Security Identifiers

There are several standard identifiers for securities, depending on their asset category and where they originate. Some of the most common include:

  • CUSIP
  • WI-CUSIP
  • ISIN
  • SEDOL
  • CEDEL
  • Ticker Symbol

However, in addition to these standard identifiers almost every broker or custodian has their own internal symbol. When you receive security data from these sources, sometimes you'll receive one identifier type for one security and another for something else, or sometimes no identifier. The Security Master Service can translate between all these identifiers and more. We can create custom maps to custodians, brokers and other data sources. We can research securities with no ID present.

Our system works by assigning a unique internal identifier to every security that comes through the system. This allows us to track securities accurately, particularly when an Identifier changes, such as the case with a WI (When Issued) ID with CUSIPs.
