State license required — Illinois has no dedicated process server license, but 735 ILCS 5/2-202 allows only three routes: the sheriff (or coroner where the sheriff is disqualified); a person licensed or registered as a private detective under the Private Detective, Private Alarm, Private Security, Fingerprint Vendor, and Locksmith Act of 2004 (225 ILCS 447), or a registered employee of a licensed agency, who may serve in any county without special appointment; or a private person over 18 and not a party whom the court appoints by order on motion. The professional route in Illinois is a private detective license or agency registration under 225 ILCS 447, which permits service in any county without a special appointment; a private detective or licensed employee must supply the sheriff of any county where they serve with a copy of the license or certificate, though failure to do so does not invalidate the service. Otherwise a private person over 18 who is not a party must be appointed by court order on motion. A sheriff in a county under 2,000,000 population may employ civilian personnel to serve process, and in a county of 3,000,000 or more (Cook) a licensee hired to serve summons remits a $5 fee per service.
