Total Zones and Divisions in Indian Railways as on 17.07.2023

Sub: Standardized alphabetical codes for Zones & Divisions.

To avoid any mismatch/contradiction in the codes of Zones and Divisions maintained separately in multiple IR-applications by CRIS & Rate Branch System (RBS), Board (CRB & CEO) has approved the use of standardized alphabetical codes for Zones and Divisions across Indian Railways. The list of standardized codes for the above enclosed herewith for ready reference.

The above directives have been put forth to ensure standardization and uniformity in the coding system employed across all Indian Railways applications. It is essential that these instructions are duly implemented within all IR-applications & in each zonal railway to ensure seamless integration and compatibility across the network and due consideration is given to Upper and lowercase while using the codes.
The older codes on stations, other installations and rolling stock should be gradually replaced by the above standardized codes of Zones and Divisions during next painting cycle/POH etc
