message: This page: http://www.precisonline.com/ccvalidate.js.html seems to indicate that Diners can also start with 36 38 and 300-305.  - mgolden July 24, 2006
The "Diners Club US & Canada[5]" overlaps with the Mastercard range, both of which are 16 digits, starting with '55'. I suspect the Diners Club is wrong (unless their cards are supplied by Mastercard?)
I believe that MasterCard bought this part of the Diners business, but that there may still be some "Diners" cards within this sequence, however operated by MasterCard.  —BozoTheScary 21:35, 19 July 2007 (UTC)

message: Why is the title of this article "Credit card number" when it also talks about debit card numbers? (Stefan2 00:20, 7 June 2007 (UTC)
replies: text: That's a good question.  Likely, part of the reason is that the debit cards use credit card conventions, like the Luhn algorithm.  There may also be some similarities in the underlying transaction systems.  Feel free to suggest a more accurate name.  —BozoTheScary 01:58, 7 June 2007 (UTC)

text: The point that you bring up is interesting, however both cards function differently, as do bank cards and other credit society card numbers. I think it would be more pertinent to merge the details with BIN as already suggested and list the different types of cards under BIN with links to the different card types.

message: Does anyone know whether MasterCard intends to standardise the format of Maestro card numbers, which currently come in at least two forms?  Currently (here in UK) some have 18 digits and use a 1 or 2 digit issue number as part of the verification process.  Others (mainly from the Royal Bank of Scotland Group) have a 16 digit number and use a start date as part of the verification process, though the actual verification of start dates is not as strict as with issue numbers.  I'm wondering, will either of these formats become standard? And why don't they just use the same items for verification as VISA, VISA Delta, and MasterCard cards do?--PeterR (talk) 19:37, 13 December 2007 (UTC)

I found out about this while trying to research China UnionPay characteristics.  It also appears that 1800 and 2131 for JCB are obsolete, and there may be a new range in the 3x area which I'm trying to get confirmation and a published source for. 69.159.230.251 (talk) 01:27, 3 September 2008 (UTC)

That said, I imagine most gateways would have at least a rudimentary amount of fraud prevention that would at least filter out commonly-used test numbers, so I'm surprised it worked. --Sydius (talk) 16:44, 25 September 2008 (UTC)

message: Both my a few old Barclay Visa (which I've had for about 10 Years with this number) and the new one after changing the card type start with "4906 38" (also my brothers Barclay Visa card) so I'd assume this is the prefix for barclays bank plc cards. 
My japanese ebank (Debit) Visa starts with 4542.
My old Barclay Mastercard starts with 54. As far as I know Barclays Bank PLC is a british credit card firm, so the assertion "Cards issued in Canada and the USA start with 54 or 55 and are treated as MasterCards worldwide. International cards use the 36 prefix and are treated as MasterCards in Canada and the US, but are treated as Diner's Club cards elsewhere." seems to be incorrect.

# the chart is missing 2 of the ranges for "CUP"
# the chart has no rows for 18 or 19 digits
# the chart contains the IIN named "RUA CARD" which is not in the table
# the chart is missing "Lasr"
# the chart is missing "DC-UP" which would be difficult to put in the chart because it overlaps with MasterCard
# the JCB range in the chart does not match the range in the table
# the DISC range in the chart is wrong

replies: text: Let me guess, you have an EC Maestro card issued by a German bank. The 10-digit "Kartennummer" printed on the front of the card is NOT the actual Maestro card number, but some random number assigned by the bank. On German Maestro cards, the actual 19-digit girocard/Maestro card number used for payments is not printed anywhere on the card (for security reasons, in order to prevent users from using the card on the internet), but only stored on the magnetic stripe and inside the chip. The number is 19 digits (in the format 672BBBBBAAAAAAAAAAL) and, for German cards, always starts 672. B is the shortened bank sort code of the issuing bank, A is the account number ("Kontonummer" on the front of the card) and L is the Luhn check digit. 93.129.197.8 (talk) 00:55, 2 September 2012 (UTC)

message: The statement in the body of the article :-
[quote]
A search on Visa's web site results in many references to card numbers being 16 digits long. However, searching for references to 13-digit cards will turn up no results.[original research?] All 13-digit account numbers have since been migrated to 16-digit account numbers.
[/quote]
is totally wrong.  There are today (11-12-13) 479 account ranges defined by Visa that can use 13-digit PANs.  They are, slowly, being migrated to 16 digit numbers but this can and will take years.  Also, as the issuers migrate, the new PANs will usually not be the old PAN with 3 digits inserted as suggested in the next paragraph.  — Preceding unsigned comment added by 87.74.76.49 (talk) 18:58, 11 December 2013 (UTC)

message: The article talks about "six-digit" IIN numbers, then goes on to show a table consisting almost entirely of not-six-digit IIN ranges. So is it not six digits, or are all the table ranges wrong? These can't both be correct. --74.88.34.126 (talk) 01:00, 7 September 2016 (UTC)
replies: text: At the time the above comment was written, the fact that IIN ranges were sometimes expressed with fewer than 6 digits was merely a matter of how to interpret such ranges.  As an example, the range "300-305" means 300000 to 305999.  So setting that issue aside, we have one section which says that the IIN is 6 digits long, and the following section claiming that it's 8 digits long.  In fact, there is a transition from 6 digits to 8 digits that's taking place, and that needs to be explained.  The transition is quite a bit confusing, I think this would probably merit its own section.  Fabrickator (talk) 20:11, 13 August 2019 (UTC)

text: It's also an issue in this section under "Structure": "The leading six or eight digits (one or up to eleven digits) are the issuer identification number (IIN)". So they are both 6-8 and 1-11 digits long? How does that work?  — Preceding unsigned comment added by 2A02:8388:8CBB:3100:841A:8303:7837:478E (talk) 12:11, 3 November 2023 (UTC)
