Data Identifiers


Today’s data-driven use cases and tomorrow’s innovation with AI and machine learning often rely on symbology. Whether it’s RIC, ISIN, PermID, LEI, SEDOL or another identifier, we have you covered.

Connecting your data through symbology

As the amount of data that your firm is using increases, so does the complexity. To get trades, analytics, risk management, compliance, and clearing and settlement done, you need to know that you are engaging with the right companies, financial instruments and more.

Symbology simplifies data complexity. It is the application of data-based identifiers that enable recognition of a security or a legal entity. There are a number of different identifiers that are deployed within the financial services industry for a range of different use cases.
