What information can be looked up in the Illinois business name database?
The business name search can find several pieces of information about the business. Some of the highlights include:
- Company Name
- Status – Active means the business is in Good Standing with the Illinois Secretary of 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, so their home address isn’t listed.
- Principal Office – This could be the business entity’s actual address or an address where the business records are stored.
Something to keep in mind is that even though each Corporation and LLC name must be unique, it may not stop someone else from using that name since business names for a sole proprietorship or partnership are not registered by the Illinois Secretary of State and are not required to be unique. To protect your business name, consider getting a trademark.
