Talk:International Securities Identification Number

Commercial Model and Controversy

I have added these sections to allow insight into how the commercials around issuance and distribution world. Someone is posting commercial links which are contrary to the open source emthodology with which the ISIN was constructed and the free use (except S&P issued ISINs) of the ISIN. A lot of people give up a lot of time unpaid to maintain this. Please do not post adverts to services which pose as a viable competitors to NNAs or ANNA as there is not competition in this area and to claim there is is simply misleading and a lie. — Preceding unsigned comment added by Rgnewbury (talk • contribs) 17:35, 25 March 2015 (UTC)

The VB code appears to be right, but the descriptions forget the reverse the string step

Either than or the examples are all wrong, we don't need the reverse the string step. Anyway it's a little foobar, needs some work. —Preceding unsigned comment added by 192.165.213.18 (talk) 10:33, 23 July 2010 (UTC)

Could someone please move this page to reflect the correct title

According to ISO 6166:2001 this system it is "Identification Number" not "Identifying Number"

ISIN and CUSIP difference

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:

1. The letters are converted to digits (becoming two seperate digits)
2. The numbers are split into two groups
3. The digits from one group (the one which contains the right most character) are multiplied by two
4. The digits are summed
5. etc

In CUSIP:

1. The characters are split into two groups
2. The digits from one group (the one which contains the right most character) are multiplied by two (letters being converted to numbers before multiplying)
3. The digits are summed
4. 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

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

Should it not be equities instead of securities

Shouldn't this sentence:

ISINs are created only for securities, and not derivatives such as options or futures.

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.

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)

Freely available?

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)

How to obtain a ISIN code for a soon to be listed securities?

How to obtain a ISIN code for a soon to be listed securities? —The preceding unsigned comment was added by 203.117.169.51 (talk) 04:28, 15 February 2007 (UTC).

In the UK the London Stock Exchange will issue ISIN's for securitites and in Switzerland it is done by SIX Telekurs AG.

Please make it available to.....

I tried to search the string on the main page as 'International Securities Identification Number' and it doesn't redirect to the page of International Securities Identifying Number. According to the info at http://www.iso.org/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=33446&ICS1=3&ICS2=60&ICS3=&scopelist=

My preference as above should also be valid —The preceding unsigned comment was added by 72.52.66.10 (talk) 10:43, 16 April 2007 (UTC).

Well... now it does. You could have done it yourself you know. Rob cowie 19:13, 21 September 2007 (UTC)

REG-S and 144 A ISINs

Please brief about types of ISINs as well like REG s and 144 A ISINs. What type of ISINs are they? can any one security has both type of ISINs and some more....?? —Preceding unsigned comment added by 220.227.149.35 (talk) 07:56, 7 January 2008 (UTC)

The ISIN is just a number that identifies a security. Regulation S bonds get a common code and an ISIN and are generally accepted for clearance through systems outside the US. 144-A bonds get a CUSIP number and an ISIN and are generally accepted for clearance through The Depository Trust Company (DTC) system. See [1].Paul Foxworthy (talk) 07:36, 17 July 2015 (UTC)

The relation with the FIX Protocol could be stated as thus :

The SecurityID Field(48) specifies an ISIN number when the ID source Field(22) is equal to 4 : 22=4 48=ISIN samusz (talk) 09:29, 24 July 2008 (UTC) 09:12, 24 July 2008 (UTC)

PTOTEMOE0027

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. -Stelio (talk) 17:39, 25 March 2014 (UTC)

What does "rightmost character" mean!?

I don't really understand, what "rightmost character" means!? Can anybody explain it? The examples don't help me. --91.53.29.217 (talk) 10:31, 9 May 2015 (UTC)

- The rightmost character is the last character at the right hand end of the string. It's more to the right than any other, so the most right. The checksum algorithm splits characters in the string into two groups: odd and even. The rightmost character might be in either the odd group or the even group, depending on the length of the string. It's always the group that contains the rightmost character that is doubled. Another way to look at it is you start from the rightmost character and work backwards towards the beginning of the string, doubling every second character.

Proposed merge

I can't see any other discussion but would strongly support merging the ISO article in here. They are essentially the same subject Chrismorey (talk) 06:11, 17 July 2015 (UTC)

I agree Paul Foxworthy (talk) 07:22, 17 July 2015 (UTC)

I support the merge. JDAWiseman (talk) 23:00, 15 November 2015 (UTC)

History of ISINs

Please could somebody who knows the history add a summary of it, even if only to say when ISINs started. JDAWiseman (talk) 23:02, 15 November 2015 (UTC)

Agreed and done. Sargdub (talk) 08:17, 29 January 2016 (UTC)
