How to Find Your NAICS Code
Finding the right NAICS code is important for business registration, government forms, market research, business databases, compliance, and industry classification. A NAICS code identifies the primary economic activity of a business using a standardized industry classification system.
Follow these steps to find the most appropriate NAICS code for your business.
1. Describe Your Primary Business Activity
Start by identifying what your business primarily does. Focus on the activity that generates the majority of your company's revenue.
For example, a company may sell products online, provide consulting services, manufacture goods, or operate a restaurant. Your NAICS classification should generally reflect the business's primary activity rather than every service or product it offers.
Ask yourself:
- What products or services does my business primarily provide?
- What activity generates most of my revenue?
- Is my business involved in manufacturing, retail, wholesale, construction, healthcare, technology, or another industry?
- What is the main purpose of the business?
A clear description of your primary business activity makes it easier to perform an accurate NAICS code search.
2. Search by Industry Keyword
Use relevant keywords related to your business or industry to begin your NAICS code search.
For example, you might search for terms such as:
- Restaurant
- Software development
- Real estate
- Construction
- Accounting
- Online retail
- Trucking
- Marketing
- Healthcare
- Manufacturing
A keyword search can help identify industry classifications that are closely related to your business activity.
3. Review Matching NAICS Classifications
After searching, review the available NAICS classifications carefully. Multiple codes may appear relevant because many industries include similar or related business activities.
Read the descriptions associated with each classification and determine which one most accurately represents your primary operations.
It is important not to select a code based only on a keyword match. The full industry description should align with the actual products, services, and activities of your business.
4. Compare Available Codes
If several codes appear relevant, compare them side by side.
Look for differences in:
- Primary business activity
- Products or services offered
- Manufacturing versus retail activities
- Wholesale versus direct-to-consumer sales
- Specialized versus general services
- Industry-specific requirements
For example, a business that manufactures furniture may have a different NAICS classification than a business that sells furniture through a retail store.
Comparing available classifications helps reduce the risk of selecting an incorrect code.
5. Select the Most Appropriate Classification
Choose the NAICS code that most accurately represents your company's primary economic activity.
Businesses that perform multiple activities may need to identify which activity is considered their primary activity. In most cases, this is the activity responsible for the largest share of revenue or business operations.
If your business changes its primary products or services over time, it may also be necessary to review whether the existing NAICS classification is still appropriate.
A reliable NAICS code search tool can make this process easier by allowing users to search classifications by industry name, business activity, or code number.
Search NAICS Code by Business Industry
NAICS code search by business industry allows you to find industry classifications using keywords that describe your company's products, services, or primary activities.
Instead of knowing the exact numerical code in advance, you can enter an industry-related keyword and review relevant NAICS classifications.
For example, businesses can search using terms such as:
- Accounting services
- Computer programming
- Construction
- Restaurants
- Insurance
- Truck transportation
- Real estate
- Marketing services
- Manufacturing
- Retail stores
The search results can help identify classifications associated with the selected industry or business activity.
When performing a NAICS code search, use specific keywords whenever possible. For example, searching for "software development" may provide more relevant results than searching for the broader term "technology."
Businesses should also review the complete description of each result before selecting a classification. Similar industries may have different NAICS codes depending on the specific services provided or the way the business operates.
Searching by business industry is particularly useful for:
- New businesses selecting an industry classification
- Companies updating business information
- Researchers analyzing industries
- Marketers building industry-specific prospect lists
- Businesses completing government or regulatory forms
- Professionals organizing business database records
A NAICS code search by industry can help users quickly narrow down classifications without manually reviewing large numbers of industry codes.
Search NAICS Code by Number
If you already know all or part of a NAICS code, you can search directly by number.
NAICS codes are organized using a hierarchical numbering system. Depending on the level of classification, a code can represent a broad economic sector or a highly specific industry.
Searching by NAICS number is useful when you need to:
- Verify an existing NAICS code
- Confirm an industry description
- Find related classifications
- Check whether a code matches a specific business activity
- Research businesses within a particular industry
For example, if you have a NAICS code listed on a company profile, business database, government form, or registration document, you can search the number to view the corresponding industry classification.
You can also compare similar codes to understand how specific industries are grouped within broader sectors.
A NAICS number lookup can be especially helpful when working with business data, market research, lead generation, industry analysis, and company classification.

These examples demonstrate that businesses operating in similar sectors may still have different NAICS codes depending on their specific business model and primary activities.
For instance, a restaurant that provides full table service may have a different classification from a business focused primarily on fast or limited-service food. Similarly, a company that develops custom software for clients may be classified differently from a business that publishes packaged software products.
When using a NAICS code search tool, always compare the official industry description with your actual business activity before selecting a code. The most appropriate classification should reflect what your business primarily does rather than simply matching a general industry keyword.
If your business provides multiple products or services, identifying the primary revenue-generating activity can help you choose the most relevant NAICS code.
