WhoAU is an Australian phone number lookup tool that helps you search a phone number, identify possible business information, view community reports, and check recent lookup activity.
When you search a number, WhoAU checks available phone number records, business matches, public signals, and community reports. If a useful match is found, we show caller context to help you decide what to do next.
A result may include the phone number, possible company information, business context, community labels such as scam or spam, user-submitted notes, and recent search activity.
Yes, when the phone number is linked to a company record in our database. Some companies may use multiple numbers, so WhoAU is designed to support related business phone profiles.
If no company match is available, you can still review community signals or submit a report. Users can mark a number as scam, spam, telemarketing, safe, or other, and add useful context.
These labels come from community reports. Scam usually means users believe the call may be fraudulent. Spam refers to unwanted or repeated calls. Telemarketing usually means sales or promotional calls. These are signals, not official legal conclusions.
WhoAU may display how often a number has been searched over recent periods such as 3 days, 7 days, 14 days, or 30 days. This can help show whether a number is currently active in the community.
The core phone number lookup experience can be offered for free. Some advanced features, account tools, or future services may require sign-in depending on how the platform is configured.
You can search numbers without an account. If you register and sign in, you may be able to manage reports, marks, and other activity connected to your account.
Yes. Registered users should be able to view, edit, or manage their own submitted reports from their user dashboard.
WhoAU may use a combination of business phone records, public company information, structured database records, and user-submitted reports. Community submissions should be reviewed and treated responsibly.
WhoAU aims to provide useful caller information, but phone ownership can change and user reports may vary. Lookup results should be used as guidance rather than guaranteed identity confirmation.
WhoAU should focus on phone number lookup, business identification, and community caller reports. It should not display sensitive personal information such as financial records, criminal history, or private documents.
No. WhoAU is not a background check service. It is designed for caller lookup, business number matching, community reports, and communication safety.
Yes. WhoAU should provide a way for businesses or individuals to request corrections, updates, or removal of inaccurate information.
No. WhoAU is a web-based lookup and reporting service. It can help you identify and understand a number, but blocking calls must be done through your phone, carrier, or device settings.
WhoAU helps organise caller context, but community reports are signals rather than final proof. Always use your own judgement before sharing personal information, making payments, or calling back unknown numbers.
