Illinois Arrest Warrant Execution Verification is a tool used to verify whether a warrant has been served in Illinois. It allows law enforcement officials to check the status of an arrest warrant from any Illinois county to determine if it has been executed. Illinois Arrest Warrant Execution Verification is available in two types: online and direct contact. The online version is a web-based searchable database, while direct contact involves physically visiting a police station or sheriff’s office for verification. Both methods are used to ensure that valid arrest warrants have been served.
