Market Identifier Codes (MIC)
A Market Identifier Code 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.
The International Organization for Standardization (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 the MIC Registration Authority 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 monitor developments in their market and if there are changes advise the exchange/trading platform and ask them to inform the MIC Registration Authority via the MIC website (www.iso10383.org).
It is important to identify any changes that have a direct impact on the accuracy of the MIC list the Registration Authority maintains – such as the addition of new exchanges and/or trading platforms in their market.
The current MIC codes, which are updated on a monthly basis, are available from the ISO website and may be accessed here.
