Guidelines to Follow in Naming LLC

  •  Use a business name with the abbreviation “LLC” or the phrase “Limited Liability Company.” 
  • Your decided business name must not coincide with any existing government entity. Otherwise, you might have to face legal lawsuits when filing your LLC.
  • Use the LLC name availability checker to ensure your business name is unique.
  • Get a license first if you plan on using restricted words to avoid any complications.

Note that you must put adequate effort into naming your LLC because this name will be with your business for a long time. Making your LLC name unique is vital as it would prevent people from confusing your business with others, not to mention it would be easier for them to recall your business, products, or services.

How To Do an Illinois LLC Online Name Search

As a part of your LLC registration process, it is important to have a suitable name for your LLC in accordance with the State naming guidelines. So, when you select a name for your LLC, you also need to run a quick search on the Illinois Business Entity Search page to check whether the name is unique and there is no other business running in the State with the same name.

1. Access the Business Entity Search Tool on the State website

The Illinois Secretary of State website offers a Business Entity Search Tool to assist you in finalizing a name for your business LLC. This tool is helpful in deciding the uniqueness and availability of the name. Also, keep a list of backup names ready, so you can select a final name in a few attempts.

2. Run the Search

After you navigate to the Search page, you can run the search by Business name. To begin the search process, you need to enter the name in the blank space under the ‘Entity name’ heading and then click on the “Search” tab after clearing the captcha.

Perform the Search

You can also conduct the search using other available options, such as Name, Keyword, or partial word. Using such filters can give you more refined results such as giving you the list of businesses running with exact names, or having similar keywords, or even a single matching word.

While conducting the search, you can exclude usage of identifiers such as “LLC” to access wider results from different forms of business structures running in a similar name. Conduct thorough research of the name by using the provided filters before filing it with the Authorities. You can also refer to the ‘Search instructions’ provided on the search tool page.

If you also wish to use a Trademark for the distinct identity of your business in the State, you can run a trademark search on the Trademark Database of the U.S. Patent and Trademark Office to see whether the chosen name is already in use by any other business entity.

If you also plan on conducting your business online through a website, you should also check if a domain name similar to your chosen business name is available or not.
