A shampoo bottle and a salon sign can carry the same name without representing the same kind of offering. This trademark classes guide explains how the United States Patent and Trademark Office (USPTO) organizes goods and services, and why a class number alone does not define trademark protection.
34 classes
Categories for goods
Classes 1 through 34
11 classes
Categories for services
Classes 35 through 45

Source information checked against USPTO public guidance in November 2026. This overview explains general concepts. It does not determine which classes, descriptions, filing basis, or evidence are appropriate for a particular business.
What does this trademark classes guide explain?
Trademark classes are administrative categories used in applications, fee calculations, and trademark research. They help organize information, but they do not replace the legal analysis of a brand or its offerings.
The distinction matters to founders because a business can have one public identity and several different activities. A hypothetical creator might sell clothing and provide entertainment. Customers may recognize one name, while the trademark system distinguishes the goods from the services.
Understanding that distinction makes attorney conversations easier. It is different from deciding what an application should claim, which requires attention to the business facts and applicable requirements.
What are goods and services under USPTO guidance?
Goods are products customers purchase. Services are activities performed for the benefit of someone other than the business itself, according to the USPTO's goods and services guidance.
The USPTO uses bicycles and candles as examples of goods, and bicycle repair and catering as examples of services. An application can include both goods and services, but they are not placed together in the same international class.
For a hypothetical candle company, the candle is a product. A workshop the company provides is a different kind of activity. That example illustrates the goods-and-services distinction; it is not a recommendation about the company's application.
The difference does not depend on how polished a website looks or whether everything is sold from one checkout page. It concerns what the business provides under the trademark.
How many international trademark classes are there?
There are 45 international trademark classes: 34 classes for goods and 11 classes for services. Classes 1 through 34 organize goods, while Classes 35 through 45 organize services.
The USPTO explains that the categories are established by international agreement. Their numbers provide a shared organizational system, not a ranking of how valuable or protective a registration is.
Class 3 is not stronger than Class 25. A class number also does not describe how large the business is, how much revenue it earns, or how widely customers recognize the name.
These numbers often appear in public trademark records. Seeing several classes in another company's registration tells a reader that several categories are involved, not that the company owns its name for every possible business activity.
Why is a class heading different from an identification?
A class heading describes a broad category. An identification is the wording in an application that states the particular goods or services claimed.
The USPTO requires descriptions that are clear, accurate, and understandable. A general heading cannot, by itself, explain every product or service within a business.
Class 25, for example, concerns clothing. The fact that a registration identifies an item in Class 25 does not mean it lists every item of clothing within that category.
Think of the class as a filing drawer and the identification as the description of what is inside. The drawer organizes the record. The description supplies information the number cannot communicate.
The analogy has limits: the legal scope of rights is not decided by a drawer label or a single sentence from an article. Applying the rules to a specific registration is an attorney's task.
What do familiar class headings tell a business owner?
Class headings offer a general orientation to the USPTO system. The examples below reproduce selected broad categories from the agency's public overview, not application-ready descriptions.
International class
Broad category in the USPTO overview
Educational distinction
3
Cosmetics and cleaning preparations
A goods category, not a general category for every beauty business
16
Paper goods and printed matter
A goods category rather than a description of every publishing activity
25
Clothing
The category does not identify every garment in an application
35
Advertising and business
A service category, not blanket coverage for everything a business sells
41
Education and entertainment
A service category rather than a category for every creator's merchandise
42
Computer and scientific
A service category distinct from categories containing goods
44
Medical, beauty and agricultural
A service category distinct from cosmetics sold as products
These headings are useful for recognizing terminology in public records. They are too general to function as a class-selection checklist.
A category that sounds close to a business's marketing language does not establish that the business belongs there. Classification depends on the actual offering and applicable USPTO requirements.
Why can a beauty brand involve different categories?
Beauty products and beauty services are different types of offerings. The USPTO overview places cosmetics in Class 3 and beauty services within Class 44.
Consider a hypothetical founder whose company sells shampoo and also operates a salon. The example shows why the phrase beauty brand does not fully describe the business for trademark purposes.
It does not establish what that founder should include in an application. Product details, the services actually provided, and how the name is used all matter to an individual assessment.
A short online class list cannot resolve those facts. The educational takeaway is the distinction between a product and a service, not a direction to file in either or both classes.
Why does an online business still need a specific description?
Online describes a delivery or sales channel, not necessarily the goods or services themselves. The USPTO system still distinguishes different offerings available through that channel.
A hypothetical creator might have a website containing merchandise, entertainment, and software access. The shared website does not turn those activities into one interchangeable category.
The USPTO's identification resources distinguish recorded or downloadable software, online non-downloadable software, publications, and retail store services. Those distinctions illustrate why broad labels such as digital business leave important facts unstated.
This article does not supply wording for any of those offerings. Its purpose is to explain why the everyday description of a business and its legal identification are not always the same thing.
What is the Trademark ID Manual?
The Trademark ID Manual is the USPTO's searchable list of identifications that are properly classified under the current international classification system. It is a reference resource, not a personalized assessment of a business.
The agency's Trademark Identification Manual guidance explains that entries must meet requirements for clarity, accuracy, and specificity. Some entries contain portions requiring additional information.
An accepted entry shows that wording can meet identification requirements in an appropriate situation. It does not establish that the wording accurately describes a particular applicant's business or that the trademark will be approved.
The USPTO also states that its staff cannot advise which identification describes an applicant's goods or services or draft an identification for that applicant. That boundary is useful: understanding the resource is public education; choosing and tailoring a legal claim requires individual analysis.
How do class counts relate to government fees?
The USPTO charges application fees by international class, subject to the applicable application requirements. Several offerings within one class and offerings spread across several classes can therefore produce different government costs.
Class count is not the entire fee picture. The USPTO's public guidance also explains that identification choices can involve additional charges.
Government fees are separate from a law firm's service fees. A firm's quoted service price should not be read as a statement that all government charges or later work are included.
This overview does not calculate a reader's filing costs or suggest reducing class count to reach a particular budget. The appropriate scope and current charges belong in an individual attorney discussion before a filing decision.
Do different classes eliminate conflicts between names?
No. Different class numbers do not guarantee that similar trademarks can coexist without a conflict.
The USPTO's explanation of possible grounds for refusal identifies similarity between marks and the commercial relationship between their goods or services as principal considerations in likelihood of confusion. That term describes the risk that consumers will mistakenly believe the offerings come from the same source.
The agency gives clothing and online retail store services featuring clothing as an example of related goods and services. The point is that a product and a service can be commercially related even though they are different types of offerings.
A class number is therefore not a permission slip to adopt a similar name. It also does not resolve the meaning of another business's registration or whether a particular use infringes someone's rights.
How is classification different from a clearance search?
Classification organizes goods and services. A clearance search investigates potential naming conflicts; an attorney assesses what the findings mean for the business.
A reader can recognize a familiar category in a trademark record without being able to evaluate the legal significance of that record. Similar wording, related offerings, and the surrounding facts can matter in ways that class numbers do not show.
BrandProtector.com's trademark clearance search guide introduces that separate subject. Reading a search guide or a classification overview does not establish that a name is available.
Likewise, a classification match is not an approval prediction. The USPTO considers grounds for refusal beyond whether goods and services are assigned to the correct category.
Why do current offerings and future plans matter?
The USPTO distinguishes applications based on use in commerce from those based on a bona fide intent to use. In general terms, these concern existing qualifying use and a genuine intention to use the trademark, respectively.
Its goods-and-services guidance states that the applicable requirement concerns all listed goods and services. That explains why a company's launched products and future plans are not interchangeable facts.
This overview does not determine whether a business meets either standard, which basis it should choose, or what evidence would support a claim. It also does not recommend phased applications or other filing strategies.
Those are individual legal questions. An attorney needs the actual business history, not an assumption that a founder's long-term ambitions are the same as existing use.
What can business owners gather before speaking with counsel?
Existing business records can help an attorney understand what the company does. Gathering those records is administrative preparation, not a substitute for evaluating legal requirements.
Useful materials can include:
Current product lists and service descriptions.
Existing website pages, packaging, and labels.
Business records showing when offerings launched.
Existing plans for offerings that have not launched.
Copies of applications, registrations, or USPTO correspondence already received.
These materials provide context. Their inclusion in an attorney's file does not mean they satisfy USPTO evidence requirements.
There is no need to turn this preparation into drafting legal descriptions or deciding how to answer an examiner. Questions about application wording, amendments, evidence, or a refusal belong with counsel reviewing the actual record.
When is individual attorney help important?
Individual help matters when a general concept becomes a decision about a particular name, application, or registration. A public article cannot determine the right coverage for an unseen business.
Examples include uncertainty about which offerings a filing should include, similar names appearing in search results, or an existing USPTO notice raising identification issues. These involve more than recognizing a class heading.

Frequently asked questions
Does one trademark class cover every item in that category?
No. A class is an organizational category, while an application's identification names particular goods or services. The number alone does not establish the full legal scope of protection.
Can goods and services appear in the same international class?
No. The USPTO separates goods and services into different international classes. An application can contain both types of offerings across the appropriate categories.
Do different classes mean similar business names cannot conflict?
No. The USPTO considers the similarity of marks and the commercial relationship between their goods or services. Different class numbers do not decide that analysis.
Does an ID Manual entry guarantee trademark approval?
No. An entry concerns identification wording and classification, not approval of a particular trademark. The wording must also accurately describe the applicant's actual offering.
Does an online store's class cover every product it sells?
No. Retail services and the goods sold through a store are distinct concepts. A class number does not grant blanket protection for every item on a website.
Can this guide tell me which classes to file in?
No. This guide explains the USPTO system for general education. Decisions about classes, application wording, filing basis, and evidence require an assessment of the particular business and legal requirements.
What is the main point to remember?
A trademark class tells you where an offering is organized, not everything about the rights attached to a name. Understanding that limit helps business owners recognize why legal review involves more than matching a product to a number.
