Finding a person by his or her cell phone number is called a "reverse" lookup. This means that a piece of impersonal data (address, phone number, social security number) becomes the main informational data used to perform the search. Instead of looking up the person's phone number using his or her name, the cell phone number is utilized to find the name and location of the individual in question.

Many people search by this method if they are receiving calls from another cell phone that they do not recognize. It can also be used to verify the identity of someone who is selling something over his or her cell phone. Fraudulent claims can often go unchecked, especially if the actual identity of the caller is completely different from how he presents himself over the phone.

Some cell phone companies provide services to find a person by the cell phone number, but usually only for those people who wish to be found by this method. However, many companies that specialize in background checking offer ways to find a person by his or her cell phone number. They typically offer this service through a website, where customers can type in the cell phone number they wish and purchase any information the online search engine comes up with.

How and Why Businesses Find a Person by Cell Phone Number

Background checks are extremely important in today's hiring process and have included the method of finding out information about someone through their cell phone number. Many companies, especially security-driven businesses and governmental firms, often choose to take matters into their own hands and perform screening procedures to make sure the people they hire are legitimate and trustworthy. It is actually quite common for a company to create a full-fledged business alliance with a service that offers these and other ways to perform pre-employment background checks.
