Illinois Business Name Search
Even with the help of business services through the Secretary of State (SoS), registering a business has financial consequences. Always discuss business setup with a business attorney.
How to search Illinois business names
Prospective business owners must search the Illinois Secretary of State to determine name availability before reserving or registering a new entity name. Illinois’ business entity search is a simple search that allows a business owner to search corporate and limited liability corporations at the same time.
Step 1: Navigate to the Illinois Secretary of State’s search tool.
Step 2: Ensure the radio button for “Corporate and LLC” is selected.
Step 3: Click the ‘Submit’ button.
Step 4: A new page opens. Choose the search type “Name” by ensuring the radio button is selected.
Step 5: Enter the business entity name in the search box.
Step 6: Click the “Continue” button.
The system will tell you whether it found matches based on the search criteria. If the system finds results, it displays exact matches and similar names. A business owner must choose another name if there are exact matches.
Additionally, a business owner may not use a similar name. For example, if the only difference is a word such as ‘a,’ ‘an,’ or ‘the’, the business owner cannot use the name. If the only difference is the entity type, the business owner cannot use the name.
To search for a limited partnership or a limited liability partnership, navigate to the Illinois Secretary of State’s partnership page and click the “Search” button.
Prospective business owners should also search trademarks, as a business owner might file a trademark for a trade name or trademark. To search for trademarks:
- Step 1: Navigate to the Illinois Secretary of State’s trademark search tool.
- Step 2: Under “Choose the Type of Search,” select the radio button for ‘Name of Mark.’
- Step 3: Under “Choose a Search Method,” select the radio button for ‘By Partial Name.’
- Step 4: Enter the search term in the search box.
- Step 5: Click the ‘Submit’ button.
If another business did not register the search terms, the system would show that the term was not found. If the system locates terms, it shows exact matches and similar terms. Business owners should check all of the search results to ensure that his business trademark is significantly different from other trademarks.
If a business owner wishes to register a trademark in Illinois, the registration protects the intellectual property only in the state of Illinois – not at the national level. If a business owner wishes to determine whether a business name or logo has been trademarked at the federal level, search the United States Patent and Trademark Office.
Before a business registers its name, the business owner should take additional steps to ensure that the name is available for domain and social media use. While the domain name and social media accounts or pages do not have to have the same name as the business, it is better for marketing purposes. If another person or entity is already using the name, a prospective business owner can choose another name to register at the state level or use a different name that describes the business for the domain name and social media accounts.
Check if the domain name is available
Most businesses today have an internet presence, if not for an online store, for marketing purposes. Prospective business owners can check domain registries such as GoDaddy to determine whether the chosen business name is available.
If a domain name is not available
Often a business name is unavailable because another individual or business from another state is using the name. In this case, the business owner has three choices:
- Pick a new business name if the business owner wants the domain name and business name to be the same. For example, if ABCWidgets.com is unavailable, do not choose ABCWidgets.net.
- Choose a similar name. However, don’t make it too similar, as that will confuse customers.
- Choose a descriptive name that describes the business’s products or services.
Check if the social media name is available
Business owners should also check social media platforms. Enter the business name into the search box on the platform. If the business comes up, another person is using the name. While the business owner could choose a very similar name, it is likely to confuse customers. Choose one of the options outlined for domain names.
How to register an Illinois business entity
Illinois allows prospective businesses to file online or via paper.
Each entity type has its own filling page.
Naming considerations for Illinois business entities
Each entity type also has its own naming conventions. When creating a new entity, choose the entity type. If you are not sure which entity type is best for your business, contact a business law attorney. Some entities are pass-through entities, which means the Internal Revenue Service taxes the individual business owner or partner, while others have double taxation, such as corporations.
Additionally, certain entities offer more personal protection than others. For example, if someone sues a sole proprietor, that business owner’s personal assets are not protected from the lawsuit. However, if someone sues a corporation, the plaintiff can only sue the business as long as the business owner did not comingle funds or take other actions to break the corporate veil.
Sole proprietorships and partnerships
Sole proprietorships and general partnerships might not have to register for anything, depending on whether they have employees or meet other requirements. If either uses a ‘doing business as’ or DBA name, they must register the name with the County Clerk.
Limited Liability Companies (LLCs)
A limited liability company must have one of the following in its name:
