How to Convert Sic Code to Naics Code

In 1997, the North American Industry Classification System (NAICS) was developed and adopted to replace the Standard Industry Classification (SIC) System. Converting a SIC code into the appropriate NAICS code is easily done by using various NAICS reference files and tools. You can order a printed or digital copy of the entire list from the National Technical Information Service or convert your SIC code online by accessing the current statistics for your industry.

Instructions

1. Access the United States Department of Labor's SIC Division Structure webpage (see References below) and verify your four-digit SIC code by locating your industry division, major group and industry group. For example: a heating and air contractor would click on division C, major group 17 and locate a SIC code of 1711.

2. Go to the NAICS Association website and enter your SIC code in the SIC code search box. Click "SIC search" to find the corresponding NAICS code.

3. Read the resulting SIC descriptions and select the NAICS title and code that matches your industry.

Tips & Warnings

• Anyone in the insurance industry or anyone completing multiple business reports may benefit from ordering printed materials, which are available on the NTIS website.

• If you have any questions when reviewing the NAICS titles and descriptions, contact your insurance carrier for assistance.
