How to check if a phone number is a scam
Who Called Australia editorial team · Updated: 31/08/2026
You can settle most "is this a scam?" questions in under a minute — if you check the right things in the right order. Here's the checklist we'd use, followed by the red flags that decide it instantly no matter what any database says.
The 60-second checklist
- Look the number up. Enter it in the reverse lookup: you'll see its type (mobile, landline, service number), the carrier holding the range in the ACMA register, and any community reports. A 190x premium number as a missed call is bait by definition.
- Read the reports.A number that's been running an "NBN disconnection" script for a week accumulates near-identical reports. The spam barometershows what's currently surging.
- Check the current scam scripts. Scamwatch publishes live alerts, and our guide to current phone scams in Australiadescribes the scripts doing the rounds — if the call matches one, you're done.
- Verify against the published number.If the caller claims to be your bank, the ATO, your telco: hang up, find the organisation's number on its official website or the back of your card, and call that. Never verify a caller using details the caller gave you.
Red flags that end the analysis
- Payment demanded in gift cards, crypto or bank transfer to a "safe account" — no legitimate organisation does this, ever.
- Remote access requests (AnyDesk, TeamViewer) "to fix your internet" or "stop a hack".
- Codes read over the phone: one-time passwords and SMS codes exist precisely so that only you have them. Anyone asking is breaking into something of yours at that moment.
- Manufactured urgency: arrest warrants, disconnection in 24 hours, "your account is being emptied right now".
- Secrecy: "don't tell your bank/family what this payment is for."
Why the display can't be trusted
Caller ID is a claim, not a credential. Spoofinglets a scammer display a real bank's 1300 number or a mobile one digit away from yours. That cuts both ways: a legitimate-looking number proves nothing, and an innocent person's number can appear on scam calls they never made. It's why our number pages label community content as opinion and why the behaviour of the call always outranks the number on the screen.
After the call
Report scams to Scamwatch — the reports steer real enforcement — and leave a rating on the number's page here so the next person who searches it gets their answer in one step. Lost money or details? Your bank first, then ReportCyber, and IDCARE (1800 595 160) for identity recovery.
Frequently asked questions
The number that called me has no reports anywhere. Is it safe?
Unknown isn't the same as safe. Scam operations rotate through fresh numbers precisely so they carry no history. Judge the call, not just the number: anyone asking for remote access, codes, gift cards or urgent transfers is a scammer regardless of what the display shows.
Where do I report a scam call?
Report the scam to Scamwatch (scamwatch.gov.au, run by the National Anti-Scam Centre). If you lost money or personal details, also file at ReportCyber (cyber.gov.au) and call your bank immediately. Leaving a report on the number's page here warns the next person the same number calls.
Can my telco block scam calls?
Australian telcos must detect, trace and block scam calls under the ACMA's Reducing Scam Calls code, and they silently block huge volumes. Nothing reaches zero though: whatever gets through, the checklist below handles.
I answered and said 'yes' — am I in danger?
The 'yes recording' scare is overstated in Australia: banks don't authorise payments from a recorded yes. The real risks are what you dial, share or install. If you gave out codes or card details, call your bank now; if you only spoke, you're fine — just report and block the number.
