Talk:International Securities Identification Number

message: There seem to be some differences in ISIN and CUSIP validation that need to be made more clear.  Let me see if I have it right:
In ISIN:
# The letters are converted to digits (becoming two seperate digits)
# The numbers are split into two groups
# The digits from one group (the one which contains the right most character) are multiplied by two
# The digits are summed
# etc
In CUSIP:
# The characters are split into two groups
# The digits from one group (the one which contains the right most character) are multiplied by two (letters being converted to numbers before multiplying)
# The digits are summed
# etc
 
So ISIN splits a letter ('C' for example) into '1' and '2' and puts them in different groups, where CUSIP groups then multplies 12 x 2

CUSIP also detailed here: http://www.cusip.com/NASApp/cusipweb/com/sp/apps/cusipaccess/html/whats.html#check

thread_title: ISIN and CUSIP difference

message: Shouldn't this sentence:
</em>ISINs are created only for securities, and not derivatives such as options or futures.</em>
Read:
ISINs are created only for EQUITIES, and not derivatives such as options or futures.
Since technically options and futures ARE securities?
See Security (finance)
Security is the legal right given to a creditor by a borrower.
In modern commerce, the creation of fungible credit, such legal interest became transformed as business people accepted the notes of third parties that were backed by credit worthy parties (banks). As a consequence a security became a type of transferable interest representing financial value. Traditionally, securities have been categorized into debt and equity securities, and between bearer and registered securities.
The uses that are made of securities have changed over time, for both the issuer and holder. Though the purpose of capital raising has sometimes been taken to be a defining characteristic of securities, its uses have expanded greatly in modern times.
They are often represented by a certificate. They include shares of corporate stock or mutual funds, bonds issued by corporations or governmental agencies, stock options or other options, limited partnership units, and various other formal "investment instruments." Banknotes, checks, and some bills of exchange do not fall into this category. Transferable interest in commodities like oil, food grains or metals can also be referred to as securities. One can enter into contracts to buy or sell various quantities of commodities in various commodity exchanges. These become transferable interest in the particular commodity.

replies: text: No, Security is still right, because it includes both Equities AND Bonds.  So maybe "but not" instead of "and not".  (GAVollink)  — Preceding unsigned comment added by 167.206.189.6 (talk) 16:25, 28 October 2011 (UTC)

message: The CUSIP bureau claims that anyone who uses CUSIP numbers in a database needs to pay the CUSIP bureau a licensing fee, since they say that their numbers are copyrighted.  
Are ISINs free for anyone to use?  Does the CUSIP bureau complain about this?  —Preceding unsigned comment added by 75.146.141.142 (talk) 19:00, 11 June 2008 (UTC)

message: A recent edit said:
: This doesn't seem to work for Portuguese ISINS  ie: PTOTEMOE0027
It does work...
* ISIN code: PTOTEMOE0027
* Converted to digits: 2529242914222414002
* Split into two groups: 2222122102 & 594942440
* Multiply group containing rightmost character: 4444244204 & 594942440
* Sum of digits: 73
* Modulo 10: 3
* 10's complement: 7
* Modulo 10: 7
Which correctly matches the check digit.

thread_title:  History of ISINs 

message: Counterpoint to the above;
To be accurate, ISIN is not free and open, and almost no ISO standard is made to be free and open.  Some ISO standards are offered by their RA or MA as free and open.  But ISO maintains rights for Intellectual Property on all ISO standards, and advocates cost recovery and RAND principles around those standards.  Further, access to ISO standards library is one of the funding points for ISO.  This is not an indictment, simply a statement.  To say ISIN is open source is highly inaccurate.  Free use is not uniform, even removing consideration of S&P issues.  'Competition' is perspective-based.  Is there competition for issuance of ISIN? No.  Are there multiple methodologies for identification of securities and financial instruments apart from using an ISIN? Yes, there are. Rcr203 (talk) 15:57, 30 June 2016 (UTC)

message: As per the above section...
* This page is undergoing persistent vandalism from someone that is removing good links and replacing them with a link to a clickbait site.
* The vandal uses anonymous IP accounts and single-use named accounts, so semi-protection will be an effective block.
* I have left messages on the talk pages of various of the accounts used (assuming good faith at first) and have no response from any of them.
* Given the slow speed of the edit war (typically once a day, as per the table of diffs above), I request a one-week semi-protection (one day will essentially have no effect).
* There are currently few other edits to this article other than the edit war, so semi-protection will not be blocking good edits.

message: From the following paragraph from the example it says:
Collect odd and even characters:
3028037833100 = (3, 2, 0, 7, 3, 1, 0), (0, 8, 3, 8, 3, 0)
From this it could be interpreted that the characters is split on wheter they are odd or even. Not that the position of the number is odd or even.
So to avoid confuision this should be changed?

message: "BAE Systems: ISIN GB0002634946, expanded from SEDOL 000263494

This sound like "000263494" is the SEDOL of BAE Systems, but it is only "0263494". Perhaps it make sense to clarify this.  — Preceding unsigned comment added by 31.16.186.222 (talk) 13:27, 18 November 2022 (UTC)

message: "ISINs consist of two alphabetic characters, which are the ISO 3166-1 alpha-2 code for the issuing country, ... "
This statement is not necessarily true. E.g. Lookup ISINs starting with XS , when XS is not a valid iso2a country code.
Shall we edit the text accordingly ?
