From today, Australians should begin to notice a subtle but important change to the text messages they receive from legitimate businesses.

The Australian Communications and Media Authority (ACMA) has officially launched the SMS Sender ID Register, a new initiative designed to make it easier for consumers to identify authentic business messages while making life significantly harder for scammers.

It’s not a silver bullet, but it is one of the more practical measures we’ve seen introduced in Australia’s ongoing fight against SMS-based fraud.

Why this matters

SMS remains one of the most effective ways for organisations to communicate with customers. Banks send security codes, couriers provide delivery updates, healthcare providers confirm appointments, and government agencies issue important notifications.

Unfortunately, scammers know this too.

Over the past few years, Australians have become accustomed to receiving convincing text messages that appear to come from trusted organisations. These phishing attempts often impersonate banks, parcel delivery companies, toll operators and government departments, attempting to trick recipients into clicking malicious links or handing over personal information.

The result has been a gradual erosion of trust in one of the simplest communication channels available.

With the new Sender ID Register, businesses that have registered their SMS Sender ID can send verified messages, providing customers with greater confidence that the message genuinely originated from the organisation it claims to represent. Businesses that have not registered will have their messages delivered as unverified.

While consumers will still need to remain vigilant, adding a layer of verification helps restore confidence in legitimate communications.

Trust has become a security feature

Cybersecurity is no longer just about firewalls and antivirus software. Increasingly, it’s about helping ordinary people make informed decisions in the few seconds between receiving a message and deciding whether to trust it.

Verification mechanisms such as the Sender ID Register help shift some of that burden away from consumers by making authenticity more visible.

According to Hugh Haley, Senior Director, Partners & Carriers APAC at Sinch:

“In 2025 alone, text message scams cost nearly $18 million and most Aussies will have experienced the moment of hesitation when they receive a text claiming to be from their bank, a delivery company or a government agency.”

He added that scams don’t simply steal money.

“By using trusted brand names to exploit everyday people, scammers don’t just take people’s money, they erode the confidence that government organisations and businesses have worked hard to build up with their customers.”

That loss of confidence affects everyone. When consumers begin questioning every appointment reminder, parcel notification or banking alert, legitimate organisations also pay the price.

Not a complete solution

It’s important to remember that no single technology will eliminate scams.

Consumers should continue to:

  • Never click links in unexpected text messages.
  • Verify requests for personal or financial information independently.
  • Contact organisations directly using official phone numbers or websites if something doesn’t feel right.
  • Keep devices updated with the latest security patches.

Likewise, businesses should see Sender ID registration as one component of a broader customer security strategy rather than the final destination.

Our View

The ACMA Sender ID Register is a sensible and long overdue step towards rebuilding confidence in SMS communications.

Scammers are constantly evolving, and the industry needs multiple layers of protection working together. Verified Sender IDs won’t stop every phishing attempt, but raising the bar makes impersonation more difficult and gives consumers another useful signal when deciding whether to trust a message.

The effectiveness of the register will ultimately depend on widespread adoption by businesses and continued cooperation between regulators, telecommunications providers and messaging platforms.

If the initiative succeeds in reducing even a fraction of SMS-based scams while restoring confidence in legitimate business communications, it will be a worthwhile investment in Australia’s broader cyber resilience.

As digital scams become increasingly sophisticated, trust itself has become one of our most valuable security tools.
