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 ID(s).
To send messages using Sender IDs to Singapore numbers, you’ll need to register your Sender ID(s) (including short codes, e.g. 7XXXX and long virtual numbers). This will help strengthen safeguards against scammers.
When it comes to registering your Sender ID(s), 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.
- 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).
- 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.
- 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 email@example.com to request a copy, or you can download a copy below.
- Once you've filled in and signed the letter on your company letterhead you can return it directly to us at firstname.lastname@example.org
Once you submit the Letter Of Authorisation to us what happens?
- We'll submit the paperwork to the relevant parties and await confirmation from them of successful whitelisting of the account.
- We'll then provision your number.
- You'll receive confirmation from us that you're approved for sending into Singapore.
If you have any questions about the letter of authorisation, you can contact our support team on email@example.com.
If you have questions about the registration requirements, you'll need to contact firstname.lastname@example.org or visit the Singapore Network Information Centre (SGNIC) website.
