MIC & ISO 10383

Codes for exchanges and market identification (MIC)

The international standard ISO 10383 (Market Identifier Code – MIC) specifies a universal method of identifying exchanges, trading platforms and regulated or non-regulated markets as sources of prices and related information in order to facilitate automated processing. ISO have appointed SWIFT as the Registration Authority for ISO 10383.

As each National Numbering Agency is deemed the best placed entity to monitor and track developments in their respective jurisdiction, assistance in the coordination of the current MIC list maintained by SWIFT is deemed an important element of the NNA function in that market. As the importance of using MIC increases with the continuing evolution towards security processing automation, each NNA is requested to proactively monitor developments in their market and if there are changes, either advise SWIFT directly or as has been the practice in the past, inform the ANNA Secretariat of such changes. It is important to identify any changes that have a direct impact on the accuracy of the MIC list SWIFT maintains – such as the addition of new exchanges and/or trading platforms in their market or the closure of such entities.

The actual MIC codes which are updated on a monthly basis are available from the following website
