What You'll Learn

Use a scam phone number lookup tool
A scam phone number lookup tool is a reverse phone lookup service that allows you to enter a number and see public information associated with it, such as the registered name, location, and carrier. Some scam phone number lookup tools include Scamio, Cybertrace, and Reverse Australia.
Cybertrace's Scam Phone Number Lookup tool is free and allows users to check phone numbers and get instant access to caller information. They also offer a premium investigative tool that provides a deep scan of phone numbers, allowing users to discover names, usernames, caller IDs, contact details, profile images, and social media accounts.
Reverse Australia is another free scam phone number lookup tool that allows users to look up suspected scam numbers and report them. This platform provides a quick and easy way to learn more about suspected scam numbers and report them to the relevant telecommunications provider for assessment.
While some scam phone number lookup services are free, others may require a paid subscription for more detailed reports. It's important to note that scammers often use technology to make their numbers appear as if they're calling from local area codes or legitimate organizations, and reverse lookup tools may not always be able to identify these spoofed or unlisted numbers.
In addition to using scam phone number lookup tools, you can also utilize your carrier's spam blocker app to identify and block known scam numbers. Most smartphones also have built-in settings to silence or block calls from unknown numbers.

Contact a licensed private investigator
If you are unable to identify an unknown number using reverse phone lookup websites, search engines, or social media, you may want to consider contacting a licensed private investigator. In Australia, engaging a private investigator is legal, and they are licensed to gather private information, investigate, and conduct surveillance.
Licensed private investigators in Australia can utilise various databases, investigative techniques, and tools to help trace a phone number. They can employ methods such as discreet enquiries, social engineering, location services, and skip tracing to find the person behind an unknown number. Social engineering, for example, involves calling the number and pretending to be a survey company or legitimate entity to gather information about the owner of the number. Private investigators can also use Open-Source Intelligence (OSINT) tools and methods to gather information from publicly available sources, including the internet, dark web, deep web, social media, news articles, and other public data sources.
It is important to note that private investigators must operate within the law and obtain the necessary permissions and legal documents before carrying out any investigation. They are restricted from accessing protected information such as medical records, social security numbers, and personal financial information.
There are several private investigation agencies in Australia that offer phone number identification services, including Infidelity Investigators, National Inquiry Agency, and Trace and Identify. These agencies have experienced investigators who can help identify the person behind an unknown number. Some agencies offer different packages with varying levels of depth and scope, and they usually charge an hourly rate plus database costs.
Before engaging a private investigator, it is essential to understand that privacy restrictions may limit the results, especially for Australian-based numbers. Additionally, no one should guarantee a search before conducting it, and there may be cases where a private investigator cannot locate an individual due to a lack of a paper trail or the person residing internationally.
If you decide to proceed with hiring a private investigator, you can contact them via phone, email, or online forms available on their websites. Be sure to discuss the details of your situation, the pricing, and any relevant restrictions or challenges they may encounter during the investigation.

Identify the network provider
In Australia, phone numbers are managed by ACMA (Australian Communications and Media Authority) which allocates numbers to telcos, which then assigns numbers to their customers.
There are several free reverse phone lookup tools available online that can help identify unknown numbers. These tools can provide information such as the name, username, caller ID, contact details, profile image, and social media accounts associated with a phone number. Some popular options include Cybertrace's Scam Phone Number Lookup tool and Reverse Australia. These tools can help protect against scam calls and provide instant access to caller information.
Additionally, some sources suggest that individuals with skip tracing tools may be able to identify the exact mobile network a phone number is connected to. However, this method may be complicated and time-consuming.
It is worth noting that scam callers may use spoofing techniques, making it difficult to identify the true owner of a number. In such cases, it may be pointless to try to locate the carrier or owner of the number.
Moreover, free carrier lookup tools are also available online, which can provide validity, carrier, and location information about each phone number. These tools are often used by businesses to improve their customer databases and messaging delivery rates.
