Commonwealth Law Enforcement Assistance Network (CLEAN)

Through CLEAN, criminal justice agencies in Pennsylvania can message partner agencies and access information from Commonwealth sources, plus networked national, Federal, and international systems.


CLEAN is used by the Commonwealth's criminal justice agencies to access:

  • Driver license and motor vehicle information
  • State criminal history record information maintained in the Pennsylvania State Police Central Repository
  • The Commonwealth's central registry for Protection from Abuse orders
  • "Hot" (stolen and wanted) files
  • Law enforcement messaging capabilities, and a host of other services

CLEAN is Pennsylvania's conduit to the National Crime Information Center (NCIC), the FBI's National Crime Information Center, and to Nlets, the International Justice and Public Safety Information Sharing Network. CLEAN maintains connections to over forty other networks, including the Pennsylvania Justice Network (JNET). JNET interfaces with CLEAN to access criminal history information, arrest data, protection from abuse information, and "hot" files.

CLEAN handles 1.9 to 2.1 million transactions daily with an average turnaround time of 2.5 seconds each.

Access and administration

CLEAN access and the use of criminal justice systems and information is restricted to criminal justice agencies. The CLEAN Administrative Section in PSP's Bureau of Communications and Information Services is responsible to the FBI's Criminal Justice Information Services (CJIS) Division to ensure that NCIC regulations are enforced among Pennsylvania NCIC users.

The CLEAN Administrative Section:

  • Prescribes regulations for CLEAN system use
  • Conducts user training
  • Audits transactions to maintain system security and discipline
  • Investigates allegations of misuse of information systems
