ISO 10383 Market Identifier Code (MIC) decoder — venue name, operator, country and status behind the 4-character exchange code, no auth.

Tools

• decode_mic(code) — decode one MIC (e.g. "XNYS", "XLON") to the venue’s market name, legal operator, LEI, country, city, website and registry status. Reports whether the code is an operating MIC (the venue operator as a whole, e.g. "XNYS" for the New York Stock Exchange) or a segment MIC (one specific market/order book under an operator, e.g. "ARCX", NYSE Arca, under "XNYS"). An operating MIC also carries segment_count — call search_mics with operating_mic to list them.
• search_mics(country?, operating_mic?, status?, name_contains?, limit?, offset?) — filter the registry. Returns aggregate counts first (total, by_status, by_country) and a page of rows after. Pass operating_mic to list every market under one venue operator; a zero-match combination names the filters tried rather than returning a bare empty array.

Complements openfigi: openfigi returns exchCode on a security’s exchange listing with no decoder for it — decode_mic is that decoder.

Data source

Publisher: ISO, delegated to ANNA (the Association of National Numbering Agencies) as the Registration Authority for ISO 10383 — the Market Identifier Code list, ~2,900 codes. The registry is published as a downloadable file only (no query API), so this pack answers from a baked table refreshed on a schedule rather than a live per-call fetch. data_as_of in every response is the capture time the answer reflects.

Licence. ISO 10383 is a published international standard; ANNA distributes the current MIC list for public reference use.

Two kinds of MIC

ISO 10383 itself distinguishes an operating MIC (the venue operator, e.g. "XNYS") from a segment MIC (one market under that operator, e.g. "ARCX" under "XNYS", or "XCHI", NYSE Texas, also under "XNYS"). A security’s exchCode can be either kind — decode_mic reports which, and for an operating MIC, how many segments sit under it.

Tools

• decode_mic — The venue name, operator, country and status behind an ISO 10383 Market Identifier Code.
• search_mics — Trading venues in the ISO 10383 Market Identifier Code registry, filtered by country, operator, status or name.
