Law Enforcement Information Sharing Service

Overview
The Law Enforcement Information Sharing (LEIS) Service is a web-based data exchange platform, hosted by the Department of Homeland Security (DHS), that allows law enforcement agencies to rapidly share and access data related to criminal and national security investigations.

The automated LEIS Service offers a more efficient system for requesting and sharing investigative information, helping investigators to more quickly identify patterns, connections and relationships between individuals and criminal organizations.

DHS law enforcement information in LEIS Service is processed through the ICE Pattern Analysis and Information Collection System (ICEPIC) and includes information from subject records and closed cases concerning people, businesses, vehicles (including aircraft and seacraft), firearms and more.

The LEIS Service currently provides federal, state, local, tribal and international law enforcement agency partners with access to more than 2.6 million subject records related to persons of interest, including suspects in child pornography, drug smuggling, immigration fraud, alien smuggling and a wide range of other cases.
