How to Read a NAICS Code ?

The first two digits designate the largest business sector, the third digit designates the subsector, the fourth digit designates the industry group, and the fifth digit designates particular industries. The last digit designates national industries.

For Example :

Sector 11 Agriculture, Forestry, Fishing, Hunting
Subsector 111 Crop Production
Industry Group 1113 Fruit and Tree Nut Farming
Industry 11133 Non-citrus Fruit and Tree Nut Farming
U.S. Industry 111331 Apple Orchards
The NAICS numbering system employs six-digit code at the most detailed industry level. The first five digits are generally (although not always strictly) the same in all three countries. The first two digits designate the largest business sector, the third digit designates the subsector, the fourth digit designates the industry group, the fifth digit designates the NAICS industries, and the sixth digit designates the national industries
