Understanding the SMS Sender ID Register in Australia
If your business sends appointment reminders, invoices, delivery updates, OTPs or promotional SMS using your company name, the new ACMA SMS Sender ID Register may affect how your messages appear to customers.
Businesses using an unregistered branded Sender ID may find their messages displayed as “Unverified”, reducing customer confidence and making legitimate messages easier to ignore.
This guide explains what the SMS Sender ID Register is, who needs to register, what happens if you don’t, and how Broadconnect can help your business complete the registration process and continue sending trusted business SMS.
Key Takeaways
- The ACMA SMS Sender ID Register helps prevent SMS impersonation.
- Businesses using branded Sender IDs may need to register.
- Unregistered Sender IDs may appear as “Unverified.”
- Broadconnect can help businesses complete the registration process.
What Changed on 1 July 2026?
From 1 July 2026, businesses using branded SMS Sender IDs must register them. If a Sender ID isn’t registered, participating mobile networks may replace your business name with “Unverified”, making it harder for customers to recognise and trust your messages. Businesses that rely on appointment reminders, OTPs, invoices, delivery updates or marketing SMS should register their Sender IDs to avoid disruption.
Why the SMS Sender ID Register Matters
SMS has become one of the most effective ways for businesses to communicate with customers. Whether it’s confirming an appointment, sending a verification code or notifying customers about an order, people are far more likely to read a text message than an email.
Unfortunately, scammers have also taken advantage of branded SMS by impersonating well-known organisations. Messages appearing to come from banks, delivery companies or government agencies have been used to trick Australians into sharing personal information or making fraudulent payments.
To help reduce these scams, ACMA introduced the SMS Sender ID Register, allowing legitimate businesses to register their branded Sender IDs and making it easier for customers to recognise genuine business messages.
If your organisation uses its business name as the sender instead of a phone number, understanding these new requirements is essential.

Does Your Business Need to Register?
Not every business will need to register, but many organisations that send branded SMS messages will.
You should consider registering your Sender ID if your business sends SMS using your company name instead of a mobile number.
Common examples include:
- Appointment reminders
- Delivery notifications
- Payment reminders
- One-time passwords (OTPs)
- Customer verification codes
- Marketing campaigns
- Event reminders
- Service updates
- Booking confirmations
This applies across many industries, including:
- Healthcare
- Financial services
- Retail
- Education
- Real estate
- Hospitality
- Trades
- Professional services
- Logistics
- Utilities
If your customers normally see your business name, for example: ABC Plumbing or My Dental Clinic, rather than a mobile number, your Sender ID may need to be registered. You will need a valid Australian drivers license or passport matching the authorised user applying for the Sender ID
If you’re unsure whether the new requirements apply to your business, Broadconnect can help assess your current SMS setup and guide you through the next steps.
⚠ Don’t assume you’re already covered.
Using a branded Sender ID before July 2026 doesn’t automatically mean it’s registered under the new framework.
What Is an SMS Sender ID?
An SMS Sender ID is the name that appears as the sender of a text message instead of a mobile phone number. Rather than receiving a message from a number like 0412 345 678, customers see your business name, making it immediately clear who the message is from.
What Happens If You Don’t Register Your Sender ID?
If your business uses a branded Sender ID but doesn’t register it, your messages may be displayed as “Unverified” on supported mobile networks.
While your SMS may still be delivered, an “Unverified” label can make customers question whether the message is legitimate. In an environment where SMS scams are becoming increasingly common, people are far more cautious about opening links or responding to unexpected messages.
An unregistered Sender ID could lead to:
- Customers ignoring important business messages.
- Reduced trust in your brand.
- Lower engagement with appointment reminders, payment notices and promotional campaigns.
- Increased uncertainty about whether your message is genuine.
For businesses that rely on SMS to communicate with customers, maintaining trust is just as important as ensuring messages are delivered.

The register was introduced to help reduce SMS impersonation scams and improve trust in business messaging. By verifying branded Sender IDs, customers can have greater confidence that messages are coming from legitimate organisations.
3. What happens if I don’t register my Sender ID?
