Your phone is about to get a little smarter at spotting scams – but the changes could also mean some legitimate messages get caught in the crossfire.
From medical appointment reminders and school updates to bills and important account alerts, millions of Australians rely on branded text messages every day. But from Wednesday 1 July, new anti-scam rules mean businesses that haven’t registered their branded SMS sender IDs could see their messages labelled as “Unverified” and pushed into the same thread as suspicious spam.
In other words, that important reminder you’ve been waiting for could look a lot like the scam texts you usually delete.
The change is part of a wider crackdown on scam messages, designed to stop criminals impersonating trusted organisations. Scam texts pretending to be from banks, delivery companies and government services have become increasingly sophisticated, making it harder for Australians to know what is real and what is fake.
Branded SMS sender IDs are the names that appear at the top of a text message – think names like AusPost, Med-Appt or myGov – helping customers instantly recognise who a message is from without needing to rely on an unknown phone number.
But according to the Australian Communications and Media Authority (ACMA), only around 20 per cent of Australian businesses and organisations have registered for the new scheme so far. This has raised concerns that a large number of genuine messages could soon be treated with the same suspicion as scam texts.
Vodafone is warning the impact could be immediate, with Australians potentially missing everything from healthcare reminders to school communications if businesses don’t complete the registration process.
“Australians could start missing critical messages like medical reminders and school alerts from 1 July if businesses don’t act now,” a Vodafone spokesperson said.
“Australians rely on text messages every day for important updates whether it’s a medical appointment, a bill or a school alert and those messages could stop getting through if businesses don’t register their sender IDs.”
The spokesperson added that from July 1, the system will be more likely to flag unregistered texts as unverified, meaning customers may ignore, delete or distrust these messages.
“We’re urging businesses to register as soon as possible so Australians don’t miss the messages they rely on.”
Why this matters in the age of digital trust
While most people think of cybersecurity as something involving passwords, apps and online accounts, the humble text message has become one of the biggest battlegrounds in the fight against scams.
SMS remains one of the quickest ways for organisations to reach customers because it is immediate, familiar and doesn’t require people to open an app or check an email inbox.
But that convenience has also made it a favourite tool for scammers.
Fake delivery updates, banking alerts and government impersonations have trained Australians to be cautious about unexpected messages – which means businesses now need to prove their identity more clearly than ever.
The new sender ID rules aim to create a safer digital environment by making it easier to separate trusted brands from potential scams.
How businesses can register before the changes
Businesses that send branded SMS messages need to make sure their details are up to date and complete the registration process through their sender ID provider.
To start, businesses should first check that they have current information listed on the Australian Business Register (ABR), which verifies their identity for the registration process.
Businesses can update their details by visiting abr.gov.au, selecting “Update your ABN details” and logging in using their Digital ID linked to their ABN.
They should also check their authorised contacts, including the “authorised contact” or “service of notice” email addresses, to ensure the right people can approve the registration.
After updating and submitting their ABR details, businesses must contact their sender ID provider to complete the final registration step. When the telco submits the application, an authorised contact listed on the ABR will need to confirm the request via email.
For Australians, the takeaway is simple: if a familiar business text suddenly looks different after July 1, it may not mean it’s fake – it could simply be a business that hasn’t completed its registration.
As scammers become smarter, we must build greater trust in digital communication and ensure important messages stand out from the ones we don’t need.
