How a NAICS code is built

Two digits name the sector, three the subsector, four the industry group, five the industry and six the national industry. 541511, Custom Computer Programming Services, sits in sector 54, subsector 541, group 5415 and industry 54151. Three sectors span several two-digit codes: Manufacturing is 31-33, Retail Trade 44-45, and Transportation and Warehousing 48-49. The 2022 edition counts 20 sectors, 96 subsectors, 308 industry groups, 689 industries and 1,012 national industries.

NAICS or SIC?

SIC is the older system, last revised in 1987. NAICS replaced it for federal statistics in 1997 and is revised every five years; this page uses the 2022 edition. Some databases and filings still use SIC codes, so a list built from several sources may need both.

From code to prospect list

Knowing how many companies sit behind a code tells you whether a market is a hundred accounts or ten thousand, before you pay for a single contact. I explain the method in Count before you buy a list.

Frequently asked questions

What is the NAICS code for software development?

541511, Custom Computer Programming Services, covers writing software to a customer's needs. Software that a company publishes and sells is 513210, Software Publishers.

How many digits does a NAICS code have?

Between two and six. The six-digit level, the national industry, is the most detailed, and the 2022 edition has 1,012 of them.

How do I find a company's NAICS code?

Different agencies assign or ask for codes for different purposes, so there is no single official register giving one NAICS code per company. Start from what the company does: search the activity here, then check the code against its official definition.

Is NAICS the same in Canada and Mexico?

The three countries share the system and its structure, and each adds its own detail at the most specific level. On census.gov, a T after a title marks industries that are comparable across the three countries.
