If your business sends SMS messages using a branded Sender ID, then the clock is officially ticking. In just over a month Australia’s new SMS Sender ID regulations will come into effect, and if your business isn’t prepared you could see your messages flagged as “Unverified” or not delivered at all.
For many businesses, SMS has become one of the most important communication channels available. Appointment reminders, delivery updates, authentication codes, promotions, customer support messages, and urgent notifications all rely on customers instantly recognising who a message is from. That trust is what the Australian Communications and Media Authority (ACMA) is trying to protect with the introduction of the new SMS Sender ID Register.
The problem is that many organisations still haven’t acted to ensure they’re prepared. Is yours one of them?
What are the new Sender ID Laws?
From the 1st of July 2026, organisations that use branded SMS Sender IDs in Australia must have those Sender IDs officially registered.
A Sender ID is the alphanumeric name that appears instead of a phone number at the top of a text message, like “MyGov”, “AusPost”, or your business name. These easily identifiable names help customers recognise legitimate messages, but they’ve also become a target for scammers or other malicious parties impersonating trusted brands.
The new laws are designed to reduce SMS scams by verifying which businesses are authorised to use specific Sender IDs. Under the new system, telecommunication and messaging providers will be required to check and validate businesses before allowing them to continue sending branded SMS messages.
If your Sender ID isn’t registered by the deadline, your messages may no longer appear under your business name. Instead they could be labelled as “Unverified”.
Why your business needs to take the new Sender ID Registration Laws seriously.
A lot of businesses are still treating these changes as something they can “sort out later”, but later is almost here.
Once the laws take effect on the 1st of July, unregistered Sender IDs won’t just lose the branding, they’ll be marked as “Unverified” and are likely to see lower open rates, reduced trust, and far less engagement from customers who are cautious about scam texts.
If you send appointment reminders, two-factor authentication codes, order confirmations, or payment notifications, you can’t afford for your customers to be ignoring them because they look suspicious. It has the potential to completely disrupt your businesses day to day operations.
The ACMA has also made it clear that this is part of a broader national crackdown on fraudulent communications and scams. Australians are becoming increasingly aware of SMS fraud and mobile providers are now playing a much more active role in identifying unverified messages.
If your business fails to act and get your Sender ID verified, you risk damaging the trust you’ve spent years building with your customers.
The deadline is close.
While the official enforcement date is the 1st of July 2026, the ACMA has been recommending that businesses register well before then to avoid delays. With only a month remaining, telecommunication providers are expecting a last-minute rush of businesses trying to register Sender IDs. That means that if you leave things too late you may run into processing delays, verification issues, or temporary interruptions to your messaging services.
This is especially important if your business uses SMS heavily across marketing, customer service, or security communications. If SMS is a core part of your business’s customer journey, now is the time to ensure your Sender IDs are compliant.
What does your business need to do?
Fortunately, the process is relatively straightforward when handled through the right provider. You need to work with your SMS or messaging provider to register your branded Sender IDs. The Sender ID registration process involves verifying your organisation and confirming that your business has a legitimate right to use the Sender ID you’re applying for.
For most businesses this will simply mean reaching out to your provider and having them begin the process as soon as possible.
Good news for legitimate businesses.
While the new regulations could feel frustrating at first, this change is ultimately designed to protect both businesses and customers. Scam messages have become a major problem in Australia, with malicious parties regularly impersonating banks, government departments, delivery companies, and other trusted brands. The Sender ID Register aims to make that much harder by verifying legitimate organisations before they can send branded messages.
For your legitimate business, this means your branded messages will be more trusted. Your customers will have more confidence in your branded messages, which should improve engagement and reduce any confusion or suspicion about fake messages.
