Information on the administration of county-district-school (CDS) codes, which is the Department’s method for tracking California schools. Includes resources and information for obtaining a CDS code and maintaining directory information.

County-District-School (CDS) Codes

The California Department of Education (CDE) is required to report Directory information annually to the U.S. Department of Education (ED) through the EDFacts Submission System (ESS). To meet this federal requirement, the CDE uses the County-District-School (CDS) code system. Additionally, the administration of CDS codes provides the CDE, as well as other state agencies and postsecondary institutions, with a basis for tracking schools and districts in California.

The 14-digit CDS code is the official, unique identification of a school within California. The first two digits identify the county, the next five digits identify the school district, and the last seven digits identify the school.

CDS codes are not assigned to programs. Evidence that the entity is a school rather than a program is provided by the governing board action approving formation of the school and board action establishing the school. Governing boards can act only by a majority vote at a public meeting (Education Code sections 1011, 1013, 1040, 35163, 35164; Government Code section 54950 and following [the Brown Act]).
