Welcome to the NIOSH Industry and Occupation Computerized Coding System (NIOCCS)

NIOCCS is a free web application used to translate industry and occupation text found in surveys, death certificates, and medical records into standardized codes so that researchers can analyze their data.

Everyone must register for a SAMS account to code a file in NIOCCS

SAMS is a “Secure Access Management Service,” developed by CDC to serve as a web application portal. Though your login experience may feel a bit different, it is now more secure.

You will need a SAMS account to be able to code a file in NIOCCS. Previous NIOCCS users also need to register for a SAMS account. We realize this is a new process – please don’t hesitate to contact us if you have questions.

Begin registering for your SAMS account:

Please email your (1) first and last name, and (2) email address to NIOCCS@cdc.gov. Once we receive your information, we can enter it into the system to send you an invitation to set up your SAMS account.


Get the industry and occupation codes for a single record or single record requiring crosswalk. You must have an account and will be required to log in before you can code a file
