TLDR: What Actually Changed

• From 1 July 2026, any business texting customers under a brand name (not a random number) must register that name on the SMS Sender ID Register.
• Not registered? Your texts now show as ‘Unverified’ right in the message thread on your customer’s phone.
• This sits under the wider Scams Prevention Framework, which carries fines of up to $50 million for banks, telcos and big digital platforms who don’t play their part.
• The fix for most small businesses is simple: ask your telco or SMS platform to register your sender ID. It usually takes a few business days.
• Every day you wait, your appointment reminders, order updates and promo texts are showing up looking like a scam warning, through no fault of your actual message.

Key Stats

• 60%+ drop in SMS scam reports since 2022
• 41 million scam texts blocked by telcos last quarter alone
• $50 million maximum fine per offence under the framework

What Actually Changed on 1 July

Australia’s Scams Prevention Framework passed in February 2025.

It’s a big piece of law that forces banks, telcos and large digital platforms to actively prevent, detect and report scams, with fines up to $50 million per offence if they don’t.

The part that affects your business is one small, practical piece of that framework: the SMS Sender ID Register.

It’s simple in concept. If your business sends texts under a brand name, think “AusPost” or “MyClinic” instead of a random mobile number, that name now has to be registered.

If it isn’t registered, your customer’s phone stamps the message as ‘Unverified’ right inside the text thread. Same message, same offer, same tone. Just a label sitting next to it that makes people pause.

Think of it like this A tradie turning up in a van with the business name and logo on the side gets a different reaction than the same tradie turning up in a plain white van. Both might be doing a perfectly good job. But one gets you opening the door straight away, and the other gets a second look first. That second look is exactly what ‘Unverified’ now does to your texts.

So What Does This Actually Mean for Your SMS Marketing

Here’s the bit that matters if you’re not a bank or a telco: this isn’t really about big compliance policies for most small and mid-sized businesses. It’s about one thing. Your sender name, and whether it’s registered.

If you send appointment reminders, order updates or promo texts under your business name, that name needs to sit on the register. If it doesn’t, three things happen straight away:

• Open rates take a hit. People are trained to be wary of anything that looks unverified. That hesitation costs you clicks and bookings, even though your message did nothing wrong.
• Trust takes a hit. Customers who see ‘Unverified’ next to your business name might assume the worst, especially the first time it happens.
• It’s easy to miss if you use more than one tool. If your CRM, your booking platform and your marketing tool all send SMS separately, each one needs its own sender ID registered. Missing just one still shows ‘Unverified’ to those customers.

The good news is this is a quick fix once you know it needs doing.

It’s not a redesign of your marketing. It’s a five-minute conversation with your telco or SMS provider to get your name added to the list.

What Your Customers Are Now Seeing

Any text sent under an unregistered brand name now carries an ‘Unverified’ tag in the thread. Registered senders, banks, MyGov, the bigger delivery companies, look exactly as they always have.

Zooming out, this is genuinely good news for everyone. SMS scam reports are down more than 60% and total scam losses have dropped close to 30% since 2022, largely because telcos have been blocking scam traffic ahead of this rollout. Last quarter alone, telcos blocked 41 million scam texts before they even reached a phone.

But it’s worth remembering: ‘Unverified’ isn’t proof of a scam. Most of the time it just means a legitimate small business hasn’t registered yet. If that’s you, the label is doing more harm to your business than any scammer ever did.

Your Action Checklist for This Week

• Check your sender ID status. Ask your telco or whichever platform sends your reminders, promos or order updates whether your business name is registered.
• Register straight away if you’re not already. Most telcos and SMS platforms can do this directly, usually within a few business days. Every day you wait, customers are seeing ‘Unverified’.
• Audit every tool that sends texts on your behalf. CRM, booking system, marketing platform. Each one needs its own sender ID checked separately.
• Check if the wider framework applies to you. If you operate in banking, telecommunications, or offer digital advertising or messaging services, you may need documented scam-prevention policies and a clear complaint process.
• Watch for the finalised sector rules. Consultation on detailed obligations closed 25 June 2026, with more specific requirements expected over coming months. Keep an eye on updates from ACMA and Treasury.
• Review your message content anyway. Even with a verified sender ID, steer clear of urgent payment requests or unusual links. That’s exactly what scam filters and cautious customers are trained to flag.

How Your Customers Can Protect Themselves

• Treat ‘Unverified’ as a pause signal, not a verdict. It often just means a legitimate business hasn’t registered yet.
• Verify independently. Go to the official app or website directly. Never tap a link inside a text to confirm anything.
• Watch for the real red flags. Unexpected payment requests, one-time codes you didn’t ask for, and urgent account warnings are the biggest tells.
• Act fast if something looks wrong. Contact your bank straight away to freeze suspicious activity, then your telco to check your account.
• Report it. File with Scamwatch, and if identity theft is a risk, contact IDCARE for help.

Worth knowing too: the government has proposed automatic reimbursement for verified losses under $3,000 where a business failed to have proper scam controls in place. It’s not law yet, but it shows the direction things are heading.

The Bottom Line

This is one of those rare cases where doing the compliant thing and protecting your bottom line are the same action. An unregistered sender ID is now visibly costing you trust every single time you hit send.

If you send branded SMS and haven’t checked your registration status, that’s this week’s job. And if you’re passing this on to your own customers, the message is simple: ‘Unverified’ means slow down and check independently, not panic.

Quick Answers (FAQ)

What is the SMS Sender ID Register?

A national register, live from 1 July 2026, where businesses record the brand name they use to send SMS. Unregistered names now show as ‘Unverified’ on the recipient’s phone.

What happens if I don’t register my sender ID?

Your texts show an ‘Unverified’ label in the customer’s message thread, which tends to lower open rates and trust, even if your message content is completely legitimate.

How do I register my business name?

Contact your telco or SMS marketing platform directly. Most can register your sender ID for you, usually within a few business days.

Does this apply to small businesses?

Yes. Any business sending branded SMS, regardless of size, needs its sender name registered. The heavier compliance obligations under the wider framework mostly apply to banks, telcos and large platforms.

Is ‘Unverified’ proof that a text is a scam?

No. It usually just means a legitimate business hasn’t registered its sender ID yet. Treat it as a reason to verify independently, not automatic proof of a scam.

What is the Scams Prevention Framework?

A law passed in February 2025 that requires banks, telcos and big digital platforms to actively prevent, detect and report scams, backed by fines up to $50 million per offence. The Sender ID Register is one practical piece of it.
