What are SIC Codes and NAICS Codes?
SIC Codes and NAICS Codes Defined
SIC stands for Standard Industrial Classification and NAICS stands for North American Industry Classification System. These are commonly used industry codes in the US, Canada, and Mexico. These universal numbering methods help identify the industry affiliation of a company. Dun & Bradstreet provides both codes in its business information products, such as company profiles in D&B Hoovers® and business credit reports in D&B Credit Intelligence.
Standard Industrial Classification codes were developed by the federal government in conjunction with the US business community during the 1930's. SIC codes have been proven to be a useful tool for professionals looking to segment domestic markets, analyze customer relationships, and conduct general business research.
SIC codes divide all major economic activity into 10 major divisions. The first two digits describe the nature of this activity in very general terms (i.e. Mining, Construction, Manufacturing). Remaining digits break down these categories into specific products and sub-industries.
In a Dun & Bradstreet company profile or business credit report, if more than one SIC code is assigned to a company, the first one listed is the primary line of business. The remaining codes, if any, comprise at least 10% of the firm's annual revenue.

The North American Industry Classification System (NAICS) was introduced in 1987 as a replacement for SIC codes and now serves as the standard for the three NAFTA countries of Mexico, Canada and the US.
Developed at the urging of leading business economists, NAICS (pronounced "nakes") offers classifications that more closely reflect the many new industries that have re-shaped the US and global economy. NAICS differs from SIC in that it focuses on business processes rather than on end products. NAICS also captures many service industries currently underrepresented in the SIC system.
There are hundreds of NAICS codes, once they are expanded into 4-, 5-, and 6-digit level.
Here is a list of the main 2-digit NAICS categories:
| 11 | Agriculture, Forestry, Fishing and Hunting |
| 21 | Mining, Quarrying, and Oil and Gas Extraction |
| 22 | Utilities |
| 23 | Construction |
| 31-33 | Manufacturing |
| 42 | Wholesale Trade |
| 44-45 | Retail Trade |
| 48-49 | Transportation and Warehousing |
| 51 | Information |
| 52 | Finance and Insurance |
| 53 | Real Estate and Rental and Leasing |
| 54 | Professional, Scientific, and Technical Services |
| 55 | Management of Companies and Enterprises |
| 56 | Administrative and Support and Waste Management and Remediation Services |
| 61 | Educational Services |
| 62 | Health Care and Social Assistance |
| 71 | Arts, Entertainment, and Recreation |
| 72 | Accommodation and Food Services |
| 81 | Other Services (except Public Administration) |
| 92 | Public Administration |
Like the SIC code, NAICS is organized into hierarchical classification groups that build from the detailed industry level. The United States, Canada and Mexico share the first five digits within the NAICS structure. The sixth digit is designed for country specific classifications and may differ from one nation to the next. However, the three countries have agreed to use many of the same six-digit designations.
While SIC codes are still widely used, the federal government no longer supports and maintains this system.
Industry codes are used for a variety of business and economic purposes that depend on accurate data to make informed decisions. Industry analysis is helpful for both sales and marketing and for risk management. Sales and marketing professionals can use industry codes for prospecting and lead generation. For example, companies might prospect for new customers in a particular geographic location and a particular industry, such as medical distributors in California. This type of targeting by industry can yield more precision for sales and marketing campaigns. Similarly, finance professionals can group their customers by industry and payment behavior to better understand which types of businesses may present a higher or lower level of risk.
