Due to increase of spam/smishing SMS in Singapore, the local regulator Infocomm Media Development Authority ("IMDA") has established the Singapore SMS Sender ID Registry (“SSIR”) in March 2022. Under this SSIR Regime, organizations can register their alphanumeric sender IDs directly with the regulator's registry on a voluntary basis 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 will 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. 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 the regulator's registry 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
