Revealer.US username lookup searches a submitted username, email, or phone number across 800+ social, gaming, forum and developer platforms in real time. It identifies platforms where the username/identifier is publicly exposed and can follow reused handles to surface potentially linked accounts. Unlike a conventional database search, Revealer.US states that it does not maintain or own the underlying personal-information database. Instead, it queries public and third-party sources when a search is performed and returns the information provided by those sources. **The lowdown:** It’s useful when you have a single username/online handle, email address, or phone number and want to establish its wider public footprint. ### How to Use: **1. Enter a username, email address, or phone number into the search bar.** **2. Run the search and review the returned platforms and profiles.** **3. Record relevant results and pivot to the original platform to verify them.** ### Cost * [ ] Free * [x] Partially Free * [ ] Paid A free tier provides username lookups and preview results. Paid plans provide additional functionality, including full reports and unlimited searches. ## Data Processing ### Account Required: * [x] Yes * [x] No No for the demo search. Yes for full functionality. ### Cookies: Revealer.US uses an auth-token cookie containing a signed JWT to maintain authenticated user sessions. The cookie is marked Secure and HttpOnly with SameSite=Lax. The site also sets a g\_state cookie associated with Google authentication/Identity Services. These are primarily authentication and session-management cookies rather than advertising cookies. ### Use in Reporting Revealer Username Lookup can be used to: * Identify public accounts associated with a particular username or handle. * Search for the same username across social-media platforms. * Identify reuse of a username across gaming platforms. * Identify forum accounts using the same handle. * Identify developer accounts associated with a username. * Establish the potential public online footprint of a username. * Identify potentially related accounts through username reuse. * Generate investigative leads for further OSINT research. * Identify accounts that may warrant further examination in fraud, impersonation or threat-intelligence investigations. * Corroborate the existence of a username across multiple public platforms. * Pivot from a username to additional publicly available identifiers and online profiles. * Support investigations into online identities, subject attribution, fraud and abuse. * Provide a starting point for further verification using the original platforms. Reporting caveat: A username match alone should not be reported as proof that multiple accounts belong to the same individual. The username should be corroborated with additional independent indicators.

| **Capabilities** | **Limitations** | | ------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------- | | Searches usernames across 800 platforms, emails across 200 platforms, and phone numbers across 10 platforms. | A username match does not prove that accounts belong to the same individual | | Covers social, gaming, forum and developer platforms. | Passwords are redacted. | | Performs searches in real time. | Platform coverage and search results may change over time. | | Can follow reused handles to identify potentially related profiles. | Results depend on information currently available from third-party/public sources. | | Free tier available for username searches and preview results. | Full reports and additional functionality require paid plans. | ### Summary Revealer Username Lookup can identify where a username is publicly exposed and follow reused handles to surface potentially related accounts. It is therefore particularly useful as an initial discovery and pivoting tool. However, sometimes the same individual may not carry the same username across all platforms and it will return false positives. Important findings should be checked against the original platform and corroborated with independent identifiers before being included as a factual attribution in an investigative report. ### Ownership American / Thai owners Bob Adams and ‘Pat’. ### Ethical Considerations * Treat username matches as leads rather than definitive attribution. * Verify important findings against the original source. * Be particularly careful where results include breach or other sensitive data. * Avoid publishing personal information that is unnecessary for the investigative purpose. * Record the date of the search because results from live sources can change. ### Related Tools: * [OSINT Industries](/osint-tools/osint-industries.md) * Sherlock * [Epieos](/osint-tools/epieos.md) * [Have I Been Pwned?](/osint-tools/have-i-been-pwned.md) #### Sources *With thanks to Bob Adams for submitting this tool to the OSINT Tool Library.*
