MT103cov is a message type used in the SWIFT financial messaging network, specifically for conveying payment instructions along with additional coverage information for a specific transaction. It is an extension of the standard MT103 message, which is used for customer credit transfers. The "cov" in MT103cov stands for "coverage," indicating that this message format includes details related to compliance, risk management, or additional transaction-related information. This enhances transparency and helps financial institutions manage cross-border transactions more effectively.
