Trade name

Last updated

A trade name, trading name, or business name is a pseudonym used by companies that do not operate under their registered company name. The term for this type of alternative name is a "fictitious" business name. [1] Registering the fictitious name with a relevant government body is often required.


In a number of countries, the phrase "trading as" (abbreviated to t/a) is used to designate a trade name. In the United States, the phrase "doing business as" (abbreviated to DBA, dba, d.b.a., or d/b/a) is used, [1] [2] among others, such as assumed business name [3] or fictitious business name. [4] In Canada, "operating as" (abbreviated to o/a) and "trading as" are used, although "doing business as" is also sometimes used. [5]

A company typically uses a trade name to conduct business using a simpler name rather than using their formal and often lengthier name. Trade names are also used when a preferred name cannot be registered, often because it may already be registered or is too similar to a name that is already registered.

Using one (or more) fictitious business name(s) does not create one (or more) separate legal entities. [2] The distinction between a registered legal name and a fictitious business name, or trade name, is important because fictitious business names do not always identify the entity that is legally responsible.

Legal agreements (such as contracts) are normally made using the registered legal name of the business. If a corporation fails to consistently adhere to such important legal formalities like using its registered legal name in contracts, it may be subject to piercing of the corporate veil. [6]

In English, trade names are generally treated as proper nouns. [7]

By country


In Argentina, a trade name is known as a nombre de fantasía ('fantasy' or 'fiction' name), and the legal name of business is called a razón social (social name).


In Brazil, a trade name is known as a nome fantasia ('fantasy' or 'fiction' name), and the legal name of business is called razão social (social name).


In some Canadian jurisdictions, such as Ontario, when a businessperson writes a trade name on a contract, invoice, or cheque, he or she must also add the legal name of the business. [8]

Numbered companies will very often operate as something other than their legal name, which is unrecognizable to the public.


In Chile, a trade name is known as a nombre de fantasía ('fantasy' or 'fiction' name), and the legal name of business is called a razón social (social name).


In Ireland businesses are legally required to register business names where these differ from the surname(s) of the sole trader or partners, or the legal name of a company. The Companies Registration Office publishes a searchable register of such business names. [9]


In Japan, the word yagō (屋号) is used.



In Colonial Nigeria, certain tribes had members that used a variety of trading names to conduct business with the Europeans. Two famous examples were King Perekule VII of Bonny, who was known as Captain Pepple in trade matters, and King Jubo Jubogha of Opobo, who bore the pseudonym Captain Jaja. Both Pepple and Jaja would bequeath their trade names to their royal descendants as official surnames upon their deaths.


In Singapore, there is no filing requirement for a "trading as" name, but there are requirements for disclosure of the underlying business or company's registered name and unique entity number. [10]

United Kingdom

In the United Kingdom, there is no filing requirement for a "business name", defined as "any name under which someone carries on business" that, for a company or limited liability partnership, "is not its registered name", but there are requirements for disclosure of the owner's true name and some restrictions on the use of certain names. [11]

United States

A minority of U.S. states, including Washington, still use the term trade name to refer to "doing business as" (DBA) names. [12] In most U.S. states now, however, DBAs are officially referred to using other terms. Almost half of the states, including New York and Oregon, use the term Assumed Business Name or Assumed Name; [13] [14] nearly as many, including Pennsylvania, use the term Fictitious Name. [15]

For consumer protection purposes, many U.S. jurisdictions require businesses operating with fictitious names to file a DBA statement, though names including the first and last name of the owner may be accepted. [16] This also reduces the possibility of two local businesses operating under the same name, although some jurisdictions do not provide exclusivity for a name, or may allow more than one party to register the same name. Note, though, that this is not a substitute for filing a trademark application. A DBA filing carries no legal weight in establishing trademark rights. [17] In the U.S., trademark rights are acquired by use in commerce, but there can be substantial benefits to filing a trademark application. [18] Sole proprietors are the most common users of DBAs. Sole proprietors are individual business owners who run their businesses themselves. Since most people in these circumstances use a business name other than their own name,[ citation needed ] it is often necessary for them to get DBAs.

Generally, a DBA must be registered with a local or state government, or both, depending on the jurisdiction. For example, California, Texas and Virginia require a DBA to be registered with each county (or independent city in the case of Virginia) where the owner does business. Maryland and Colorado have DBAs registered with a state agency. Virginia also requires corporations and LLCs to file a copy of their registration with the county or city to be registered with the State Corporation Commission.

DBA statements are often used in conjunction with a franchise. The franchisee will have a legal name under which it may sue and be sued, but will conduct business under the franchiser's brand name (which the public would recognize). A typical real-world example can be found in a well-known pricing mistake case, Donovan v. RRL Corp., 26 Cal. 4th 261 (2001), where the named defendant, RRL Corporation, was a Lexus car dealership doing business as "Lexus of Westminster", but remaining a separate legal entity from Lexus, a division of Toyota Motor Sales, U.S.A., Inc.

In California, filing a DBA statement also requires that a notice of the fictitious name be published in local newspapers for some set period of time to inform the public of the owner's intent to operate under an assumed name. The intention of the law is to protect the public from fraud, by compelling the business owner to first file or register his fictitious business name with the county clerk, and then making a further public record of it by publishing it in a newspaper. [19] Several other states, such as Illinois, require print notices as well. [20]


In Uruguay, a trade name is known as a nombre fantasía, and the legal name of business is called a razón social.

In most cases, trademark dilution involves an unauthorized use of another's trademark on products that do not compete with, and have little connection with, those of the trademark owner. For example, a famous trademark used by one company to refer to hair care products might be diluted if another company began using a similar mark to refer to breakfast cereals or spark plugs.

Canadian trademark law provides protection to marks by statute under the Trademarks Act and also at common law. Trademark law provides protection for distinctive marks, certification marks, distinguishing guises, and proposed marks against those who appropriate the goodwill of the mark or create confusion between different vendors' goods or services. A mark can be protected either as a registered trademark under the Act or can alternately be protected by a common law action in passing off.

A legal name is the name that identifies a person for legal, administrative and other official purposes. A person's legal birth name generally is the name of the person that was given for the purpose of registration of the birth and which then appears on a birth certificate, but may change subsequently. Most jurisdictions require the use of a legal name for all legal and administrative purposes, and some jurisdictions permit or require a name change to be recorded at marriage. The legal name may need to be used on various government issued documents. The term is also used when an individual changes their name, typically after reaching a certain legal age.

Trademark distinctiveness is an important concept in the law governing trademarks and service marks. A trademark may be eligible for registration, or registrable, if it performs the essential trademark function, and has distinctive character. Registrability can be understood as a continuum, with "inherently distinctive" marks at one end, "generic" and "descriptive" marks with no distinctive character at the other end, and "suggestive" and "arbitrary" marks lying between these two points. "Descriptive" marks must acquire distinctiveness through secondary meaning—consumers have come to recognize the mark as a source indicator—to be protectable. "Generic" terms are used to refer to the product or service itself and cannot be used as trademarks.
