==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:
# 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 

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:

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

Read:

<em>ISINs are created only for EQUITIES, and not derivatives such as options or futures.</em>

Since technically options and futures ARE securities?

See [[Security (finance)]]
<blockquote>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. <b>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."</b> 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".

Haaaaa, laughabale. All these national numbering agencies makes millions of dollars yearly and try and keep anyone they can out, all in the name of 'this is not a real website' or 'that group is not a member of that agency (meaning a member of the monopoly). Disgusting. CUSIP makes everyone pay for data usage including ISIN CODES from the US that incorporation the CUSIP number!!!! They are not ever free.

The ISIN is just a number that identifies a security. [[Securities Act of 1933#Regulation S|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.

== What does "rightmost character" mean!? ==

I don't really understand, what "rightmost character" means!? Can anybody explain it? The examples don't help me. --[[Special:Contributions/91.53.29.217|91.53.29.217]] ([[User talk: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.

== Removing a space ==

Hello. I have been repetitively removing a single space in the article, in a three-quote, the rendered a bad formatting. Each time I have been reverted because of "spamming". I would like to discuss here the definition of spamming that could apply to removing a single space. Thank you. [[User:Kiwipidae|Kiwipidae]] ([[User talk:Kiwipidae|talk]]) 17:24, 18 May 2016 (UTC)
: E.g. [https://en.wikipedia.org/w/index.php?title=International_Securities_Identification_Number&diff=720901955&oldid=720901514 one of the edits removing a space]

== Commercial Model and Controversy==

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. [[User:Rcr203|Rcr203]] ([[User talk:Rcr203|talk]]) 15:57, 30 June 2016 (UTC)

== Multiply redundant definitions of securities which may carry an ISIN ==

The article currently appears to define which securities ISINs apply to in 3 different places, using 3 different descriptions!

Paragraph 1: bonds, commercial paper, stocks and warrants<br/>
Paragraph 2: debt securities, shares, options, derivatives and futures<br/>
Description section: equities, debts, ETFs, options, derivatives, and futures<br/>

I recently edited "debts" to "bonds" but this was reverted. I happen to think I was right, since "debts" in this context is both mangled English and risks referring to non-securities such as bank loans. However, I do not have sight of a copy of ISO 6166, so if someone who does have access to the English version would like to consolidate these definitions in one place in the article, using the actual language of the standard, that would be hugely appreciated. Thanks. [[User:CharlesSpencer|CharlesSpencer]] ([[User talk:CharlesSpencer|talk]]) 18:13, 26 June 2017 (UTC)

: Wow; I didn't expect an ISO standard to cost so much. The current latest edition, [https://www.iso.org/standard/44811.html ISO 6166:2013], is priced at CHF 58. Instead I found a free copy of an older edition, [http://www.sdc.com.jo/arabic/images/stories/pdf/iso_6166_2001_.pdf ISA 6166:2001], which I imagine is sufficient. Annex B ("Competence of numbering agencies") on pages 6-7 lists the following asset types:
:* Equities (shares, units, depository receipts)
:* Debt instruments (bonds and debt instruments other than international, international bonds and debt instruments, stripped coupons and principal, treasury bills, others)
:* Entitlements (rights, warrants)
:* Derivatives (options, futures)
:* Others (commodities, currencies, indices, interest rates)
: As expected, that's a wide scope. Hopefully that's enough information for you. In particular, I see that "debt" is indeed the language of the ISO and encompasses bonds. The wording most in keeping with (certainly this edition of) the standard is "securities and other financial instruments (including equities, debt instruments, entitlements, derivatives, and others)". -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 18:46, 2 July 2017 (UTC)
::I absolutely agree - that price was what made me ask someone who had already spent that much to help!!! Thank you for your clarification. "Debt instrument" I have no problems with, because the word "instrument" goes to "security" (i.e. transferable). Just saying "debt" or worse yet "debts" on its own could, in technical English, theoretically encompass debts in non-securities form such as bank loans, which do NOT carry ISINs! Thanks again.

== Request for Help ==

{{Help me-helped}}
I'm having some difficulty on this article ([[International Securities Identification Number]]) where, in my opinion, good content is being removed (and replaced with a clickbait link). It's a slow process, with edits happening over days rather than minutes, but it still feels like an edit war to me. I'm currently reverting each time, and it feels like I'm crossing into 3RR territory (in spirit, since these are not within 24 hour periods).

I've tried reaching out to the offending user(s) via their talk pages but have had no response. I'm too close to this incident to make the call on whether this is ''clearly'' vandalism, and the slow speed of the war means it doesn't hit the normal thresholds for 3RR or semi-protection, so a request for help from experienced editors seems the appropriate thing for me to do. And I don't know whether this specifically needs an administrator to weigh in, hence I haven't used the [[Template:Admin help|Admin help]] template.

=== Phase 1 ===
In this first phase, following [[Talk:International Securities Identification Number#Multiply redundant definitions of securities which may carry an ISIN|conversation on the article's talk page]] above, user [[User:CharlesSpencer|CharlesSpencer]] made revisions to improve the article (supported by information that I provided).

Thanks for reading! -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 12:28, 1 September 2017 (UTC)

:Hey [[User:Stelio|Stelio]]. I'm definitely not an expert on the subject of the article, and you are right to be more concerned about the spirit of 3RR than the letter, not for the reason of sanctions, but for the reason of building a better encyclopedia. You seem to make a fairly convincing argument that these are not well-intentioned edits. I don't think anyone is going to be too terribly harsh on you for the whole thing. But it's probably way too slow-motion of an edit war to justify asking for page protection.

:I would recommend you drop some notes on the talk page of the user next time they come around. Sometimes the easiest way to convince someone to stop being disruptive is to show them why they're being disruptive, rather than them apparently just visiting the article every so often, and seeing that their contributions have been reverted. Gotta keep in mind that a lot of new users don't even realize that talk pages exist in the first place.

:: Thank you for the comment. Agreed that semi-protection doesn't feel right for a war of this speed. But I've tried reaching out via user talk pages and have had no response. Attempts: [[User talk:107.77.205.129|[1]]] [[User talk:2600:387:4:803:0:0:0:AD|[2]]] [[User talk:97.113.83.212|[3]]] [[User talk:71.231.81.222|[4]]]. The shifting of IP addresses and the creation of a named user account for the sole purpose (so far) of a single one of these edits makes me feel like there will be no response in the future either.
:: I'll keep patrolling the page, reverting the disruptive edits, and posting again on whichever new IP address user page pops up next time. -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 16:50, 1 September 2017 (UTC)
:::I've also added it to my watchlist. So I'll try to keep an eye out.

Thanks, Timothy! (Also, new entry added to the table above for the latest new single-use account, [[User:TimothyMirr|TimothyMirr]].) -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 10:21, 4 September 2017 (UTC)
Updated table again. -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 08:59, 7 September 2017 (UTC)
Ha! The latest IP vandalism had the temerity to repeat my edit description of "restoring good content as per talk page". I note with interest that user 66.192.186.210 has ''not'' discussed this on the talk page. -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 19:54, 7 September 2017 (UTC)
More. -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 19:15, 8 September 2017 (UTC)
With the latest named account (that is a profane personal attack) it's clearly vandalism. I'll request semi-protection. -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 20:03, 10 September 2017 (UTC)

== Semi-protection request ==

As per [[#Request for Help|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.
Thanks. -[[User:Stelio|Stelio]] ([[User talk:Stelio|talk]]) 20:15, 10 September 2017 (UTC)

== Confusing example ==

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?

==Misleading comment==
"BAE Systems: ISIN GB0002634946, expanded from SEDOL 000263494
The main body is the SEDOL, padded on the front with the addition of two zeros."

This sound like "000263494" is the SEDOL of BAE Systems, but it is only "0263494". Perhaps it make sense to clarify this.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/31.16.186.222|31.16.186.222]] ([[User talk:31.16.186.222#top|talk]]) 13:27, 18 November 2022 (UTC)</small> <!--Autosigned by SineBot-->

== First two characters of ISIN need not be ISO 3166-1 alpha-2 ==

"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 ?
