Reports indicate there are approximately 4 million illegal aliens in the United States and over a million criminals at large. Hiring and training expenses and potential liability, far outweigh any nominal background search fee. Individuals who wish to conceal their true identity information will often use multiple social security numbers, dates of births, and alias names. Many criminals will also transpose numbers or even use deceased or retired SSN's to hide a less than perfect past. This search is designed to help detect, reduce, or prevent such inappropriate and/or unlawful conduct.
