DIN and DSC Explained: What Every Director Needs

Company Registration

11 Oct 2026 · company-registration, mca

Before you can sign incorporation forms, every director needs two things: a DIN and a DSC. Both are simple to obtain but easy to confuse.

DIN vs DSC

A DIN is a unique number that identifies you as a director. A DSC is a digital key that lets you sign documents electronically. You need the DSC to file, and the DIN to be recognised as a director.

How to get them

A DSC is issued by certified authorities after identity verification. A DIN is generally applied for through the incorporation filing itself for first-time directors.
