• Active – Entity is in good standing with current filings
• Dissolved – Entity has been formally dissolved or terminated
• Revoked – Entity lost good standing due to compliance failures
• Suspended – Temporary suspension pending compliance corrections
• Inactive – Entity exists but may not be conducting operations
• Foreign Authorized – Out-of-state entity authorized to operate in Maine

Specific Maine Rules for Business Naming and Restrictions

Maine's comprehensive naming regulations protect consumers and prevent marketplace confusion through statutory requirements and detailed restrictions. Understanding these rules before conducting your lookup prevents costly rejections and ensures business registration compliance from the start, saving time and filing fees during the formation process. Consider partnering with a Maine registered agent for expert LLC support and ongoing compliance.

Maine LLC and Corporation Name Requirements

Maine LLC names must include designators that clearly identify the entity type to the public and regulatory authorities. These requirements help distinguish limited liability companies from other structures and ensure proper legal recognition in commercial transactions, banking relationships, and professional service contracts.

Corporation naming follows similar but distinct requirements that emphasize corporate designation and public identification standards. Both entity types must maintain distinguishability from existing names while meeting statutory language requirements for their respective designators, ensuring compliance with Maine's comprehensive formation statutes and avoiding conflicts with existing registered entities.

Professional entities face naming requirements that reflect their licensed status. These specialized rules ensure that intellectual property protections and professional licensing standards remain clear to consumers and regulatory authorities.

For detailed statutory requirements, read the Maine Business Corporation Act which outlines naming provisions and compliance standards.

Distinguishability Rules and Restricted Words in Maine

Maine applies strict distinguishability standards that prevent consumer confusion between similar names in the marketplace. Business entities cannot adopt names that are identical or deceptively similar to existing registered names, regardless of minor variations in punctuation, spacing, or designators that don't create meaningful distinctions.

The state prohibits certain words and phrases that could mislead the public about an entity's nature, regulatory status, or professional capabilities. Common restricted terms include banking, insurance, and trust-related language unless the entity holds appropriate licenses or authorizations from relevant regulatory bodies, ensuring consumer protection and industry integrity.

Maine Guidelines for Using Assumed Names (DBAs)

Business names can operate under assumed names (also called “Doing Business As” or DBA names) when companies want to use names different from their legal entity names. Maine requires formal registration of assumed names through the Secretary of State to ensure proper public notice and compliance. Understand the differences in our post on DBA vs LLC to decide which approach fits your strategy.

The assumed name registration process involves these key steps:

• Verify assumed name availability through the corporate name lookup
• Complete Form ASUM-5 (Statement of Intention to do Business under an Assumed Name)
• Pay the $125 filing fee to the Bureau of Corporations
• Ensure the assumed name meets distinguishability requirements
• Submit the application with proper supporting documentation
• Maintain the registration through required renewals
• Update licenses and permits to reflect the assumed name

How to Reserve a Business Name in Maine (Step-by-Step Guide)

Strategic entrepreneurs often reserve their chosen name while finalizing formation documents and comprehensive plans. Maine business entity name reservations provide exclusive rights to use a name for 120 days, preventing competitors from claiming your preferred name during critical planning periods and development phases. Ensure you secure a physical location by checking how to get a business address for LLC options that suit your needs.

When Is a Name Reservation Necessary?

Name reservations become essential when entrepreneurs need time to complete complex formation requirements or secure necessary funding from investors or financial institutions. Business owner situations that typically benefit from reservations include securing investor commitments, finalizing partnership agreements, completing professional licensing requirements, or coordinating multi-state registrations.

However, many formations don't require reservations, particularly when entrepreneurs are ready to file formation documents immediately upon name verification. Simple LLC formations often proceed directly to filing since the name becomes officially reserved upon successful document submission, making advance reservations unnecessary for straightforward cases with clear plans and available funding.
