- Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).
- Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
- Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your LLC.
- Your name must be distinguishable from any other Illinois limited liability company, corporation, limited liability partnership, or limited partnership.

3. Is the URL available? We recommend that you check online to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL in order to prevent others from acquiring it.
