When starting a business entity in Idaho, it's important to make sure all your legal bases are covered. One of the first stages in forming your LLC is to look for and confirm the availability of your selected LLC name.
With over a decade of practice as a business consultant for LLCs and thorough research on the steps to look up a business entity in various states, I’ll provide you with a comprehensive guide backed with all the legal information you need.
Quick Summary
- To look up an LLC in Idaho, go to the Idaho Secretary of State website and use the business entity search bar.

How Do I Look Up an LLC in Idaho?

To look up an LLC in Idaho, the most effective way is to search the business by name.
This will help ensure that no other existing entity possesses the title. Otherwise, it would be rejected by the Idaho Secretary of State, extending the processing period of your LLC.
The most effective way to look up an LLC is by visiting the Secretary of State's official website. The steps include the following:
Step 1: Check the Idaho Entity Name Database
On the Secretary of State's website, there is an updated database of business entity names, where you can check the availability of your desired business name for free.
Step 2: Do a Search for your Business Name
Enter the LLC name you want to use and remove identifiers such as "LLC," then click Search. Capitalization doesn't matter. This will display all entities that have the same or similar names.
If your business name consists of many words, you may limit your search to the first two words to guarantee that you find all potential comparable names.
Step 3: Review Results

Review the list of business entities in Idaho.
Use this guide to look up for an LLC and determine whether your preferred LLC name is available or not:
- If the business entity search returns no results, your selected entity name is free to use.
- If the results indicate no similarity, your selected LLC name is distinct from others and is eligible for use.
- If the business entity search returns exactly as it is, then it means that your desired LLC name is already taken. Therefore, you must come up with a new LLC name or a unique variation of your preferred business entity name.
- If the list indicates deceptively similar name results, then your desired LLC name can't be used.
However, even if the name of the business you desire is available, the Secretary of State will make a final assessment at the time of filing to verify that the name you choose isn't too similar to other registered business entities.
You can change your LLC name in Idaho at any time if you need to.
Idaho Search Options

Idaho search options include a business entity search by "Name" or by "Filing Number."
The Idaho Secretary of State's website has a database of all registered LLCs in the state.
There are several ways you may use to conduct a thorough company name search, including:
- Search by Business Name
- Search by Registered Agent
- Search by File Number
- Search by Filing Date
Another search option to consider is "Trademark Search." You must be cautious that your Idaho business name does not violate the trademark of another company.
Even though the desired Idaho business name is confirmed to be available on the state website, it may be protected by a registered trademark.
Therefore, it is recommended to do a trademark search using the Trademark Electronic Search System before deciding on a business name to avoid any legal issues in the future.
Information for Idaho LLC Look Up
Aside from the availability of the name, the database on the state's website also provides the following business information for an Idaho LLC:
- Filing Type: Identifies whether the business entity type is Corporation, Limited Liability Company, etc.
- Status: A business with an "active-existing" status indicates that the name has been taken. An inactive entity may not be conducting business presently but is still registered. A dissolved entity is no longer registered with the state, and the name is made available after four months [1].
- Term of Duration: Determines how long the company entity will be in operation. Idaho businesses tend to operate indefinitely.
- Principal Address: It's not specified, but the principal address may either be the actual mailing address of the business or a location where business documents are kept.
- Registered Agent's Information: If a legal or tax notification has to be delivered to the business, the Registered Agent is the person to contact. Many LLC owners would instead hire a registered agent service in the state of Idaho.
- Initial Filing Date: Refers to the date the business entity was filed with the Secretary of State.
