Ohio Naming Requirements

Some key guidelines for Ohio LLC names include:

  • Your name must include the phrase “limited liability company” or one of the following: LLC, L.L.C., limited, ltd., or ltd. 
  • Your name must be distinguishable from any existing business in the state. This includes Ohio reserved names.

Keep an eye out for restricted words. These words, such as “FBI” or “Treasury,” are often restricted to keep your LLC from sounding like an official institution.

Ohio also has the following restrictions for LLC names:

  • Your name cannot contain profanity or words or phrases that are generally considered a slur against an ethnic group, religion, gender, or heredity.
  • Your name cannot incorrectly or improperly imply that the business is affiliated with a government agency.
  • Your name cannot include any of the following words without prior approval from the superintendent of financial institutions: bank, banker, banking, trust, or words of similar meaning in any other language.
  • Your name cannot include the following unless the LLC is registered as a cooperative: cooperative, coop, co-operative, or co-op.

For more information, check out Ohio’s official state statutes.


It is important that your name be distinguishable from all other business names. In Ohio, a distinguishable name is one that is substantively different from all other existing or reserved business names in the state.

The following differences will make a name distinguishable in Ohio:

  • The use of numbers in a name, including using numerals versus spelled out numbers
  • Addition of letters
  • Different order of words
  • Spelling variations
  • Different forms of base words

The following differences do NOT make a name distinguishable in Ohio:

  • Use of punctuation, contractions, or abbreviations
  • Use of articles
  • Business entity type designators
  • Different tenses or singular/plural forms of the same word

Failure to use a distinguishable name could result in your formation filing being rejected.
