To put it bluntly a Federal Search is a background check that seeks to find criminal offense records created in a Federal Court.  A National Criminal Background Check retrieves criminal records that were created in either a county or state court.  This is the fundamental difference between the two types of background checks offered by CriminalBackgroundRecords.com.

Typically if the crime committed crosses interstate lines than under Federal Law the case is heard at a Federal Court.  Federal cases include counterfeiting, racketeering, tax fraud etc., and also include cases that involve national security or specific federal institutions like the US Post Office.  A national background check pulls criminal records from county court houses and state courts for crimes committed in that specific jurisdiction
