There is no fee to search the database.
What information can be looked up?
The database search can find several pieces of information about the business. Some of the highlights include:
- Entity Name
- Status – Active means the business is in good standing with the state and all reports and filing fees are up to date
- Type of LLC – Corporation, Limited Liability Company. Etc.
- Registered Agent’s information – A Registered Agent is the singular point of contact for the entity should a legal or tax notice need to be sent to the business. This is often one of the owners and if their home address is used, that address becomes public information. Many people find this concerning and use a Registered Agent service like Northwest Registered Agent or IncFile so their home address isn’t listed.
- Principal Office – This could by the actual address of the business entity or it could be an address where the business records are stored.

How do I form an LLC?
Before starting your business and forming an LLC, be sure to do the business entity search first to make sure the name is available to use. Once you know the LLC name is available, learn how to form an Illinois LLC by reading our step-by-step guide on filing the Articles of Organization.
While not required in Illinois, an Operating Agreement, which are the rules for how the LLC operates, may be a document worth considering especially for multi-member LLCs.
After forming a Limited Liability Company, be sure to get an Employer Identification Number (EIN). This is a “social security number” for the business. There is no cost to get one through the IRS.
After forming the LLC, Illinois business licenses and permits may still be necessary.
