More about Sender ID registration
What else do I need to know?
Necessary registration information has already been provided to you here. In this section, we include commonly-asked questions by agencies that have onboarded onto Postman and gone through the Sender ID registration process themselves. We hope this will be useful to you!
Yes - this is a mandatory initiative by SGNIC/IMDA. If you do not register, any SMS that you send to a Singapore number will be reflected as
Likely-SCAM,regardless of where the recipient is in the world.This also means that your recipients may not trust your SMS content. IMDA also has eventual plans to block all SMSes with unregistered Sender IDs - this means that your messages will not reach your recipients at all.
We understand that one-off campaigns means that you may be registering a Sender ID that will only be used once, which may not justify the costs. In such situations, we generally advise agencies to check internally to see if already-registered Sender IDs can be "borrowed" to be used for this campaign.
No - regardless of whether you use Postman, you will still need to register for a Sender ID as long as you are intending to send SMSes on behalf of your agency. This is a nationwide policy mandated by IMDA.
