Singapore Sender ID registration
Incident Report for Telesign system status
Country: Singapore

Operator: all

Effective date: 31st of October 2022; Deadline: 31st of January 2023

Details: IMDA (Infocomm Media Development Authority) announced that all organizations that wish to send SMS messages with alphanumeric Sender IDs in Singapore must register their Sender IDs with the SSIR (SMS Sender ID Registry). Only registered Sender IDs will reach Singapore users, with effect from 31 January 2023. The companies can start with the registration from the 31st of October, and the 31st of January is the deadline for all Sender IDs to be registered. From the 31st of January, there will be a six-month transition period where all non-registered SMS Sender IDs will be masked to a Sender ID with the header “Likely-SCAM”. This is akin to a “spam filter and spam bin”. Consumers are advised to exercise caution upon receiving such SMS, as these are non-registered Sender IDs. After 6 months, this Sender ID will be closed and all SMS with Sender IDs that are still not registered by then will be blocked.
The organizations that want to register Sender IDs will register them directly with SSIR. Interested organizations can contact the Singapore Network Information Centre ("SGNIC”) at to start the registration process. Registration opens on 31 October 2022.
