Illinois Code § 3

§ 3.

In proceedings under this Act, summons shall issue and be served as in other civil actions, except that service shall be had in the county in which the principal office of such corporation is by its charter located. If process is returned not found, the Attorney General shall cause publication to be made as in other civil actions in a newspaper of general circulation published in the county where the principal office of such corporation is located. The publication shall contain a notice of the pendency of such action, the title of the court, the title of the case, and the date on or after which default may be entered. The Attorney General may include in one notice the names of any number of corporations against which actions are then pending in the same court. The Attorney General shall cause a copy of such notice to be mailed to the corporation at its registered office within 10 days after the first publication thereof. The certificate of the Attorney General of the mailing of such notice shall be prima facie evidence thereof. Such notice shall be published at least once each week for two consecutive weeks and the first publication thereof may begin at any time after summons has been returned. Unless a corporation shall have been served with summons, no default shall be taken against it earlier than 30 days after the first publication of such notice. (Source: P.A. 86-1328.)
