Industry Codes (KYB)

How to classify a business with a NAICS industry code when creating a corporate application, including the two-tier selection and code format.

When creating a corporate application, classify the business with an industry code in the industry field. Rain uses NAICS (North American Industry Classification System) codes for this purpose.

Both 2017 and 2022 NAICS classification versions are supported.

How it works

Industry selection uses a two-tier system:

1. Major industry: select from one of 20 broad industry categories.
2. Specific industry: choose a specific industry within that category.

The final industry value is a 6-digit NAICS code that identifies the business type.

The API validates industry against Rain’s accepted NAICS list and returns a 400 for any other value. The industry’s title (for example, Soybean Farming) is also accepted in place of the code, but it must match Rain’s list exactly, so send the code. The field is optional: an application without it is accepted, but Rain recommends sending it.

Major industry categories

Select from one of these 20 major categories:

Code	Category
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

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

NAICS code format

NAICS codes are 6-digit numbers where:

• The first 2 digits identify the major industry sector
• The remaining digits provide increasing specificity

For example, within the Agriculture, Forestry, Fishing and Hunting sector (11):

• 111110: Soybean Farming
• 111140: Wheat Farming
• 111310: Orange Groves

For the full list of NAICS codes, refer to the official NAICS website.
