The most effective way to look up an LLC in Idaho is to search the business by name.

This will help ensure that no other existing entity possesses the name. Otherwise, it would be rejected by the Idaho Secretary of State, extending the processing period of your LLC.

a. Searching by Business Name

Enter the LLC name you want to search 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 contains many words, you may limit your Search to the first two words to guarantee that you find all potential comparable names.

"Utilizing digits (such as 5 or 101) rather than writing numbers in words ("five" or "one hundred and one") does not make a name unique, nor does the use of Roman numerals (like "II" instead of 2, or "MMXII" instead of 2012) add to its distinctiveness."
