How to Conduct a Business Entity Search in Illinois

Before you register and form your limited liability company (LLC), you need to make sure the name you’ve chosen is available in your state. If you choose a name that’s already in use, the state will deny your LLC application. So checking name availability is absolutely crucial. In Illinois, it’s a simple process — just follow the steps outlined below. 

Follow Illinois LLC Naming Guidelines

Like all states, Illinois has specific rules and restrictions when it comes to business names. You need to follow these or your preferred name could be rejected by the state. 

In Illinois, it’s important that your name must include the phrase “limited liability company,” or one of its abbreviations (LLC or L.L.C.), and your name cannot include words that could confuse your Illinois LLC with any government agency. Your name also cannot include words like “bank”, “insurance”, “university, or “fiduciary” without approval from certain state authorities. 

Additionally, your name must be distinguishable from all other business names in the state, and it cannot contain any terms or abbreviations that imply that the LLC is a corporation or partnership.

Next, enter your preferred name in the search box and press enter. Do this with similar names as well to see if businesses exist with similar names. If you find the name during your search, you’ll need to go back to the drawing board and choose a different name.

Before you register or reserve the name for your LLC, you should visit the website of the US Patent and Trademark Office to make sure it’s not already trademarked. If it has been, you’re not allowed to use the name. 

Checking for Domain Name

Check the availability of related domain names using our Domain Name Search tool. Using “.com” or “.org” sharply increases credibility, so it’s best to focus on these. Once you’ve finished your name checking process, you can register the domain name by choosing an ICANN-accredited registrar such as GoDaddy.

The fee for maintaining your domain name usually ranges from $10 to $20 per year. When you purchase the name, you generally must pay for the first year up front. 

Reserve or Register Your LLC Name 

Now that you know your preferred business name is available in Illinois, not nationally trademarked, and has an available web domain, it’s a good idea to take the next step and make it official. 

In Illinois, you have two options. You can either reserve the name here, which means the state will hold it for you for 90 days, or you can go ahead and formally register your LLC name here

The first option gives you more time to be absolutely sure you want to create a new business, while registering right away lets you start your entrepreneurial journey more quickly. The choice is yours. 

You should also consider trademarking your LLC name with the US Patent Office so it’s protected throughout the country.

Your business name is your business identity, so before you officially register your LLC it’s absolutely crucial to confirm that your preferred name is available. This will ensure you avoid any business naming potholes and set your LLC up for smooth sailing.
