An electronic account that holds shares and securities in digital format, replacing physical share certificates. Mandatory for trading on Indian stock exchanges.
A demat (dematerialised) account is an electronic account that holds shares and other securities in digital format. Just as a bank account holds money, a demat account holds your equity shares, government bonds, mutual fund units, and other securities. It is mandatory for anyone wanting to trade on Indian stock exchanges.
India transitioned from physical share certificates to dematerialised format following SEBI's mandate in 1996. Two central depositories manage all demat accounts: NSDL (National Securities Depository Limited) and CDSL (Central Depository Services Limited). As of 2024, there are over 15 crore active demat accounts in India — a number that has tripled since 2020, driven by mobile trading apps and the post-COVID retail investing boom.
To open a demat account, you need a PAN card, Aadhaar (for eKYC), bank account, and a Depository Participant (DP) — typically your Broker. Most discount brokers like Zerodha, Groww, and Angel One offer free demat account opening with annual maintenance charges (AMC) of Rs 0-300. Full-service brokers may charge Rs 500-700 annually.
Every demat account has a unique 16-digit number (e.g., starting with "IN" for NSDL accounts). Shares bought on the exchange are automatically credited to this account upon settlement (T+1). Shares can also be transferred between demat accounts (off-market transfer), pledged as collateral for margin trading, or inherited by nominees.
SEBI has introduced several investor protection measures for demat accounts: mandatory nomination (or opting out with declaration), two-factor authentication for online access, SMS alerts for debits, and the Basic Services Demat Account (BSDA) for small investors holding up to Rs 10 lakh, which has zero AMC charges. For IPO applications, the demat account must be linked to UPI for the ASBA (Application Supported by Blocked Amount) process.
