The story of 0452
0452 is a Vodafone window with a hole in it: the register gives Vodafone Australia the 700,000-number arc 0452 000–699, allocated on 11 August 2010, then leaves 0452 700–919 spare before a single 10,000-number block at 0452 92x, allocated to NetSIP Pty Ltd on 24 May 2023. Everything above 0452 93 is still unallocated, so a number there cannot be a live Australian mobile.

What does a call from a 0452 number mean?
A 0452 number below 0452 700 sits in the Vodafone arc and is an ordinary mobile; 0452 92x numbers belong to a small wholesale block and are often business or virtual-number services rather than a handset in someone's pocket.

Had a call from a 0452 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.
Nationally, Scamwatch recorded $72.5 million lost to scams that started with a phone call in 2025 (down from $107.2 million), with a median loss of $3,800 per report that lost money, and phone-call scam reports are 73.7% below their 2021 level. Telcos blocked 109.3 million scam calls and 45.2 million scam texts in January to March 2026. Sources: Targeting scams 2025 (National Anti-Scam Centre); ACMA quarterly report, Jan–Mar 2026.
