A 15: For a record to be declared a positive match, at least two components (First & Last Name, Date of Birth, and/or Social Security Number) of the personal identifier information supplied must be an exact match to the criminal history record on file. Because at least two of the personal identifier components supplied must match exactly, it is important to provide as much information as possible, including maiden, alias, or nicknames used on each search. For instance, when searching the name Robert Smith, it may prove beneficial to include the name Bob Smith as a possible alias. MACHS allows up to two maiden or alias names to be searched in addition to the initial name within a single inquiry.

Examples of Inquiries that Match:
  • Match on First Name, Last Name, Date of Birth, and Social Security Number = Match

  • Match on First Name, Last Name, and Social Security Number = Match
  • Match on Alias First Name, Alias Last Name, and Date of Birth = Match
  • Match on Date of Birth and Social Security Number = Match

Examples of No-Match Inquiries:
  • None of the Identifiers supplied match a record = No Match
  • Match on First Name and Last Name Only = No Match
  • Match on Date of Birth Only = No Match
  • Match on Social Security Number Only = No Match
