Singapore SMS Features and Restrictions
Sender ID
Due to 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, organisations can register their alphanumeric 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. 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' for 6 months and will be blocked thereafter (i.e. from 1stAugust 2023 onwards, SMS with non-registered Sender IDs will be blocked and not delivered to mobile subscribers in Singapore). 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.
New regulatory process that is impacting all customers who wish to terminate Singapore traffic via Vonage
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 key notes 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 the Singapore users via SMS should start the registration with SGNIC immediately. 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 SGNIC’s FAQ
-
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 is 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.
- Customers can refer to SGNIC's Sender ID Rules of Registration for further information.
-
Will I be charged for registration with SGNIC?
- Yes, this is charged services. You can refer to the SSIR User Agreement listed in SGNIC's website for the possible costs.
-
What will happen to my existing and new traffic to Singapore with Sender ID that are not registered yet?
- Sender IDs that are not registered are converted to “Likely-SCAM” for 6 months from 31 January 2023. Thereafter, it will be blocked.

-
What do I need to do in order to prepare for registration with SGNIC?
- Before the registration: Customers should directly register with SGNIC and provide all necessary documents as requested by them.
-
After the registration: Once your registration is approved by SGNIC, kindly reach out with your registration details to your Vonage account manager or Support team regarding the whitelisting of the Sender ID with Vonage. If your company is a representative to send SMS with an organisation’s registered Sender ID, you are required to provide us with the Letter of Authorisation (LOA) from the organisation which states that they authorise your company to send SMS with the registered Sender ID on their behalf. You can download the LOA template for representative here.
