Trademark Classes: How to Choose Goods and Services for Your Application

Jurisdiction: This guide covers U.S. federal trademark applications filed with the United States Patent and Trademark Office (USPTO), based on the legal framework applicable in October 2026. State trademark registrations and applications in other countries follow different requirements. International registrations designating the United States may also be subject to additional rules.

Choosing trademark classes begins with identifying the goods you sell or intend to sell and the services you provide or genuinely intend to provide. The United States uses the Nice Classification system, which organizes goods and services into 45 classes. But selecting a class number alone does not define the full scope of a trademark application.

This guide explains the 45-class framework, how to search the USPTO's official identification resources, and how a business with several activities can prepare a preliminary list of goods and services. It also explains important distinctions involving retail services, application filing bases, and changes to an identification after filing.

Trademark classes organize different types of goods and services for registration purposes. Classes 1 through 34 cover goods, while Classes 35 through 45 cover services.

The classification system provides a common starting point, but an applicant must identify the particular goods or services covered by the application. A registration in one class does not automatically cover every item in that class. Likewise, a difference in class numbers does not, by itself, establish that two trademarks cannot conflict.

The following table summarizes the general subject matter of all 45 classes. These are broad descriptions for orientation, not identification wording approved for a particular application. Consult the World Intellectual Property Organization's Nice Classification and the USPTO's current identification resources for the applicable classification details.

The classes appear side by side only to save space. Items in the same row are not legally connected, and the table should not be used to infer similarity between goods or services.

Start With the Goods and Services Your Business Actually Offers

A useful first step is to describe what customers receive from the business, rather than relying only on the industry name.

Instead of treating a brand name or logo as the starting point for class selection, distinguish the brand's visual identity from the particular goods and services it identifies. GenApe's trademark and logo guide explains that related branding distinction.

For example, a company may operate in the artificial intelligence industry while engaging in several distinct activities. It might distribute downloadable software, provide access to software through a website, create advertising materials for clients, and conduct paid training courses.

Those activities should not automatically be placed in one class merely because they all involve AI.

For each activity, record what is being offered, how customers receive it, and whether the activity is currently provided or genuinely planned. In a U.S. application, the filing basis matters: a use-based application under Section 1(a) has actual-use requirements, while a Section 1(b) application requires a bona fide intention to use the mark in commerce.

A speculative business idea should not be treated as interchangeable with a legally sufficient intent-to-use basis. For additional context about how identifying goods and services fits into the broader filing process, see GenApe's trademark registration guide. U.S. filing requirements should still be checked against USPTO guidance.

The USPTO's Trademark ID Manual helps applicants find goods and services descriptions that may be suitable for U.S. federal trademark applications. It is more useful than guessing a class from an industry label because it connects particular identification wording with classification information.

However, finding a term in the ID Manual is not the same as receiving approval of a trademark application. Classification, acceptable identification wording, filing basis, and registrability are separate questions.

Prepare a Specific List Before Searching

Begin by writing a plain-language description of each product or service.

Instead of entering only "AI business," describe the actual offering. For instance, identify whether customers download a software program, access a non-downloadable application online, purchase advertising services, or enroll in a course.

For software, details such as functionality, intended purpose, and how the software is provided may be important when choosing identification wording. For retail services, the relevant goods and the nature of the retail activity may need to be specified.

This preliminary inventory is a practical preparation method, not a legally prescribed four-step or five-step USPTO procedure.

Use the USPTO's Official Identification Resources

Start with the USPTO Trademark ID Manual and search for a concrete description of the goods or services.

When reviewing results, pay attention to the wording of the entry, its class, and any relevant explanatory information or restrictions. Similar everyday expressions may have different meanings when used in formal trademark identifications.

The USPTO's Trademark Manual of Examining Procedure (TMEP) provides additional guidance on identification requirements, classification, and amendments. Section 1402 is particularly relevant to the identification of goods and services.

The ID Manual is a reference for acceptable identification wording; it is not a database that determines whether a proposed trademark is available or whether a specific application will be registered.

Check the Wording, Class, and Relevant Notes

Once you find a promising entry, compare it with the activity you actually offer. A broadly related phrase may still be unsuitable if it describes a different product, service, delivery method, or purpose.

Do not assume that a description can be freely expanded after filing. Under 37 CFR § 2.71, amendments to the identification are subject to limits, including restrictions against broadening the original scope.

If you also need to assess whether another party may already be using a similar mark, that is a separate question from identification lookup. GenApe's trademark search overview provides background on that distinct stage; for U.S. federal records, consult the USPTO's official trademark search resources.

A business with several offerings should evaluate the goods and services associated with each activity rather than assume that one brand belongs in exactly one trademark class.

This distinction becomes particularly important for digital brands. A company may develop software, offer a hosted platform, deliver advertising services, and teach customers how to use its tools. These activities can share a brand identity without necessarily sharing the same trademark classification.

Consider a fictional AI content platform. It offers downloadable writing software, online access to an AI writing application, advertising copywriting for clients, and educational workshops.

When a brand is still developing its visual identity, tools such as the GenApe AI Logo Generator may help organize logo ideas alongside the brand's intended offerings. Logo creation, however, does not determine trademark classes, establish rights, or replace a trademark search.

The following example shows how to create preliminary classification candidates from the activities of a hypothetical AI company. It does not provide official identification wording for a real applicant.

These classes are illustrative starting points only. They are not an approved identification list, and an AI company is not automatically required to apply in all four classes.

The distinction between internal activity and customer-facing services is especially important. A business that uses AI software to write its own website content does not necessarily provide advertising services to others. Likewise, publishing instructions about a product does not automatically mean that the business operates a separate educational service.

A practical planning worksheet can help connect each potential class to a specific business activity and an appropriate next step.

This worksheet is a planning aid. It does not establish that any particular filing basis is satisfied, and it does not substitute for the applicant's actual goods and services identification.

For a growing brand, it may also help to distinguish what is currently offered from what is only under consideration. That distinction makes the subsequent USPTO review more focused and reduces the risk of treating every possible future business idea as an existing trademark use.

Before submitting a federal trademark application, review the relationship between the selected classes, the actual identification wording, and the applicable filing basis.

The following checklist combines legal filing considerations with optional preparation practices. Not every item is a separate statutory filing step.

• Identify the goods and services accurately. Confirm that each description reflects the actual offering rather than a vague business category.

• Check the relevant class and wording. Use the USPTO ID Manual and applicable guidance to review the proposed identification.

• Confirm the filing basis. Distinguish actual use in commerce from a bona fide intent to use, and consider any other applicable statutory basis.

• Separate products from retail services. Do not assume that selling your own goods automatically means you provide a separately registrable retail service.

• Review multi-activity coverage. Make sure the proposed list reflects the goods and services for which protection is actually sought.

• Consider trademark availability separately. Classification does not establish that the mark is available or registrable. Review the USPTO's official trademark search information where appropriate.

• Keep useful planning records. A working list of descriptions, candidate classes, and outstanding questions may help with preparation, although this particular worksheet format is not legally mandatory.

• Seek qualified advice where needed. Unclear descriptions, international filing routes, and amendment issues may require professional evaluation.

The USPTO's trademark application guidance provides the official starting point for federal filing requirements. The checklist above is limited to class selection and related preparation, not the entire trademark application procedure.

Are Products and Retail Services Covered by the Same Trademark Class?

Not automatically. Goods and retail services are different types of identifications. In U.S. practice, relevant retail store services are generally considered under Class 35, while the products themselves are classified according to their nature.

The identification of a retail service may need to describe the retail activity and the goods involved. Merely selling a company's own products does not necessarily establish a separate registrable retail service.

For further detail, see the USPTO's TMEP, particularly the guidance on identification of goods and services and retail services in Section 1402.11(a)(vi).

Different class numbers also do not conclusively determine whether goods and services are legally related for trademark-conflict purposes. That is a separate analysis.

Can You Change a Trademark Class After Filing?

Sometimes, but the answer depends on the filing basis, the original identification, and the procedural circumstances.

For certain applications filed under Section 1 or Section 44 of the Lanham Act, corrections to the description or classification may be possible if the original identification is not broadened and other applicable requirements are satisfied.

Applications based on an international registration under Section 66(a) are subject to different classification restrictions. Applicants should not assume that a class can be changed freely simply by paying another fee.

The applicable rules include 37 CFR § 2.71, 37 CFR § 2.85, and the relevant USPTO examination guidance.

If the original identification does not cover the additional goods or services, an ordinary amendment should not be assumed to provide a way to expand that scope.

What if the USPTO ID Manual Does Not List My Exact Goods or Services?

An exact match in the ID Manual is not always required. Applicants may be able to propose their own descriptions if the wording satisfies the USPTO's requirements for clarity, specificity, and accuracy.

Start by checking related entries and determining whether the proposed wording accurately identifies the offering. Software may require additional functional details, and retail services may require a clearer description of the activities and goods involved.

An unlisted description is not automatically prohibited, but a self-drafted identification is not automatically acceptable either. The USPTO may require clarification or amendment under the applicable rules.

Applicants should also consider the filing-fee implications of custom identification wording. For certain applications filed under Section 1 or Section 44, using the free-form text field instead of selecting an identification directly from the USPTO ID Manual in Trademark Center may result in an additional fee per class. Check the USPTO's current fee schedule before filing.

Trademark class selection becomes easier to manage when a business has a clear inventory of its products, services, delivery methods, and genuine expansion plans.

GenApe can be used as a content-planning aid while a team organizes brand descriptions, product information, and potential service offerings. These materials can support internal discussions about what to research in the USPTO ID Manual, but they do not replace official classification requirements or professional legal review.

For brands exploring additional visual identity concepts, the GenApe AI 3D Logo Generator is another creative tool to consider. Generating a logo does not establish trademark rights or guarantee registration.

Start with an accurate description of what your business actually provides. Then use the official USPTO resources to evaluate appropriate identifications and classes before filing.
