The Deadline
From July 1, 2026, any business SMS sent from an unregistered sender ID gets flagged 'Unverified' on customer phones. Registration opened November 30, 2025. The cutoff is May 15, 2026. That is 11 days.
What Happens to Unregistered Messages
Unverified texts get grouped into a single thread with actual scam messages. Your appointment reminder sits next to fake ATO phishing attempts. Telcos may block them entirely. Customers trained to ignore scam texts will delete yours without reading it.
Registered sender IDs display your business name. Unregistered ones say 'Unverified' where your brand should be.
Who This Hits
Any organisation sending branded SMS: appointment reminders, delivery updates, security codes, sales follow-ups. SMEs, enterprise, government agencies. Does not matter if it is marketing or transactional. If you send it with a branded sender ID, you register it.
Sales teams relying on SMS for meeting confirmations, sample shipment alerts, or contract reminders lose a channel if they miss this deadline. BDRs using SMS for outreach, same problem.
The Registration Process
Register through your telco or electronic messaging service provider. You need ABR details and proof of brand ownership (trademark or domain). ACMA says applications can take weeks. Anything submitted after May 15 risks missing the July 1 enforcement date.
Why This Exists
Australians lost $13.8 million to SMS scams in nine months of 2025. The government's response: a mandatory register to separate legitimate business texts from impersonation fraud. The trade-off is compliance overhead for every business using SMS.
The Sales Angle
If your sales process includes SMS touchpoints, this is not optional. Unverified messages get ignored or blocked. You lose delivery confirmation, meeting reminders, contract alerts. Check with your SMS provider now. If you are waiting until June, you are too late.
ACMA member Samantha Yorke's point stands: messages marked 'Unverified' get deleted. Customers are trained to distrust them. That is your pipeline sitting in a scam folder.
