Has Your Business Registered for an SMS Sender ID? Changes Coming 1 July 2026

Its time for businesses to register for Sender ID.

For many small businesses, text messages are an essential part of customer communication. Appointment reminders, delivery notifications, payment updates and marketing campaigns increasingly rely on SMS because of its high open rates and immediate reach.

However, from 1 July 2026, businesses using branded text messaging may face an unexpected challenge if they haven't taken action.

Australia is introducing a new SMS Sender ID Register designed to combat text message scams and make it harder for criminals to impersonate trusted organisations. While the initiative is primarily aimed at protecting consumers, it also creates a new responsibility for businesses that use branded SMS communications.

The change could impact how customers see, trust and respond to your messages.

 

What Is Changing?

 

A sender ID is the name that appears at the top of a text message instead of a phone number. Businesses often use sender IDs such as their company name, practice name or brand name when communicating with customers.

From 1 July, branded sender IDs that have not been registered will no longer display the business name. Instead, customers will see the label "Unverified".

According to the Australian Communications and Media Authority (ACMA), these messages will also be grouped alongside other unverified messages, including potential scam messages.

While that may sound like a small change, the impact on customer engagement could be significant.

Imagine an appointment reminder from your dental clinic, a delivery notification from your online store, or an invoice reminder from your accounting firm arriving under an "Unverified" label. Customers may be less likely to open, trust or act on the message.

 

Why Small Businesses Need to Pay Attention

 

The challenge is that many businesses may not even realise they are using a branded sender ID.

Many modern booking systems, CRM platforms, payment reminder services and marketing tools automatically send messages using a business name rather than a phone number.

According to ACMA Deputy Chair Adam Suckling, some businesses remain unaware that the new rules apply to them.

"Branded sender IDs are widely used by businesses of all shapes and sizes in their marketing, appointment scheduling and billings," Mr Suckling said.

"We are urging small businesses and community organisations to act now, work out if your organisation uses branded sender IDs and contact your telco or message provider if you want to continue using them from 1 July."

The warning is particularly relevant for small businesses that rely heavily on automated customer communications.

 

Who Could Be Affected?

 

The new rules don't just apply to large brands. According to ACMA Deputy Chair Adam Suckling, sender IDs are commonly used by "dentists, GPs, solicitors, schools and childcare centres, and franchisees."

In reality, many local businesses use sender IDs without even realising it. If your business sends appointment reminders, booking confirmations, payment notifications or customer updates through a software platform, there's a good chance a branded sender ID is already being used.

That's why businesses should take notice. If important communications begin appearing as "Unverified", customers may be less likely to trust or engage with them.

As Mr Suckling warned, "Failing to register may mean consumers miss important messages or no longer trust them."

The consequences could include missed appointments, delayed payments, reduced response rates and increased customer support enquiries.

There is also a reputational risk. "Messages labelled 'Unverified' may be ignored or deleted by customers, creating reputational risks and unwanted disruptions for businesses," Mr Suckling said.

At a time when Australians are more cautious than ever about scams, maintaining trust in customer communications is essential.

The changes are part of a broader effort to tackle the growing problem of SMS scams across Australia. Over time, the register should improve confidence in SMS communications and make it easier for businesses to distinguish themselves from bad actors.

 

What Business Owners Should Do Now

 

The good news is that most businesses can resolve the issue relatively quickly.

Start by reviewing recent text messages sent to customers. If a business name appears instead of a phone number, contact your SMS provider, software platform, telecommunications provider or CRM provider and ask whether your sender ID has been registered.

You should also ensure your Australian Business Register (ABR) details are current and accurate, as this may be required during the registration process.

Businesses can learn more through the ACMA's official SMS Sender ID Register and registration guidance.

For many businesses, this will be a simple administrative task. However, the consequences of ignoring it could be far greater than expected.

Customer trust is one of the most valuable assets a business owns. As SMS scams continue to rise, consumers are becoming increasingly selective about which messages they trust.

Taking a few minutes now to confirm your sender ID registration could help ensure your business remains recognisable, credible and connected with customers after 1 July.

 

What This Means if You're Buying or Selling a Business

 

Changes like the SMS Sender ID Register are also a reminder that business systems and customer communication processes form part of a business's value.

If you're selling a business, ensuring your sender IDs are properly registered demonstrates that your systems are compliant, your customer communications are functioning correctly, and there are no unnecessary risks for a buyer to inherit.

For buyers, it's another item worth adding to your https://bsale.com.au/article-display/what-is-due-diligence-in-a-business-sale,1241due diligence checklist. Understanding how a business communicates with customers, what software platforms are being used, and whether critical systems are properly configured can help avoid unexpected disruptions after settlement.

A business may have a strong customer database and automated communication systems, but if appointment reminders, payment notifications or customer updates suddenly begin appearing as "Unverified", it could impact customer engagement and trust.

As technology and compliance requirements continue to evolve, maintaining well-managed business systems is becoming an increasingly important part of protecting both business value and customer relationships.
