Montana Business Name Availability


These are the basics of searching for a business name in Montana.  Even when the name of the business you want is available, the Secretary of State will make a final determination at the time of filing to ensure the name you picked isn’t too similar to other registered names. 


What information can be looked up?

The database search can find several pieces of information about the business. Some of the highlights include:

  • Entity Name
  • Entity Status – Active Good Standing means all reports and filing fees are up to date. Other results include “Inactive Voluntary Dissolution, Inactive Revocation,” “Cancelled,” among others. The names of these results may be available to register.
  • Entity type – Corporation, Limited Liability Company. Etc.
  • Formation Date – Date the entity first became active
  • Registered Agent’s information – A Registered Agent is the singular point of contact for the entity should a legal, or tax notice need to be sent to the business.  This is often one of the owners, and if their home address is used, that address becomes public information.  Many people find this concerning and use a Registered Agent service like Northwest Registered Agent, so their home address isn’t publically listed.  
  • Date the entity was filed with the Secretary of State
  • Names of the officers and their title


Something to keep in mind is that even though each Corporation and LLC name must be unique, it may not stop someone else from using that name since business names for a sole proprietorship or partnership are not registered by the Secretary of State and are not required to be unique.  To protect your business name, consider getting a trademark.
