What is an Entity Name? Legal vs. DBA and Trade Names

The entity name is the official identifier for a business or organization, establishing it as a legal person separate from its owners. This name is required for all government filings and serves as the formal foundation for the company’s legal and financial responsibilities. Understanding the difference between this legal designation and names used for marketing is crucial for compliance and brand protection.

Defining the Legal Entity Name

The legal entity name is the formal designation registered with the state authority, typically the Secretary of State, when the company is formed. This name officially establishes the business as a recognized legal structure, such as a Limited Liability Company (LLC) or a Corporation. It appears on formation documents, including the Articles of Organization or Articles of Incorporation, and functions as the company’s official signature.

The legal name establishes the company’s identity for all governmental and contractual purposes. A business must use this name when entering contracts, applying for loans, opening bank accounts, and filing tax returns using its Employer Identification Number (EIN). For structures offering liability protection (LLC or Corporation), consistent use of the legal name reinforces the separation between business finances and the owners’ personal assets.

Entity Name Requirements and Restrictions

State authorities mandate that a chosen entity name must be distinguishable from all other entities already on record within that jurisdiction. This “distinguishability standard” means the name cannot be deceptively similar to an existing one. Minor differences like punctuation, articles (a, an, the), or organizational suffixes are usually not considered sufficient to qualify as unique.

States also restrict the use of certain words and phrases within a legal entity name. Words implying a highly regulated industry, such as “Bank,” “Trust,” or “Insurance,” are restricted and may require special licensing or approval. Names that falsely suggest governmental affiliation, using terms like “Federal,” “Treasury,” or “Agency,” are generally prohibited to prevent misleading the public.

How Entity Names Differ by Business Structure

The choice of business structure dictates the naming conventions incorporated into the legal entity name. The most visible difference is the mandatory inclusion of a specific organizational suffix, which communicates the business’s legal status. These suffixes are required for liability-shielding entities, serving as public notice of their limited liability status.

A Corporation is legally required to include a word or abbreviation signifying its corporate status, such as “Incorporated,” “Corporation,” or “Inc.” Limited Liability Companies must similarly include “Limited Liability Company” or the common abbreviation “LLC.” The inclusion of these terms ensures that parties contracting with the business are aware of the structural limitations on the owners’ liability.

Sole Proprietorships and General Partnerships do not create a separate legal entity and lack a mandatory organizational suffix. The legal name of a Sole Proprietorship is the owner’s full personal name, and a General Partnership uses the full names of all partners. If these unincorporated businesses operate under a name other than the owners’ personal names, they must register a separate operating name, often called a Doing Business As (DBA) or Fictitious Name.

Distinguishing Entity Names from Other Business Names

Doing Business As (DBA) or Fictitious Name

A Doing Business As (DBA), also known as an assumed or fictitious name, is a secondary operating name different from the official legal entity name. It allows a corporation to market a specific product line or a sole proprietor to use a professional name without forming a new legal entity. DBA registration is conducted at the state or county level and serves purely as a public notice requirement. Unlike the legal entity name, a DBA does not create a new legal structure or provide liability protection.

Trade Name or Brand Name

The trade name, or brand name, is the public-facing identity used in advertising, marketing, and communication with customers. This name builds recognition in the marketplace and may or may not align with the legal entity name or a registered DBA. Its purpose is commercial distinction and consumer appeal rather than legal compliance.

Trademark

A trademark is intellectual property that protects a brand name, logo, or slogan used on goods or services in commerce. Registering a legal entity name only guarantees uniqueness among registered entities within that state, providing no nationwide protection. Federal trademark registration with the USPTO is necessary to protect the name as a source identifier across all states and industries. The scope of a trademark focuses on preventing consumer confusion in the marketplace, which is broader than the administrative uniqueness checked during entity registration.

Domain Name

A domain name is the address used to locate a company’s website on the internet. Registering a domain name secures an internet address through a domain registrar but confers no legal status or official business identity. Ownership of a domain name does not grant the holder rights to use that name as a legal entity or a protected trademark. It is an administrative necessity for an online presence but does not substitute for formal entity formation or brand protection.

The Process of Entity Name Selection and Registration

Securing a legal entity name begins with a thorough name availability search on the state’s official database, typically maintained by the Secretary of State’s office. This search confirms that the proposed name is distinguishable from all pre-existing names of corporations and LLCs on file. After confirming availability, a business owner may file a name reservation request with the state for a fee.

A name reservation temporarily holds the name for the applicant, usually for 60 to 120 days, preventing others from claiming it. This is useful if the owner needs time to finalize other formation details before submitting official paperwork. The final registration occurs when the business files its formation documents, such as the Articles of Incorporation, which officially establishes the legal entity and secures the name permanently.

Ongoing Compliance and Name Changes

Maintaining compliance requires the legal entity name to be consistently used on all official business documents, reinforcing the separation between the business and the owners. The legal name must be used on all tax forms filed with the IRS and is required by banks to open and maintain a business checking account. Failure to use the legal name for financial and contractual purposes risks “piercing the corporate veil,” potentially exposing the owners to personal liability for business debts.

Should a business formally change its legal name, it must file an amendment document with the state where the entity was formed. This document is typically called an “Articles of Amendment” (for corporations) or a “Certificate of Amendment” (for LLCs). The new name must first pass the state’s distinguishability test before the amendment is approved. Once approved, the company must notify relevant parties, including the IRS and financial institutions, to update all official records.
