Idaho Corporation Name Requirements

Key Guidelines

Idaho has official requirements for its corporation names.

The name must contain one of the following words or abbreviations: corporation, incorporated, company, limited, Corp., Inc., Co., Ltd., or words or abbreviations of similar meaning in another language.

If the corporation is a professional entity, the name may contain the words "chartered," "professional association," or "professional corporation," the abbreviations "P.A.," "P.C.," or "CHTD," or words or abbreviations of similar meaning in another language.

There are also restricted words, such as “FBI” or “Treasury,” that you cannot use in order to keep your LLC from sounding like an official institution.

For more information, check out the Idaho state statute on corporation names.

Distinguishability

Your name must be distinguishable from all other Idaho business names. In Idaho, a distinguishable name is one that is substantively different from all other existing or reserved business names in the state.

Suffixes such as LLC and Corp. are NOT considered substantial differences.

If your corporation name isn’t distinguishable, your Articles of Incorporation filing will likely be rejected.
