Worth knowing
- The prefix tells you where a line was issued, not who is calling: range data is not personal data, and the number on your screen can be spoofed.
- Report scam calls to Scamwatch; unwanted telemarketing can be reported to the ACMA once your number has been on the Do Not Call Register for 30 days.
