Sender ID FAQs

Why Should I Register my Sender ID?

Starting 1 July 2026, new Australian regulations require all businesses sending branded text messages (e.g., messages appearing as ‘YourBank’ instead of a phone number) to register their Sender ID with the official SMS Sender ID Register. For more information, please visit the acma website - https://www.acma.gov.au/about-register

What Happens If I use a Sender ID that is not registered in ACMA?

To help protect consumers against scams, any branded messages from businesses that fail to register by this date will be automatically labelled as "Unverified" or may be blocked entirely.

What information should I have ready before submitting my Sender ID request to Tall Bob?

What would be the Business Name of Tall Bob in the ACMA Assist Portal?

Tall Bob is registered as an Originating and Transiting telco under the name Hyperlocal Pty Ltd. 

When Tall Bob submits the sender ID to ACMA for their customer, the Authorised Representative of that business will receive an email notification that begins with the following message:

“The Australian Communications and Media Authority has received an application from Hyperlocal Pty Ltd to register the following Sender ID for <company name> on the SMS Sender ID Register:”

* Authorised Representative: The authorised representative is not the person submitting the application. They must have legal authority to act on behalf of the legal entity e.g. listed on ABR Registry (CEO) or registered in ACMA as a business administrator.

Sender ID Requirements by ACMA

To be eligible for registration, Sender IDs must comply with the following ACMA requirements:

• Be 2–11 characters long.
• Use ASCII characters 32–126.
• Not consist only of numbers.
• Not contain spaces/underscores at the beginning or end.
• Not be misleading, deceptive, or offensive

  
  

It is important to ensure your Sender ID strictly follows these guidelines to avoid rejection during the registration process.

How to Set Up Your Business in the ACMA Register

Before registering a Sender ID, your business must first be set up in the ACMA system.

Please refer to ACMA’s official guide on accessing the register for the first time:

This guide outlines how to verify your business details and authorised representatives.
