Comprehensive background checks are used in a number of ways in today's society and are increasing in importance each year. Many companies use these background checks to determine whether a person is eligible for an employment position. Sometimes, individuals that are looking for someone to work for them personally, like a nanny for their children or a housekeeper for their home, will use a comprehensive background check to make sure that they can trust the person that they are allowing into their home.

Websites that offer comprehensive background checks can be found on the internet offering services that range from free to hundreds of dollars for each report. The level of detail included within the report will differ depending on what website the report is obtained from with the more expensive background check reports generally having the most accurate information and the highest level of detail.

There are a number of different items about a person's past that may be included in comprehensive background checks, depending on how detailed the background check is. Most background checks will include the person's residential, employment, and criminal history, with the more detailed reports including information about the person's assets, real estate holdings, and credit information.
