Singapore | Sending Requirements FAQs

Given the recent changes to requirements for sending messages to Singapore, it’s understandable that you may have some questions.

We recommend you check out the Frequently Asked Questions on the SGNIC’s website for information about the regime, cost, and registration requirements.

Some additional information is summarised below:

Is registration mandatory?

The Sender ID Registry Regime applies to all organisations sending messages with Sender IDs to Singapore numbers from 30 January 2023.  We can’t guarantee the delivery of messages that don’t comply with the registration requirements (including the Letter of Authorisation). Refer to our policy for more information. 

Can CakraFlash! register a SenderID for me?

No. We’re unable to complete this for our customers.

The regulations specify that the customers must apply for their registered Sender ID(s). Once you’ve successfully registered your Sender ID(s), you must provide us with a Letter of Authorisation, email to support@cakraflash.com .

What is a Letter of Authorisation?

An organisation may authorise a representative like CakraFlash! to send an 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 them. To authorise that marketing firm 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.

Email support@cakraflash.com to get the LOA template.

Does this affect international roaming?

The Sender ID Registry Regime applies to all organisations sending messages with Sender IDs to Singapore numbers from 30 January 2023.  After that date, messages containing unregistered Sender ID(s) to Singapore numbers may be blocked.

Which participating aggregator do I need to specify when I register my Sender ID(s)?

You will need to select Sinch Singapore Pte Ltd as the participating aggregator.

What if I want to add more Sender IDs later?

If you decide to register additional Sender IDs, you must send us a revised Letter of Authorisation.  You can email support@cakraflash.com for the LOA letter.

What do I do if I no longer need to send messages to Singapore?

You have two options:

1. Remove Singapore numbers from your contact lists.

2. You can contact our support team to have Singapore sending blocked on your account.

Alternatively, you could do nothing – just remember that if you send any messages to Singapore (deliberately or otherwise), your sender ID will be marked as “Likely-SCAM” as a default for a transitional period of six months. After that, it will be blocked altogether, and your messages will not reach their intended recipients.

What happens if I don’t do anything?

Suppose you haven’t contacted us to block Singapore, and you attempt to send messages with unregistered SenderIDs to Singapore. In that case, your messages may be blocked, and charges may apply under your Customer Contract. Please refer to our policy for more information.
