Calling line identification (CLI)
Your CLI is the number that is shown to the person being called when you make a call. You can make your phone number more private if you don’t want this number to be displayed.
Some businesses want to display a particular number as the CLI when they call customers. This makes make it easy for customers to identify them and call back. This is called ‘CLI overstamping’, and it is legal in Australia—as long as it is not being used for phone scams.
Talk to your telco if you want to use your particular number when making outgoing calls to customers.
In December 2020, we registered Industry Code C661:2020 Reducing Scam Calls. It includes new CLI rules for carriers and carriage service providers to help identify, block and reduce scam calls.
