What is UserSearch

UserSearch is a reverse lookup tool that checks hundreds of websites to determine if a username or email address is currently registered at that website.

What is a Reverse User search ?

A reverse username search lets you search and find information regarding a person or a particular user profile, based on their social media profile username. It will search hundreds of websites for that username. The goal is to determine the identity of the person using the username. The second goal is to determine if that user is currently registered on a website, but in vast quantities, and quickly. Finally, the ultimate goal is to quickly find the public profile for that username and browse their activity based on what is publicly available online.

What is the difference between a Reverse Username Search and a Reverse Email Search?

There is not a huge amount of difference. However, reverse username searching, typically returns a lot more result (although they can be false-positives). Social Media websites and dating websites will usually leave a user profile public to view and have the username as the identifier to view that profile. They do not however, publicly advertise the email address on the same page, this is considered private information in most jurisdictions. Therefore, in order to perform a reverse email search, and for it to be successful, one of three conditions must be met:

1)The website has been instructed by the user to allow their email to be public. Websites such as LinkedIn and business networking social networks typically do this.

2)The user themselves have included their email address within their personal description or introduction.

3)The website allows manual checking via the registration of a email address, if a current email address has been registered. They then include this within an API (a public accessible function), which reverse email searching tools can then query. We at UserSearch utilise all three methods to try and perform a reverse email search for you. Rest assured, if the email address has been made public, our website will find it.
