What is a NAICS Code?

A NAICS code is a six-digit number the United States government uses to identify exactly what a business does. NAICS stands for the North American Industry Classification System. Since its introduction, it has become the universal standard relied upon by federal agencies, banks, lenders, and insurance companies across the country whenever they need to determine a business’s primary industry.

Every business operating in America is expected to know and use its correct code. Yet, because the government’s official classification manual is filled with dense regulatory jargon, finding the right number is often a frustrating guessing game for business owners.

We built NAICS Code Search to fix that. Instead of digging through hundreds of pages of confusing federal text, you can simply search what you actually do—whether that is “running a restaurant,” “software development,” or “auto repair”—and find your accurate six-digit code instantly.

Why Your NAICS Code Matters

A correct NAICS code reaches much further into your business operations than most owners realize. It is not just a box you check on a form; it actively determines your business’s financial, legal, and operational opportunities.

Getting your classification wrong can quietly disqualify your business from funding, overcharge you for insurance, or make you invisible to potential partners. Here is how your NAICS code impacts your business:

Federal Contracting and Government Grants

Every federal contract listed on SAM.gov is tied to specific NAICS codes. Government agencies use these codes to find small businesses that provide the exact services they need. If you register under the wrong code, you will miss out on lucrative contracts and set-aside opportunities that were specifically meant for your industry.

Small Business Administration (SBA) Loans

The SBA uses NAICS codes to determine which loan programs your business qualifies for, as well as what their “size standards” are. A manufacturing business and a retail business have entirely different revenue thresholds to be considered a “small business.” The wrong code can instantly disqualify you from the financing you are entitled to.

State and Local Tax Registration

Most state and local governments require a NAICS code the moment you register a new business entity or apply for a local license. From day one, this code becomes part of your permanent public record, dictating your local tax obligations and industry-specific zoning requirements.

Commercial Banking and Credit

Banks rely heavily on NAICS codes to assess risk when you open a business account or apply for a line of credit. Because certain industries carry inherently higher financial risks, a wrong classification can trigger unnecessary compliance flags or result in your loan application being denied.

Insurance Premiums

Insurance providers calculate premiums based on industry risk. For example, a roofing contractor (Code 238160) carries a much higher physical liability risk than a graphic design firm (Code 541430). If your code is misclassified, you will likely pay significantly more for commercial coverage than you should.

Investor and B2B Visibility

On a broader scale, NAICS codes are how market analysts, private investors, and B2B partners research industries. Using the correct code ensures your business shows up in the right industry data reports, putting you in front of the exact people looking to invest in or partner with your specific sector.

About the 2022 NAICS Code List

The Office of Management and Budget (OMB) reviews and updates NAICS codes every five years to reflect changes in the U.S. economy. The 2022 NAICS Edition is the version currently in force.

Every code in our NAICS code search database is pulled directly from this 2022 official dataset. We do not use retired editions, and we do not rely on outdated classifications. The next scheduled revision by the federal government is set for 2027, and until then, this is the definitive standard that businesses, lenders, and agencies are working from.

How the Code Structure Works

The NAICS code list is organized in a drill-down structure, moving from broad categories to highly specific ones:

• 2-Digit Code (Sector): Represents the broadest level of the economy (e.g., Code 31-33 is Manufacturing).
• 3-Digit Code (Subsector): Narrows down the sector (e.g., Code 311 is Food Manufacturing).
• 4-Digit Code (Industry Group): Gets more specific (e.g., Code 3118 is Bakeries and Tortilla Manufacturing).
• 5-Digit Code (NAICS Industry): Highly specific (e.g., Code 31181 is Bread and Bakery Product Manufacturing).
• 6-Digit Code (National Industry): The most precise classification available (e.g., Code 311811 is Retail Bakeries).

Browse NAICS Codes by Sector

The NAICS system organizes all business activity into 20 major sectors, and every six-digit code belongs to one of them.
