Maine Business Name Availability


These are the basics of searching for a business name in Maine.  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 found on the Maine business entity database?

A Maine business search can find several pieces of information about the businesses in the state. Some of the highlights include:

  • Legal Name
  • Filing Type: Corporation, Limited Liability Company. Etc.
  • Status: Good standing means all reports and filing fees are up to date. Suspended means the business may not be in operation. In some cases, the name of a suspended business may be available to register.
  • Filing Date: The date the entity was filed with the Secretary of State
  • Registered Agent Information: Maine 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 listed.  
  • Officer Names: 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.
