Register your SMS Sender ID with ACMA
Deadline: 1 July 2026. From this date, the Australian Communications and Media Authority (ACMA) requires every SMS sender name delivered to Australian recipients to be on the SMS Sender ID Register. Unregistered sender names will be overstamped as "Unverified" on Australian carriers, which can affect customer trust and message delivery.
This article walks you through registering your SMS sender names through the Atom Telecom portal. Registration is free, takes about 5 minutes per sender name, and you can save drafts and resume any time.
