The story of 0420
0420 is the most fragmented mobile window in the register: six allocations to five different holders — Pivotel Satellite (from 24 September 2003), Vodafone Australia (an 800,000-number arc originally allocated to Vodafone Network in 2005), Sydney Trains (2008), Sinch Australia (2012) and Symbio Networks (2017) — with the newest row, a second Pivotel arc, dated 28 May 2026. It is the window the ACMA has used to seat smaller and specialist operators beside a major carrier.

Had a call from a 0420 number?
Most verdicts and reports on these numbers describe scam calls, so treat an unexpected call as a possible scam.
- 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.
- If you lost money or shared details
Call your bank straight away on the number on your card and ask it to stop the payment. Then report it through ReportCyber, which passes cybercrime reports to your state or territory police. If your identity documents or passwords were shared, IDCARE's free support service can help you lock things down.
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.
