Are NAICS Codes State-Specific? National vs. State Classifications

Compiled & reviewed by the EntityCodes Editorial Team (Tech Labs FZ LLC) · Data verified: 2026-06-28

NAICS codes are standardized at the federal level by the U.S. Census Bureau and are uniform across all 50 states.

Federal Uniformity of NAICS Classifications

The North American Industry Classification System (NAICS) is a federal standard developed cooperatively by the U.S. Census Bureau, Statistics Canada, and Mexico's INEGI ^[1]. There is no such thing as a state-specific NAICS code list. A code representing a specific industry—such as 238160 for Roofing Contractors—remains exactly the same whether your business operates in California, Texas, Florida, or New York.

How States Use Federal NAICS Codes

While the codes themselves are uniform, individual state agencies utilize the federal system for local regulatory and tax compliance purposes:

Secretary of State Registrations: When forming an LLC or corporation, many states require you to declare a NAICS code to describe your primary business purpose.
State Department of Revenue: State tax authorities use the codes to classify businesses for state payroll taxes, workers' compensation rates, and sales tax reporting.
Local Business Licensing: Municipalities and counties often require a NAICS code on local business tax applications to determine the correct permit tier.

To register or report your industry classification in any state, simply locate your standard six-digit federal code using the main registry search tool ^[1].

Official Regulatory References & Mappings

To support the core compliance tasks detailed in this guide on Are NAICS Codes State-Specific? National vs. State Classifications, compliance officers and corporate attorneys must consult several official databases. The foundational structure of these codes is governed by the U.S. Census Bureau North American Industry Classification System (NAICS) Manual. Recent modifications and updates to these classifications are published formally in the Federal Register NAICS Update for 2022 Notice in the Federal Register. When preparing federal tax filings, these classifications map to specific activities under the guidance of the Internal Revenue Service (IRS) Instructions for Schedule C (Form 1040) Principal Business Activity (PBA) Codes. For government procurement, small business status is cross-referenced using the U.S. Small Business Administration (SBA) Table of Small Business Size Standards and the detailed regulations codified in the Electronic Code of Federal Regulations (eCFR) 13 CFR Part 121 - Small Business Size Regulations. International classifications are maintained by the United Nations and can be compared via the United Nations Statistics Division International Standard Industrial Classification of All Economic Activities (ISIC). Implementation policy directives are issued under the authority of the Office of Management and Budget (OMB) NAICS 2022 OMB Statistical Policy Directive No. 8. Labor and employment statistics are organized using the Bureau of Labor Statistics (BLS) NAICS Classifications in BLS Labor Statistics Programs, macroeconomic data is mapped to the Bureau of Economic Analysis (BEA) Industry Economic Accounts Guide and NAICS Usage, and local establishment counts are audited through the U.S. Census Bureau County Business Patterns (CBP) Economic Data Methodology.

💡 Expert Guidance: State vs. Federal NAICS Database Discrepancy

A common pitfall is assuming that the NAICS code you select for your state LLC filing or state franchise tax portal automatically updates your federal registrations. State departments of revenue often maintain independent databases and might accept legacy or simplified codes, whereas federal systems like SAM.gov strictly enforce the active Census NAICS vintage.

Frequently Asked Questions

Is there a different NAICS code list for Florida or California? ▾

No. All states use the identical federal NAICS list published by the U.S. Census Bureau.

How do I report my NAICS code to my state? ▾

You enter your standard six-digit NAICS code on your Secretary of State registration documents, state tax filings, or annual reports.

Is a NAICS code issued by state governments or a federal agency? ▾

NAICS codes are established by the federal government (U.S. Census Bureau) as a nationwide classification system. They are not issued by state governments, though state agencies adopt the federal system.

Do I use the same NAICS code for federal taxes and state LLC registrations? ▾

Yes. Because NAICS is a standardized federal classification, you use the identical six-digit code to describe your business activity on state LLC filings, federal tax returns, and bank profiles.

Why does my state's Secretary of State request a NAICS code? ▾

State Secretaries of State request a NAICS code during business formation to categorize the economic activity of new corporations and LLCs for state statistical analysis and tax program eligibility.

Can a state department assign a unique custom NAICS code to my business? ▾

No. State departments cannot create custom NAICS codes, as they must conform to the official six-digit classifications published in the U.S. Census Bureau NAICS manual.

Are there state-level tax exemptions linked to specific NAICS codes? ▾

Yes. Many states provide sales tax exemptions, energy rate reductions, or enterprise zone tax credits to businesses operating under specific NAICS codes (such as manufacturing or agriculture).

Does a state-specific license require a matching NAICS code? ▾

While state licensing boards (such as plumbing or electrical boards) regulate specific trades, they do not require a specific NAICS code, though your declared code on filings should match your trade.

What is the difference between a NAICS code and a state tax ID? ▾

A NAICS code is an industry classification number shared by all businesses in the same trade. A state tax ID is a unique account number assigned exclusively to your business for state tax reporting.

How can I verify which NAICS code my state has recorded for my business? ▾

You can verify this by pulling a copy of your filed articles of organization, reviewing your state corporate registry profile, or checking your state tax registrations.
