New SMS Sender ID Rules Are Coming: What Real Estate Agencies Need to Do
Text messaging has become part of everyday business for real estate agencies.
Whether you’re confirming inspections, sending auction reminders, arranging settlement dates, following up prospective buyers or communicating with landlords and tenants, SMS remains one of the fastest ways to stay connected.
But from 1 July 2026, agencies using branded SMS messages need to be aware of a new requirement introduced by the Australian Communications and Media Authority (ACMA).
The new SMS Sender ID Register is designed to reduce impersonation scams by verifying the identity of businesses sending branded text messages.
While the change is relatively straightforward, agencies that don’t register may find their SMS messages displayed as “unverified”, potentially affecting client trust and engagement.
Here’s what the new rules mean for real estate businesses and what you should be doing now.
Why this matters for real estate agencies
Trust sits at the centre of every property transaction.
Clients regularly receive SMS messages from their agent about:
Open homes
Inspection times
Auction reminders
Contract updates
Settlement dates
Rental inspections
Property management communications
Maintenance updates
If those messages appear suspicious or unverified, clients may ignore them altogether or question whether they’re genuine.
The Sender ID Register has been introduced to help consumers distinguish legitimate organisations from scammers and reduce SMS impersonation fraud.
For agencies, it’s another way to protect both your brand and your client relationships.
What should your agency do now?
Before 1 July 2026, consider taking the following steps:
Identify whether your agency sends branded SMS messages using your business name rather than a mobile number.
Speak with your CRM provider, SMS platform, property management software or marketing provider about registering your Sender ID.
Check that your Australian Business Register (ABR) details are current, particularly your authorised contacts.
Review every system that sends SMS messages on behalf of your agency, including:
CRM platforms
Property management software
Inspection booking systems
Marketing automation tools
Auction software
If your business uses multiple Sender IDs, ensure each one is registered.
It’s about more than compliance
While these reforms are aimed at reducing scams, they also highlight something much bigger. Clients are becoming increasingly cautious about digital communication. Every text message your agency sends reflects on your professionalism. A verified Sender ID helps reassure clients they’re communicating with the right business and reinforces trust throughout the property journey.
