F-0 Message Type Indicator
Description
MTI stands for Message Type Indicator.
- This is the part of the message that indicates what the purpose of the message is. For example, a message could be initiated by an acquirer requesting that the payment for a purchase be authorized by the issuer. Or, a message could be a response from the issuer that the payment has been authorized or declined. Similarly, another example could be a message that was initiated by the issuer to reverse a payment (in case of a payment dispute). There are many such purposes covering simple financial information exchange, administrative tasks and settlements. Each of these can be communicated using the message type indicator.
- The message type indicator also contains information about who originated the message (acquirer or issuer).
