This country has mandatory registration, and senders can be used only by clients who registered the sender and provided all documentation for approval. We can not register the sender ID on behalf of the client. Client has to register directly on the SSIR portal by following the steps on this page: https://sgnic.sg/faq/sms-sender-id-registry Once the registration is completed, and SSIR letter of confirmation has been sent to the Client. Client has to submit a letter and ACRA document for internal sender approval. Unregistered sender ID can be approved from our side and if client accepts manipulation of the sender ID to generic sender Likely-SCAM.

Sending to Singapore, answered

Common questions about sender registration, two-way replies, and compliance when launching SMS in Singapore.

Do I need to register a sender before sending SMS to Singapore?

Registration is required for a short code and a long code. Registration is optional for an alphanumeric sender ID. You can send before approval, but the sender ID is overwritten until approval and preserved afterward. Work with Bird on short-code assignment, registration and costs. Short codes are country-specific. For an alphanumeric sender ID the name itself is registered. Confirm how the approved sender is presented on the destination networks. A phone number is registered for this country before it can send business messages.

Can I use an alphanumeric sender ID in Singapore?

Yes. Registration is optional: before approval the carrier overwrites the sender ID, and after approval the approved sender ID is preserved.

How long does sender registration take in Singapore?

The recorded estimate for a short code is about 84 business days; confirm timing before launch.

Can I receive replies from Singapore?

Yes, if you send from a short code or a long code. Replies are delivered to you as signed webhooks.
