To find a company's NAICS code, search for the business and identify the specific establishment or location you want to classify. Review the NAICS code associated with that location, then confirm that the code matches the activity actually performed there and that the code belongs to the NAICS revision you need.
A company does not necessarily have one NAICS code that applies to every location or every use. For federal statistical classification, NAICS is establishment-oriented, so different locations within the same enterprise can be classified in different industries. Other agencies, contracting systems, and commercial databases may maintain NAICS information for their own purposes.

Search the public business name. SICCODE.com company search looks up the company name, not the city. After results appear, use the city, state, address, or branch shown on each record to confirm the establishment you need.
Make sure the business profile or record represents the location you actually want to research. A headquarters, plant, store, warehouse, and branch office can perform different activities.
Compare the code with the activity performed at that location. Open the 6-digit NAICS definition and review the description, examples, cross-references, and exclusions.
The current U.S. NAICS manual is the 2022 edition as of September 2026, but a specific agency, database, or historical record may use another revision. Follow the rules of the system where the code will be used.
The Census Bureau defines an establishment as generally a single physical location where economic activity occurs. An enterprise can own one or many establishments, and each establishment is classified according to its own primary activity for federal statistical purposes.
This is why searching only the brand name can be misleading. The first company record you find may describe a different location from the one you are researching.
Not in the sense of one code that is assigned once by a central authority and then controls every future use. Census guidance states that there is no central government agency responsible for assigning, monitoring, or approving NAICS codes for all establishments.
Different agencies maintain their own establishment lists for their own program needs and can use their own methods to assign NAICS codes. Commercial business databases also maintain classifications according to their own research methods, source data, and update processes.
A difference does not automatically mean one source is wrong. Several legitimate factors can produce different classifications.
NAICS is revised periodically. The current U.S. manual is the 2022 NAICS edition. A 2027 revision is under development as of September 2026, but it has not yet replaced the 2022 classification.
Code changes between editions are important when researching company records because an older code can still describe a historically correct classification while no longer being the current code number.
| Activity | 2017 NAICS | 2022 NAICS | What changed |
|---|---|---|---|
| Software Publishers | 511210 | 513210 | The industry remains Software Publishers, but the code moved within the 2022 Information sector structure. |
| Electronics and Appliance Retailers | Older retail records may contain 443142 and related 2017 classifications | 449210 | The 2022 retail structure was reorganized. Do not treat 443142 as a one-to-one rename of 449210. |
When a company profile displays an older NAICS code, use a current Census concordance or the current industry definition before treating that number as the company's present-day classification.
After finding a code in a company profile or database, compare it with the current industry definition. This is especially useful when the company has several business lines or the classification will be used for research, targeting, underwriting, procurement, or compliance.
Search the company name first. Company search does not filter by city. Large companies, franchises, healthcare systems, retailers, manufacturers, and multi-location service businesses can have many establishments with similar or identical names, so use the location details on each result to identify the right record.
Useful disambiguation details include:
If several records appear, choose the establishment that matches the location and activity you actually need rather than assuming the first result represents the entire company.
Yes. A multi-establishment enterprise can have different NAICS classifications across its locations when those establishments perform different primary activities.
In addition, some business profiles, commercial databases, and government contracting systems allow a business to identify multiple NAICS codes for the products and services it supplies. That is different from federal statistical classification, where statistical agencies assign one NAICS code to each establishment based on its primary activity.
See How Many NAICS Codes Can a Company Have? for the full distinction between establishment, enterprise, contracting, and additional-code uses.
The Small Business Administration says a business generally has a primary NAICS code but can have multiple NAICS codes when it sells multiple products and services.
Federal acquisitions work differently. Under FAR 19.102, contracting officers generally assign one NAICS code and corresponding size standard to a solicitation based on the industry that best describes the principal purpose of the supply or service being acquired.
If you are researching a company for a specific federal procurement, distinguish the company's general business profile from the NAICS code assigned to that solicitation.
These sources support the establishment-level classification rules, agency-specific assignment practices, current NAICS revision, and federal contracting distinctions described on this page.
Search the company name and identify the exact business location. Review the NAICS code associated with that establishment, then confirm the code against the location's actual activity and the current NAICS definition.
Not necessarily. A company with multiple establishments can have different NAICS classifications across its locations, and some business or contracting systems allow multiple relevant NAICS codes at the company level.
A database can provide a useful classification, but there is no central government agency that approves one universal NAICS code for every establishment and every use. Agencies and data providers maintain classifications for their own purposes.
The sources may represent different locations, use different evidence or assignment methods, reflect different update dates, or use different NAICS revisions.
Check the revision year and compare the code with the current 2022 NAICS structure. Some industry codes changed between 2017 and 2022, so an older record may contain a code that is no longer current.
Use the NAICS code assigned to the solicitation when evaluating that procurement. FAR 19.102 generally requires the contracting officer to assign the code that best describes the principal purpose of the acquisition.
A closer review can help when the business has multiple activities, several locations, conflicting database classifications, an older NAICS code, or a classification that will be used for targeting, underwriting, procurement, compliance, or another important decision.
