The story of 0409

Had a call from a 0409 number?
No clear pattern in reports on these numbers yet. If a call worried you:
- Call back on a number you trust
If a caller says they're your bank, the ATO, Services Australia, a courier or your telco, hang up and ring the organisation on the number from its website or your statement, never the number that called you. Caller ID can be faked.
- Report the call to Scamwatch
The National Anti-Scam Centre uses Scamwatch reports to warn others and to get scam numbers blocked. Note the number, the time and what the caller claimed to be. If anyone is in danger, call 000.
- Register on the Do Not Call Register
Registering landlines and mobiles is free and stops most telemarketing calls within 30 days. Charities, political parties, surveys and scammers aren't covered.
- Forward spam texts to 0429 999 888
The ACMA collects unsolicited commercial texts forwarded to 0429 999 888 (standard message charges apply). Don't edit the message first. Scam texts that impersonate a bank, toll road or delivery company go to Scamwatch instead.
