If your association sends branded text messages to members, subscribers, event attendees or stakeholders, a significant change to how SMS works in Australia is on the way, and the deadline is closer than you think.
The Australian Communications and Media Authority (ACMA) is introducing a new SMS Sender ID Register as part of the Federal Government's Fighting Scams initiative. From 1 July 2026, unregistered branded sender IDs will be flagged as "Unverified" — potentially damaging your association's credibility and the effectiveness of your member communications overnight.
Here's what your association needs to know, and what you should be doing right now.
What Is a Sender ID?
A sender ID is the name that appears at the top of an SMS or MMS message instead of a mobile phone number. Think of the text messages you receive from myGov, AusPost or Medicare — the organisation's name appears as the sender, not a number.
For associations, sender IDs might include your:
- Association name or acronym (e.g. "AuSAE", "AHPRA")
- Member communications platform brand
- Event or conference name
- Affiliated franchise or network name
These branded sender IDs help your members immediately recognise that a message is legitimate and from you, rather than a random number they don't recognise.
Why Is This Changing?
Scammers have increasingly exploited branded SMS by impersonating trusted organisations. The Australian Government is tackling this through a range of anti-scam measures, and the SMS Sender ID Register is a key part of that effort.
The register is designed to:
- Verify that branded sender IDs belong to legitimate organisations
- Prevent bad actors from impersonating businesses, government agencies and associations
- Help Australians trust the SMS messages they receive
- Create a safer communications environment across the board
What Happens If Your Association Doesn't Register?
From 1 July 2026, any branded sender ID that hasn't been registered will be automatically labelled as "Unverified" on recipients' devices.
ACMA's own mock-ups show unverified messages being grouped together in a separate "Unverified" thread, much like how spam email lands in a junk folder. For your members, this could mean:
- Your event reminders look like scams
- Membership renewal notices go unread
- Advocacy updates are dismissed
- Time-sensitive communications are ignored
- Your association's credibility takes an unnecessary hit
For associations that rely on SMS to keep members informed, mobilised and engaged, the consequences of failing to register could be significant.
Who Needs to Register?
The changes apply broadly to any Australian organisation using branded SMS communications, including:
- Peak bodies and industry associations
- Professional membership organisations
- Not-for-profits and charities
- Community organisations
- Educational institutions
- Government agencies
If your association — or any platform you use to communicate with members — sends SMS messages with your organisation's name as the sender, you will need to register.
How SMS Is Typically Used by Associations
Associations rely on SMS communications for a wide range of member touchpoints, including:
- Event and conference reminders — dates, times, venue changes, last-minute updates
- Membership renewal notices — prompts and payment reminders
- Advocacy alerts — urgent calls to action for members
- Professional development reminders — webinars, CPD deadlines, course bookings
- Annual general meeting notifications
- Surveys and feedback requests
- Emergency or urgent sector updates
- Login and security verification codes (two-factor authentication)
All of these could be affected if your sender ID is not registered before the deadline.
How to Register
To register a sender ID if you have an Australian Business Number (ABN), your authorised contact or service of notice email address in the Australian Business Register (ABR) must be up to date. Find out more.
Registration is open and the deadline is 1 July 2026.
To register a sender ID, your association will need to:
- Contact your telecommunications or SMS platform provider — this includes your CRM, member management system, or any third-party platform that sends SMS on your behalf. Check your telco is on the list of approved telcos and message providers.
- Provide them with the sender ID(s) you wish to register through that provider. Your provider will register them on your behalf. You will need to demonstrate a valid use case for each sender ID. Find out the types of sender ID you can register.
- Ensure your Australian Business Register (ABR) details match your intended sender ID
- Confirm your registration. You will need to pass checks to verify your organisation, your identity and your authority to act on behalf of your organisation. Your telco or message provider will ask the ACMA to conduct the checks and notify you using the email you provided to your telco.
If you use multiple messaging platforms or providers, you may need to register separately with each one.
Check Your ABR Details Now
The Sender ID Register verification process relies on your Australian Business Register (ABR) information. If your ABN details, trading names, or contact information are outdated, your registration may be delayed or declined.
Before you begin the registration process, check and update:
- ABN registration details
- Trading and registered names
- Contact information
You can update your details at abr.gov.au.
Don't leave this until mid-2026. Provider demand and processing times are expected to increase significantly as the deadline approaches.
Where to Find More Information
For associations, member trust is everything. Your members rely on you to communicate reliably, professionally and credibly, and your SMS communications play an important role in that relationship.
Registering your sender IDs before 1 July 2026 is a straightforward step that protects your association's reputation, ensures your messages continue to reach members as intended, and demonstrates that your organisation is operating at the forefront of safe, professional communications practice.
