Type Codes
What Is a Type Code?
A type code is a two-digit type number that identifies the type of employer an employee works for or the type of job an employee performs. See the list of type codes that are valid for each system.
Reporting Charts to Assist Employers with Type Codes
Several charts are provided to assist employers in selecting the correct type code. In determining type codes, there is a hierarchy for reporting employees based on their retirement status, and the type of position in which they are working.
The charts must be used in the order as listed. When determining type codes, retirees take precedence over all types of reporting.
- Retiree Returning to Work Reporting Charts. These charts include retirees returning to eligible, ineligible and substitute positions. If your employee isn't a retiree, go to number 2.
- Substitute Reporting Chart. If your employee does not fit this category, go on to number 3.
- List of Type Codes by System for employees working in one eligible position.
- If your employee is working in more than one system, refer to each system's Plan Rules.
Setting up an employee (eligible for retirement membership) with the correct type code is an important responsibility of the employer. If you are uncertain as to what type code to use, please contact ESS.
