If you’re a business owner in Illinois, chances are that sooner or later your company will have to file for a DBA. This guide is going to break down the whole process step by step. So whether you want a different business name or looking for a unique name for branding purposes, this guide will help- read on!

Important! Please keep in mind that DBA is not a business structure, so it won’t protect you from liabilities, lawsuits, or any other unforeseen situations. DBA stands for Doing Business As. – often precedes the name under which a business operates, which is not the legal name of the business.

Therefore, before starting, make sure you understand the difference between informal business structures such as sole proprietorship and formal ones like corporations and LLCs.

To register or renew the trademark, trade name, or service mark for your company in Illinois you need to file the application to the Secretary of State. Here is what you need to do:

Illinois Business Entity Search

Your company’s trade name should be unique and have not been acquired by any other entity in Illinois. Moreover, this name must also meet the business name requirements of Illinois.

First, you have to search the Illinois Secretary of State’s Business Search portal for the DBA, Business, & Fictitious names. Check the portal thoroughly to know whether the name that you wish to have for your business has already been taken by someone or not. Make sure, this name isn’t already in use.

Note: You can also find a complete guide on business name search here.

Once you are done searching, the next step is to review the naming requirements of the state of Illinois. Professional corporation and LLC naming guidelines help you learn about Illinois naming guidelines. In general, your DBA should not include:

  • Any term or abbrevation that is ristricted to government bodies only
  • Term that confuse your business with government institutions such as state department, FBI, treasury, etc
  • Any word or term indicating that your company is in the business of a corporate fiduciary such as such as trust, trustee, fiduciary unless permitted by the Secretary of Financial and Professional Regulation.
  • Terms indicating the business is some kind of financial institution, such as bank, insurance, or corporate fiduciary without authorization from the state Commissioner of Banks and Real Estate.
