New text rules to help Australians spot scams

New text rules to help Australians spot scams

New rules from the Australian Communications and Media Authority (ACMA) mandate organisations register their sender ID. From tomorrow, any texts sent from an unregistered Sender ID will appear as ‘unverified', in a move to help Australians detect scam messages. An RMIT expert explains. 

Associate Professor Mark Gregory, School of Engineering: 

"The initiative to introduce verified Sender IDs is a positive step that should reduce impersonation scams.

"It shows that the Government is working towards a reduction in the devastating impacts of scams and fraud.

"The new rules will require that all branded Sender IDs must be registered and linked to the actual company or organisation. This will mean that legitimate SMS messages will be received without a message saying the sender is 'unverified'."

Mark Gregory is Associate Professor in the School of Engineering at RMIT University. He researches telecommunication networks, systems and services.
