Australian SMS Sender ID Register Goes Live July 1, 2026

After several years of consultation and industry preparation, Australia’s SMS Sender ID Register is finally set to go live on 1 July 2026.

This new framework, introduced by the Australian Communications and Media Authority (ACMA), will change how organisations send branded SMS messages to customers across the country. For businesses that rely on SMS to deliver important updates such as delivery notifications and service alerts, understanding the upcoming changes is essential.

What is an SMS Sender ID?

An SMS Sender ID is the alphanumeric name that appears as the sender of a text message, replacing a phone number.

A branded Sender ID is used for transactional messages where replies are not necessary, building trust and brand recognition.

Why has the SMS Sender ID Register been introduced?

The goal of the Sender ID Register is to reduce SMS scams and protect Australian consumers.

Over recent years, scammers have increasingly used SMS messages to impersonate trusted organisations such as banks, government agencies, and delivery companies. These fraudulent messages often appear legitimate because they use spoofed Sender IDs, the brand name that appears at the top of a text message.

By impersonating well-known brands, scammers can trick recipients into clicking malicious links or sharing personal information.

To address this, the Australian Government and ACMA are introducing the Sender ID Register to ensure only verified organisations can use specific branded Sender IDs.

The new system is designed to restore trust in SMS communications and give consumers greater confidence that messages from recognised brands are legitimate.

What is the SMS Sender ID Register?

The SMS Sender ID Register is a national database that verifies which organisations are authorised to use specific SMS Sender IDs.

Under the new rules businesses that send SMS messages using a branded Sender ID must register that Sender ID and authorise partners such as Radaro to utilise the branded Sender ID.

From 1 July 2026, unregistered Sender IDs will be labelled “Unverified”, warning recipients that the sender has not been authenticated. In some cases, these messages may also be filtered or blocked by mobile networks.
