CUSIP

A CUSIP (/ˈkjuːsɪp/) is a nine-character numeric or alphanumeric code (e.g. 037833100 for Apple) that uniquely identifies a North American financial security for the purposes of facilitating clearing and settlement of trades. All CUSIP identifiers are fungible, which means that a unique CUSIP identifier for each individual security stays the same, regardless of the exchange where the shares were purchased or venue on which the shares were traded.^[1] CUSIP was adopted as an American national standard by the Accredited Standards Committee X9 and is designated ANSI X9.6. CUSIP was re-approved as an ANSI standard in December 2020. ^[2][3] The acronym derives from Committee on Uniform Security Identification Procedures.

The CUSIP system is owned by the American Bankers Association (ABA) and is operated by FactSet Research Systems Inc.^[4] The operating body, CUSIP Global Services (CGS), also serves as the national numbering agency (NNA) for North America, and the CUSIP serves as the National Securities Identification Number (NSIN) for products issued from both the United States and Canada. In its role as the NNA, CUSIP Global Services (CGS) also assigns all US-based ISINs.
