Preparing for ACMA’s New Sender ID Rules

Before you get started: What you need to know

What’s happening

The Australia Communication and Media Authority (ACMA) will require businesses to register their Alphanumeric Sender IDs (the name that appears as the SMS sender) to prevent scams and spoofing. To keep sending SMS through Reapit, your Sender ID must be registered and approved prior to July 1 2026.

In order for Reapit to continue sending SMSs on your behalf from your Sender ID and ensure they are delivered, two steps need to be completed prior to July 1:

1. You will need to have completed ACMA Assist account setup (Step 1) prior to 1 May 2026 in order to approve your sender ID for use.
2. Reapit will submit ALL Alphanumeric Sender IDs currently in use in Reapit Sales, Reapit Lettings, Reapit PM, and/or Move Me In to our SMS delivery provider, who will prepare them for approval by ACMA. This bulk send will be completed from 1 May 2026.

Who is ACMA?

ACMA (the Australian Communications and Media Authority) is the government regulator responsible for enforcing SMS scam‑prevention rules. They manage the approval process for Alphanumeric Sender IDs through their system, ACMA Assist.

Why this matters to you

Your Sender ID must be approved by ACMA before it can be used to send SMS through Reapit. Without approval, unregistered Alphanumeric Sender IDs will appear as Unverified in messages sent to recipients.

What’s involved in registering a Sender ID

Alphanumeric Sender ID registration involves both ACMA and our SMS delivery partner, and the process spans between two systems before a Sender ID can be used in Reapit to send SMS messages to your clients:

1. Your Authorised Business Representative (ABR - see below) sets up ACMA Assist.
2. The ABR can approve Sender ID registrations themselves or delegate approval to an authorised ACMA Assist user.
3. Alphanumeric Sender IDs are submitted in bulk by Reapit to our SMS delivery provider and must be approved in ACMA Assist before they can be used to send SMS via Reapit software.
4. ACMA will notify the authorised ACMA Assist user by email, and the authorised user must log in to ACMA Assist and approve the request before the Sender ID can be used.

Key roles in this process

• Authorised Business Representative (ABR) - The ABR is the is the primary contact listed for your business on the Australian Business Register, and the person within your business who manages the business’ ABN. Only the ABR can initially set up ACMA Assist. Reapit cannot help you to identify this person, nor can we set up ACMA Assist for you.
  • If you are not sure who the authorised business contact is for your real estate office, we recommend that you ask your legal or finance team who may be able to help.
• Authorised ACMA Assist User - An Authorised ACMA Assist User is someone the ABR has approved (or delegated to) to approve Sender ID registrations. This may be the ABR themselves, or another person in the business.

Step 1: Set up ACMA Assist (ABR only)

This step must be completed by the Authorised Business Representative (ABR).

What this step does

For clients who already have a sender ID registered with Reapit, they must also have an active ACMA Assist account and ensure their Sender ID is approved through ACMA Assist. This approval is required to ensure that SMS messages we send on their behalf continue to be delivered after 1 July 2026.

This step activates your ACMA Assist account so Sender ID registrations can be reviewed and approved.

What you need before you start

• Identify your Authorised Business Representative (or ABR)
• The ABR needs to download the MyID app, with identity verified to Standard level. Ensure your ABR has access to the business ABN.

Delegating to another authorised ACMA Assist user:
If your ABR is not the best person to approve your Alphanumeric Sender ID/s going forward, your ABR will be able to delegate this to another Authorised ACMA Assist User. Please note, the initial ACMA Assist account setup will still need to be completed by the ABR before this delegation can occur.

ACMA Assist setup

Follow ACMA’s official guide for businesses and organisations. It covers:

• Logging in to ACMA Assist
• Adding your ABN
• Approving Sender ID registrations
• Delegating approval to another Authorised ACMA Assist User (optional)

Step 2: Submit Alphanumeric Sender IDs (Reapit)

Once ACMA Assist is set up, Reapit will submit ALL Alphanumeric Sender IDs currently in use in Reapit Sales, Reapit Lettings, Reapit PM, and/or Move Me In to our SMS delivery provider, who will prepare them for approval by ACMA. This bulk send will be completed from 1 May 2026.

If 1 May 2026 has passed and your ABR has not set up your ACMA Assist account, please contact Reapit Support as soon as possible.

Step 3: Approve the registration in ACMA Assist (ABR)

After your Sender ID has been verified through ACMA:

• ACMA will notify the Authorised ACMA Assist User by email
• The Authorised ACMA Assist User must log in to ACMA Assist and approve the request

The Sender ID will no be registered until this approval is completed.

If you’re blocked

I’m not the ABR - what should I do?

Identify your ABR (i.e. the person who manages your business' ABN) and direct them to Step 1 of this guide. They must complete the ACMA Assist setup before anything else can happen.

Can the ABR contact delegate approvals?

Yes. The ABR can delegate approval rights to another Authorised ACMA Assist User once the initial ACMA Assist setup is completed. Instructions for approving or delegating access are covered in ACMA’s official user guide: SMS Sender ID Register user guide for businesses and organisations | ACMASMS Sender ID Register user guide for businesses and organisations | ACMA

What happens if I don’t register?

From 1 July 2026, all unregistered Alphanumeric Sender IDs will appear as Unverified in messages sent to recipients.
