Country Summary
Sender ID Guidelines
Due to the increase of spam/smishing SMS in Singapore, the local regulator Infocomm Media Development Authority ("IMDA") has established the Full SMS Sender ID Registry Regime (“Full SSIR Regime”) in March 2022. Under this SSIR Regime, organizations can register their Sender IDs directly with the regulator's registry to protect their Sender IDs. Also, any SMS aggregators who wish to terminate the registered Sender ID traffic to Singapore must be licensed by IMDA. All Sender IDs are subject to regulatory approval. Vonage is happy to announce that we are the licensed SMS aggregator (NEXMO Pte Ltd) with the regulator.
With effect from 31 January 2023, Sender ID registration with the regulator has become mandatory. Only SMS Sender IDs that have been registered with the regulator's registry will be allowed to Singapore. Non-registered Sender ID is converted to a generic Sender ID 'Likely-SCAM' until further notice. You can find more information on SGNIC (IMDA's SMS registry provider) website: https://www.sgnic.sg/smsregistry/overview.
To avoid traffic failure, customers should register their Sender IDs directly with SGNIC as soon as possible. Please take note that the Sender ID is case-sensitive. Once the Sender ID has been successfully registered, kindly reach out to your Vonage account manager or Vonage support regarding the whitelisting of the Sender ID with Vonage.
Important update regarding non-registered Sender ID traffic:
Please note that the original 6-month transition period from 31 January 2023 has now been extended past 1stAugust 2023. All non-registered Sender IDs will be marked as “Likely-SCAM” and will continue to be allowed until further notice from IMDA.
FAQ:
In order to comply with IMDA's requirement, Vonage has made several internal changes to help customers start transiting to and complete the registration. Following are the keynotes and Q&A to go through before you send your new and existing Singapore traffic via Vonage.
-
When should I start the registration with SGNIC (IMDA's SMS registry provider) for my Singapore traffic?
-
Local or Overseas customers with a valid UEN (Singapore Business registration number) who wish to reach out to Singapore users via SMS should start the registration with SGNIC immediately. For more information, please refer to SGNIC’s FAQ.
-
If you don’t have a valid UEN number, you can obtain one by registering with the Accounting and Corporate Regulatory Authority (“ACRA”). For more information, please refer to the how-to-guides on ACRA website for local and overseas companies.
-
What types of Sender IDs will be accepted by SGNIC?
- Each Sender ID must be within 3 to 11 characters (including spaces, underscores or hyphens), cannot contain Chinese or Cyrillic characters, and should not be generic in nature (e.g 'SMS' is generic and not allowed).
- Shortcode and Long virtual numbers (“LVNs”) can possibly be registered as well if the conditions set by SGNIC are met. This means customers who have subscribed Singapore Shortcode or LVN from Vonage must register the number before they can use the number to terminate SMS to Singapore.

Will I be charged for registration with SGNIC?

If your company is a representative to send SMS with an organization’s registered Sender ID, you are required to provide us with the Letter of Authorisation (LOA) from the organization which states that they authorize your company to send SMS with the registered Sender ID on their behalf. You can download the LOA template for the representative here.
