What is a ticker symbol?
A short alphabetic code used to uniquely identify a publicly traded security on a stock exchange (e.g., AAPL for Apple, MSFT for Microsoft).
Also known as: stock symbol, ticker
A ticker symbol is the stock market's primary key. NYSE and Nasdaq tickers are 1-5 letters (F, IBM, GOOGL); other exchanges use longer codes or include suffixes for share class and listing venue (BRK.A, RDS-A, TSLA.MX). Within an exchange, a ticker is unique; across exchanges, the same letters can refer to entirely different companies, which is why the exchange has to be specified to avoid ambiguity.
For data systems, a ticker plus an exchange is the canonical key for a listed company. ISIN (an international 12-character code) is the more rigorous global identifier and is what most institutional systems standardize on, but tickers are what humans use and what most consumer-facing tools display.
For brand-data use cases, a ticker is the bridge between a website and its public financials. Given apple.com, returning ticker AAPL on NASDAQ lets a downstream system pull SEC filings, market cap, and ownership disclosures. Brand.dev's retrieve-by-ticker endpoint goes the other way: given the ticker, return the brand profile.

FAQ
Ticker vs ISIN?
ISIN (12 alphanumeric characters) is the global standard and is unambiguous across exchanges. Tickers are shorter, more human-readable, and exchange-scoped. Institutional systems use ISIN; retail platforms and news headlines use tickers.
Why does Google have GOOG and GOOGL?
Two share classes. GOOG is Class C (no voting rights), GOOGL is Class A (one vote per share). Same company, different securities, separate tickers.
How do I look up a ticker from a domain?
For public companies, services like Brand.dev or financial-data APIs map domain to ticker via SEC filings and corporate registries. For private companies, there is no ticker because there is no public listing.
