Business name availability
Even if none of the names you search return any results, the name could still be registered as a trademark.
In order to determine whether or not you can still register a specific name, search the Illinois Trademark Database.
In the event the name you were considering is taken, you may need to go back to the drawing board and spark your creativity. However, the business search is a good place to look for inspiration.
Even if the name you want is taken, you can still use the results to think of variations of the name as long as the name you’re going to register is unique and distinguishable from any other registered business in Illinois. This rule applies to reserved names as well.
You must not use words or terms that imply that your company is affiliated with any banking, insurance, or fiduciary company unless you have authorization from the state Commissioner of Banks and Real Estate.
Do not include words that suggest your company is affiliated with a government agency like Treasury, FBI, or State Department.
You may conduct business under your legal entity name only unless you’ve registered a DBA.
In the event a business name is available, but you are not ready to complete the registration process, you should consider a name reservation.
To reserve a name in Illinois, complete the Application to Reserve a Name Form.
The form requires the following information:
- Name to be reserved
- Title and signature of the applicant
- Name and address of the applicant
After completing the form, you may send two copies via mail to:
Secretary of State Department of Business Services Limited Liability Division
501 S. Second St., Rm. 351
Springfield, IL 62756
You will also need to pay a filing fee of $25 to the Secretary of State for the name reservation.
Domain name availability
After checking the availability of your preferred legal entity name, it’s time to start thinking about a domain name as well. Domain names are more relevant now than ever before, and they are priceless when it comes to establishing your business’s brand and online presence.
Essentially, a domain is a great marketing tool, especially when it comes to pointing people in the direction of your products and services. So is imperative that every business have a domain name to establish their online presence in the age of the Internet.
The challenge begins with securing an available domain name. With millions of websites coming to the forefront each and every day, it’s becoming harder to find an available domain name.
This is why you should use a professional domain checking service like namechk.com. The service is highly recommended since it is professional and helps in a number of ways. For one, namechk.com is helpful when it comes to filtering results and offering suggestions and alternatives in the event that your desired domain name is already in use by another business.
It is advisable that once you come across a domain name that is available, you immediately register it to avoid it being scooped up by another business entity.
Fictitious business name search
The next part of the process is considering registering a DBA. Irrespective of whether you are a sole proprietor that’s come up with a catchy business name or you want to new alias for your limited liability company; you’ll still need to register DBA in Illinois.
Registering the DBA or fictitious name with the state ensures that you can legally transact within the state. The good news is that registering a DBA is affordable and simple.
The process of registering your fictitious name depends on your business structure. If you are forming a corporation or LLC, you can register your DBA with the Secretary of State’s office.
Additionally, when registering a fictitious name in Illinois, it must be distinguishable from existing names in the state. So before completing the application, check that the desired name is indeed available by conducting a business search on the Secretary of State’s website.
The fictitious name registration can be completed online by filling in the relevant form and submitting it either in person or by mail. The assumed name is effective from the date of filing and expires on the first day of the anniversary month from the filing date.
It costs $150 for a DBA registration that is valid for five years.
