If a business name is listed as “not available” or “not distinguishable,” that means your ideal business name is already on record with the Secretary of State. To see if a name is spoken for, search our database for a few key words.

We advise leaving out required terms and abbreviations and articles of speech to get the most accurate results. If you find a name similar to your entity’s you may want to seek legal counsel to ensure it will not put you in hot water.

To distinguish your entity name from those already in the system, you can:

– Add an article of speech such as “the” and “a”
– Add abbreviations such as “LLC”, “Corp”, and “Inc” to your entity name

Periods, underscores, and capitalized letters will not, however, make your name distinguishable.
