Who has held it
Allocated to Telstra Limited, now held by Optus Networks Pty Limited since 2006. The network above is the current holder, not the company the number started with.
How it is licensed
Licensed directly by a business rather than rented through a number broker, so whoever holds it is likely to be whoever answers it.
The national numbering register lists QBE as the holder of this number. Check the register.
That does not make an incoming call from this number safe. Caller ID is easy to fake, and impersonating a known number is exactly how these scams work. If someone called you claiming to be QBE, hang up and dial the number yourself, taken from their official website rather than from the call.
How often people look this number up
Looked up 5 times since 18 October 2026, 5 of them in the last seven days.
People look a number up when they do not recognise a call, so this tracks how widely 13 37 23 is being dialled, not how many people answered.
