The story of 0411
0411 is the first of the three windows in the oldest row of the mobile register: a single three-million-number arc, 0411 000 000 to 0413 999 999, allocated to Singtel Optus Pty Limited on 10 July 1992 — the earliest allocation date the register holds — and transferred to Optus Mobile Pty Limited on 30 January 2003, when the Optus mobile ranges were consolidated under one licensee. Optus switched on Australia's first GSM network in 1993, and 0411, 0412 and 0413 were the numbers it issued to its earliest digital customers. Because the arc has never been split, the register carries exactly one row for the whole window.

What does a call from a 0411 number mean?
A 0411 number can date from the first years of Australian GSM, so many have cycled through several owners — worth remembering when community reports about a number look contradictory across years. Standard mobile rates apply; the range holder of record is Optus Mobile, but after porting the SIM may sit on any network.

Had a call from a 0411 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
