A Trading Number (or Trading Member ID) is the unique identification code assigned by a stock exchange to a registered stockbroker or trading member, used to identify the broker in all market transactions. Every order placed on NSE or BSE is linked to the trading member ID of the broker through whom it is routed, ensuring transparency and accountability in the audit trail. For investors, knowing their broker's trading member ID is useful when resolving disputes, verifying trade confirmations, or referencing transactions in regulatory communications. Ventura Securities has its own registered trading member IDs on NSE and BSE.
