SMS Sender ID Registry - Fighting SMS Impersonation Scams

We are seeking your feedback on the type of SMS Sender ID Registry that should be implemented in Australia. 

Why we want your input

The Australian Government is seeking feedback on the type of SMS Sender ID Registry that should be implemented to help prevent SMS impersonation scams. These are scams where criminals impersonate alphanumeric sender IDs (e.g. AusPost or myGov). We want to hear from interested stakeholders, including businesses and charities that communicate with their clients via SMS as well as consumers and businesses receiving these scam messages.

How you can voice your opinion

Feedback can be provided by email to or uploaded via the “Have your say” button below.

Alternatively, you can choose to complete a short 5-10 minute survey via the Start Survey button below.

What will be the outcome of this consultation?

Your feedback will help inform government decision-making on whether the registration of alphanumeric sender IDs should be mandatory or voluntary.

The Issue

A common method used by scammers involves using SMS with fake sender IDs to imitate trusted brands such as ‘Linkt’ or ‘AusPost’, and deceive victims into giving over personal information or money. 

Scam SMS are often difficult to distinguish from legitimate SMS communications, meaning they pose an increased threat to both consumers and legitimate businesses and organisations. 

On 23 April 2023, the Minister for Communications announced plans to establish an SMS Sender ID Registry (the registry) as part of the government’s agenda to combat scams. The registry will protect consumers and brands by helping telecommunications service providers to identify and block SMS impersonation scams before they reach their target. 

On 15 December 2023, the ACMA launched a pilot of the registry, based on a voluntary model, with selected brands able to choose whether or not to register their sender IDs. SMS using these alphanumeric sender IDs will be blocked, unless they are sent by an authorized party. However, SMS using an unregistered sender ID will not be blocked, and can still be sent and received. 

The government is now considering whether to make registration voluntary or mandatory for alphanumeric sender IDs. 
We are seeking your feedback by 20/03/2024 on whether you support the introduction of a mandatory SMS Sender ID Registry or a voluntary registry.
