What is a “sender ID”?
A sender ID is the name that shows at the top of a text message, like “MyBank“, “MATE“, or “AusPost“, instead of a mobile number. It helps you quickly identify who’s messaging you. It’s not a phone number, it’s a name tag for the sender.
Why is there a new register?
From 1 July 2026, the Australian Communications and Media Authority (ACMA) is launching a new SMS/MMS Sender ID Register to help protect Australians from scam texts.
Here’s how it works:
- Only verified sender names will appear as normal.
- Messages from unregistered sender names will show as “Unverified“, so you know to be cautious.
This aims to reduce scam messages pretending to be from trusted brands like banks, telcos or government services.
What does this mean for you?
Not much – here’s what to expect:
- Messages from registered sender names will look and behave just like normal.
- Messages from unregistered names will say “Unverified“, which could be a scam (but not always).
- Some legit businesses may still be getting set up when the register launches, so not all unverified messages are dodgy.
Will this change which SMS messages I get?
For most people, no.
You’ll still receive texts from your bank, telco or other trusted services if they’ve registered their sender IDs.
If not, their messages will still come through but will be marked “Unverified“. Over time, this will help reduce spoofed messages pretending to be big brands.
Do I need to do anything?
Nope – you don’t need to lift a finger.
But here are some smart tips:
- Look out for “Unverified” tags and think twice before clicking any links.
- Use scam filters built into your phone where possible.
- Report dodgy messages to Scamwatch or your mobile provider.
Key dates to remember
- 15 October 2025: Telcos and message providers can start joining the register.
- 30 November 2025: Businesses using sender names (like “MyBank”) must register them through a telco.
- 1 July 2026: Only registered sender IDs will appear as verified. Unregistered ones will be marked “Unverified“.
What if a trusted sender doesn’t register?
If a legit sender, like your bank or power company, hasn’t registered their name in time, you’ll probably still get their messages, but they’ll show up as “Unverified“.
We’re already working with our partners to make sure all our sender names are registered, so there’s no disruption for you.
Will this stop scam texts completely?
Not entirely – but it’s a big step forward.
The register helps block scammers pretending to be trusted brands, but some might still use random numbers or other tricks.
That’s why it’s important to stay alert and use any other scam-protection tools your phone offers.
