Scope

Specifies a universal method of identifying exchanges, trading platforms, regulated or non‑regulated markets and trade reporting facilities as sources of prices and related information, for use where instruments are listed, where trades are executed, and where trade details are reported. Market Identifier Codes are to be registered at operating/exchange and market‑segment level, with clear links between segment and operating MICs.

Key topics and requirements

• Definition and structure of the Market Identifier Code (MIC) — a four‑character alphanumeric identifier.
• Rules for registering MICs at both operating/exchange and market‑segment levels and for linking segment MICs to their operating/exchange MIC.
• Requirements for publication and maintenance of the MIC lists and guidance on accessing the official MIC register.
• Examples and a normative annex describing how to access and use MIC data in automated systems.

Typical use and users

Used by exchanges, trading platforms, market data vendors, brokers, clearing houses, investment firms, regulatory reporting systems, FIX/market‑data integrators, and IT teams that build trading, market‑data or trade‑reporting applications. MICs are widely used in message standards and data feeds to unambiguously identify trading venues.

Related standards

Standards commonly referenced with ISO 10383 include ISO 6166 (ISIN — International Securities Identification Number), ISO 10962 (CFI — Classification of Financial Instruments), and ISO 9362 (BIC). These standards all fall under ISO/TC 68 (financial services) and are used together in securities identification and messaging contexts.
