numbers). This will help strengthen safeguards against scammers.
When it comes to registering your Sender IDs, there are a few steps involved, so we’ve set out a summary below. We recommend you check out the IMDA website for more detailed information about the process.
1. First, you need to have a Singapore unique entity number (UEN) in order to register a Sender ID. Foreign-based businesses can obtain a Singapore UEN by registering with the Accounting and Corporate Regulatory Authority (ACRA).
2. Once you have your Singapore UEN sorted, go to the SSIR portal to register your Sender ID(s). You may need to create an account if you don’t already have one. Please note there is a SGD500 setup fee with SSIR and a SGD200 fee per Sender ID registration. You'll need to select Sinch Singapore Pte Ltd as the participating aggregator.
3. Once you’ve successfully registered your Sender ID(s), you’ll need to provide us with a letter of authorisation (LOA) on your company’s letterhead – please email firstname.lastname@example.org to request a copy, or you can download a copy below.
- Be sure to select the correct letter template for your region:
- For UK, select "MessageMedia UK - Singapore Sender ID - LoA.docx"
- For US and Canada, select "MessageMedia USA Inc - Singapore Sender ID - LoA.docx"
- For AU, NZ and other, select "Message4U Pty Ltd - Singapore Sender ID - LoA.docx"
4. Once you've filled in and signed the letter on your company letterhead you can return it directly to us at email@example.com.
Once you submit the Letter Of Authorisation to us what happens?
1. We'll submit the paperwork to the relevant parties and await confirmation from them of the successful whitelisting of the account.
2. We'll then provision your number.
3. You'll receive confirmation from us that you're approved for sending to Singapore.
If you have any questions about the letter of authorisation, you can contact our support team at firstname.lastname@example.org.
If you have questions about the registration requirements, you'll need to contact email@example.com or visit the Singapore Network Information Centre (SGNIC) website.
