SMS Sender ID Registration Australia
The SMS Sender ID Register is an Australian Communications and Media Authority initiative designed to reduce scams and improve trust in business messaging.
What You Need to Know Before 1 July 2026
If your business sends SMS messages using a branded sender name, new regulations mean you must register your Sender ID to avoid disruptions.
From 1 July 2026, unregistered Sender IDs may be marked as Unverified, which can reduce trust, impact deliverability and affect how your customers respond to your messages.
Media Booth® can help you understand whether this applies to your business, identify which Sender IDs need to be registered and support you through the registration process.

What Is a Sender ID?
A Sender ID is the name or number that appears when your business sends an SMS. Instead of a mobile number, your message might display your business name.

Used by medical clinics, salons and service providers to confirm bookings, reduce missed appointments and keep schedules running smoothly.

Avoid Message DisruptionWhat Is Changing?
ACMA is introducing a mandatory Sender ID Register to reduce scams and improve trust in SMS communications. From 1 July 2026, unregistered Sender IDs may be labelled as Unverified.
Unregistered Sender IDs May Be Marked Unverified
From 1 July 2026, unregistered Sender IDs may be labelled as Unverified. This can make business messages look less trustworthy to customers. If your business relies on branded SMS messages for marketing, alerts, reminders or customer updates, registration should be reviewed before the deadline.
Preparing early gives your business time to confirm which Sender IDs need to be registered and avoid possible disruption.
Registered Sender IDs Support Legitimate Messaging
Registered Sender IDs help customers identify legitimate messages from your business and reduce confusion around suspicious SMS activity. For businesses that use SMS for important updates, registration can help protect customer trust and make branded communication clearer.
Registration also helps reduce the risk of brand impersonation through SMS messaging.
Unverified Messages Can Reduce Customer Trust
If customers see a message marked as Unverified, they may be less likely to trust it, click links or respond. This can affect SMS marketing performance, appointment communication, customer alerts and other business messaging.
Registering your Sender ID can help your business maintain clearer, more trusted communication with customers.
Prepare Your Business Details Before Registering
To register successfully, your ABN details should be current and your Authorised Contact details on the Australian Business Register should be up to date. Outdated ABR details can delay an application, so it is worth checking your business information before registration.
Media Booth® can help guide you through what needs to be checked before submitting a Sender ID registration.
Important Sender ID Registration Deadline
We recommend completing registration by mid May 2026 to allow time for approval and avoid disruption before the 1 July 2026 change. Leaving registration too late may create delays, especially if your business details need to be updated before submission.
Getting started early gives your business a smoother path to compliance.
