ANSI X9.6:2020 pdf free download – Committee on Uniform Security Identification Procedures Securities ldentification CUSIP
1 Scope
This standard provides specifications for identifying an eligible security, financial instrument, or other investment media referred to hereinafter as an issue. It uniquely identifies the issuer, and with a few exceptions for high-volume fixed income programs, the issue as well. It shall serve as the common denominator in communications among users for completion of transactions and exchange of information. It specifies both the configuration of the number and the meaning attached to each portion. (See Informative Annex C 8.2 for more information)
2 Terms and Definitions
2.1 Check digit A Modulus 10 Double-Add-Double technique is used as a means of verifying the CUSIP number. (See Normative Annex A for an ilustration.)
2.2 CUSIP number The term that refers to the whole alphanumeric number that uniquely identifies issuers and issues and, with few exceptions for high-volume fixed income programs, of financial instruments. (See Informative Annex C.8.1 for more detail on additional issuers and C.5.2 for the issue exceptions.)
3.2 Issuer number
To facilitate the assignment of issuer numbers corporate and governmental issuers are commingled to form a single alphabetic issuer file. An issuer number of six characters is assigned based on the alphabetic sequence of each eligible issuer of securities or financial instruments. One number is assigned to each issuer, except where two character issue numbers are not sufficient to accommodate all outstanding issues with their various rates and maturities. In such instances, the next sequential issuer number is assigned unless it is unavailable, in which case an overflow issuer number shall be assigned. Issuer numbers 900 to 989 in each group of 1 ,000 available numbers are reserved for overflow. Numbers in the overflow area are assigned in ascending sequence to any issuer which cannot be accommodated within its proper alphabetic position in the proceeding 900 issuer numbers. Issuer numbers 990 to 999 in each group of 1 ,000 available are reserved for each independent user of the standard. The practical effect of providing an overflow mechanism may be seen in the manner in which direct access to all issuers in the directory is accomplished clerically, without need for a cross-reference file lookup. If the name is found in the appropriate alphabetic sequence, reference is then made to the 900 section of that series. If the issuer has been assigned an overflow number, it shall be in this location. Similarly, providing user assigned numbers permits a user to identify any issuer not assigned a CUSIP number for which a user has a holding, and still achieve reasonable alphabetic sequencing within that user’s file.
