Choosing a Corporation Name
The name you choose for your new Illinois corporation must be distinguishable from all other registered and reserved Illinois business entities. Like other states, Illinois state law mandates the use of some words and phrases, but restricts the use of others when it comes to business names.
For instance, your new corporation’s name must include one of the following words or their abbreviation at its end, or equivalent terms in another language: “Corporation,” “Incorporated,” “Company,” or “Limited.” It also must contain the word “trust”, “pawners,” or “cooperative” if the corporation is conducting these types of business.
The name must be made up of letters or symbols which the secretary of state’s office can reproduce, and it must be the name under which the corporation will conduct business, unless it has selected an assumed name (“doing business as”) in compliance with Illinois law. Assumed corporate names must be periodically renewed with the secretary of state’s office.
Additionally, your new Illinois corporation’s name must not contain terms that state or imply that the corporation is authorized to conduct business in insurance, assurance, indemnity, savings deposits, banking, or as a corporate fiduciary, unless it has been so authorized by the proper state agency.
Available corporate names can be reserved with the state for up to 90 days for $25
