What is CUSIP Number?
A CUSIP number is a unique nine-character alphanumeric code used to identify North American financial securities for clearing and settlement. It helps investors, traders, and regulators precisely track individual securities like stocks and bonds.
This system, managed by FactSet Research Systems Inc., standardizes security identification to avoid confusion and streamline transaction processing.
Key Characteristics
The CUSIP number is structured to convey issuer and security details clearly and efficiently:
- Issuer Identifier: The first six characters uniquely identify the issuing entity, similar to how a C-corporation is uniquely recognized.
- Issue Details: Characters seven and eight specify the exact security type and issue, such as bonds or stocks.
- Check Digit: The ninth character is a checksum digit that verifies the code's accuracy to prevent errors.
- Standardization: Allows for consistent tracking across multiple platforms and databases including bond ETFs like those listed under best bond ETFs.
How It Works
The CUSIP number functions as a security's barcode, enabling seamless trade clearance and settlement. When you transact with securities such as those from BND, your brokerage uses the CUSIP to identify the exact asset.
Issuers and financial institutions assign CUSIPs through a centralized service, ensuring each security issued by a company or municipal entity has a distinct identifier. This system also integrates with global identifiers for international securities.
Examples and Use Cases
CUSIP numbers are essential in diverse investment scenarios, helping you manage and verify your holdings:
- Corporate Bonds: When investing in bonds issued by companies like Delta, the CUSIP ensures you track the correct issue amid multiple offerings.
- Municipal Securities: City bonds and revenue bonds use CUSIPs to simplify settlement and income payments.
- ETF Investments: Funds tracking indexes such as the EAFE Index rely on CUSIP codes to identify component securities precisely.
Important Considerations
While CUSIPs provide accurate security identification, they are primarily limited to North American issues. For global securities, alternative systems may be necessary. Understanding how CUSIPs interface with tools like discounted cash flow (DCF) models can enhance your investment analysis.
Always verify CUSIP numbers through official sources or your brokerage to avoid transaction errors, especially when dealing with complex securities or lesser-known issuers.
Final Words
CUSIP numbers uniquely identify financial securities, ensuring precise tracking and settlement in the market. To verify or research a specific security, check official databases like EMMA or consult your broker for the exact CUSIP code.
