The SMS Sender ID Register is now live. As of 1 July 2026, if you send SMS to Australian numbers using a branded Sender ID, that Sender ID needs to be registered with ACMA. If it isn’t, the message can be relabelled “Unverified” on the recipient’s phone and grouped in with the other unverified messages… including scams.
That’s the outcome we want to help you avoid. So here’s what Enfonica does differently.
What “Unverified” actually means
The Register was created to make it harder for scammers to impersonate real businesses over SMS. From 1 July, the Australian mobile networks can overstamp any unregistered branded Sender ID with the word “Unverified” before it reaches the recipient.
The message still sends. It still costs you. But your carefully chosen brand name is gone, replaced by a label that tells people not to trust it, and it may land in the same bucket as suspected scam messages. For a message you actually wanted read, that’s about the worst result possible.
We stop the message before that happens
Rather than let your messages go out stamped “Unverified”, Enfonica simply won’t send them.
If you try to send from an alphanumeric Sender ID to an Australian mobile, and that Sender ID isn’t registered to the Enfonica project you’re sending from, we block the message on our end. You’ll know straight away, instead of finding out after the fact when your campaign has already gone out looking untrustworthy.
We made this call deliberately, for two reasons:
- It keeps you on the right side of the rules. Blocking unregistered branded messages is the safest, cleanest way to stay compliant with ACMA’s requirements: no grey areas and no relabelled messages slipping through.
- It protects your spend. Imagine sending a batch of 50,000 messages, only to have every one arrive as “Unverified” and quietly ignored. That’s a bill for messages nobody trusted or read. We’d rather stop that batch at the door than let you pay for it.
Think of it as a safety net. If a Sender ID isn’t ready, we hold the message so you can fix it, not send it in a state that damages your brand and wastes your money.
This only affects branded Sender IDs to Australian numbers
If you send from a standard phone number, nothing changes. The block only kicks in for alphanumeric (branded) Sender IDs going to Australian mobiles that aren’t registered to your project.
Registering is quick in the Console
The fix is simple: register your Sender IDs before you send. We’ve built the whole process into the Enfonica Console.
- Open your project and go to Cloud SMS → Sender IDs.
- Click Register Sender ID.
- Tell us how the Sender ID links to your organisation (business name, company name, trademark or domain).
- Nominate an authorised representative to confirm the registration with ACMA.
- Submit, and track the status right there in the Console.
There’s a government identity step on ACMA’s side too (involving myID and your ABR details), so it pays to start early. Our full Sender ID Register guide walks through every step.
Get your Sender IDs registered
The Register is live, and unregistered branded messages to Australian numbers aren’t getting through Enfonica. If your Sender IDs are already registered, you’re set. If not, now’s the time.
