Are SDO and SDM the Same?
In many states, especially Bihar, Uttar Pradesh, Madhya Pradesh, and Rajasthan, the terms SDO and SDM are used interchangeably. However, technically they are not always the same:
- SDM (Sub-Divisional Magistrate) is a post with magisterial powers under the Criminal Procedure Code (CrPC).
- SDO (Sub-Divisional Officer) is a broader term that refers to officers from various departments — Revenue, PWD, Irrigation, Electricity, etc. Each department may have its own SDO.
So, while every SDM is an SDO (administrative head), every SDO is not necessarily an SDM. The SDM is a specific magisterial designation, while SDO is departmental.

SDO vs SDM — Who is More Powerful?

SDO, on the other hand, handles departmental administration like irrigation, power, or public works but does not have magisterial authority.
