Automotive SIC codes to automotive NAICS codes reference

Knowing automotice SIC codes and automotive NAICS codes is usually the first step in picking an automotive business-to-business mailing list. You’ll usually see B-to-B mailing lists defined by auto parts Standard Industrial Classification (SIC) codes. Sometimes you’ll see North American Industry Classification System (NAICS) codes. These codes describe a wide variety of automotive businesses including auto repair and car dealerships.

One problem with automotive SIC codes is that SIC codes are an outdated system and very broad by their definition. Automotive SIC codes were replaced with automotive NAICS codes in the 1990s, which also get updated every five years or so. Even with automotive SIC codes being outdated, a lot of B2B automotive mailing list data still relies on SIC codes to identify businesses in the automotive aftermarket.

NAICS codes are from two to six digits long, creating five levels of detail. The highest level is two digits and includes the largest number of businesses in a particular category; for example codes beginning with 44 or 45 represent retail businesses. NAICS is a hierarchical system that gets more precise and targeted as you add digits; for example 4413 represents Automotive Parts, Accessories, and Tire Stores within the retail category. 441320 narrows it to Tire Dealers only.

Automotive SIC codes, SIC codes for auto repair…how’d it all start?

Using automotive SIC codes for business-to-business lists is sometimes necessary, but today automotive businesses are categorized by automotive NAICS codes (North American Industry Classification System). These automotive industry codes were created by the Federal government in 1997 and then revised in 2007, 2012 and again in 2017 (and valid through 2021). NAICS automotive classifications were intended as a replacement to the older automotive SIC Codes. NAICS codes are more precise for identifying automotive businesses. Even today, SIC codes are more commonly used for automotive business data. Even when using new NAICS codes, it’s important to know that many automotive businesses aren’t accurately classified or may qualify for more than one NAICS code. We sometimes can get around this problem in email marketing by using a combination of business classification codes plus validated business keywords to help identify specific businesses.
