In the United States, the employer could use criminal records as verification as long as the employer does not discriminate based on race, color, religion, sex or national origin, as analyzed under the disparate treatment and disparate impact frameworks. There are several types of criminal record searches available to employers, some more accurate and up to date than others. These "third party" background checking agencies cannot guarantee the accuracy of their information, thus many of them have incomplete records or inaccurate records. The only way to conduct an accurate background check is to go directly through the state. Most times using the state of choice is much cheaper than using a "third party" agency. Many websites offer the "instant" background check, which will search a compilation of databases containing public information for a fee. These "instant" searches originate from a variety of sources, from statewide court and corrections records to law enforcement records which usually stem from county or metro law enforcement offices. There are also other database-type criminal searches, such as statewide repositories and the national crime file. A commonly used criminal search by employers who outsource is the county criminal search.
