Stock Ticker Suffix by Exchange

Find the Yahoo Finance / Bloomberg suffix for any exchange

Look up the Yahoo Finance ticker suffix and ISO 10383 MIC for any global stock exchange. Map exchange names to the .L, .TO, .HK and other suffixes needed by financial data APIs.

What is a ticker suffix?

A ticker suffix is a short extension such as .L or .TO that financial data providers append to a stock symbol to identify which exchange it trades on. The same company can have different suffixes on different APIs.

Stock ticker suffix by exchange

Most financial data APIs identify a security by combining a local symbol with an exchange-specific suffix. Yahoo Finance, for example, returns no data for BP on its own but works for BP.L, because the .L suffix tells it to look on the London Stock Exchange. This reference maps exchange names, countries, and ISO 10383 MIC codes to the suffix you need.

How it works

Yahoo Finance assigns each non-US exchange a short dotted suffix that is appended to the bare ticker. The mapping is provider-specific: the London Stock Exchange is .L on Yahoo but LN on Bloomberg. US exchanges (NYSE, NASDAQ, NYSE American) are the default and carry no suffix on Yahoo. The MIC column shows the ISO 10383 Market Identifier Code, a standard four-letter identifier used across professional trade-reporting and many data feeds when a dotted suffix is not available.

To build a usable symbol: take the local ticker exactly as it trades (preserving leading zeros on Asian numeric symbols, for example 0700.HK), then append the suffix from the matching row.

Tips and examples

  • Asian numeric tickers keep their full digit string: Toyota is 7203.T, not 7203.
  • Some markets share a country but use distinct suffixes — India splits into NSE (.NS) and BSE (.BO), and the same stock exists on both.
  • Euronext venues each have their own suffix (.PA, .AS, .BR, .LS) even though they share one trading platform.
  • When a suffix returns nothing, double-check that the security is actually listed on that exchange — dual-listed shares may need a different venue.
