support for country specific check digit #46
Comments
Hi there. I would love to add support for grabbing this, but we need more information than one country to make an informed design. I mean, who knows, some countries might have two BBAN-based checksums! Unfortunately it seems Wikipedia is not really a valid source for this stuff, it's as good as hearsay until there's an official document, but it's a good starting point. Since the implementation will therefore probably follow a "country-specific validation" path once documents are dug up, I feel like #40 is perhaps a better description of the same issue and this issue is almost a duplicate. May I ask why you want the BBAN check digits? May I ask if you have the algorithm for the checksum? May I ask if you would like to volunteer to do country-specific research on additional countries with BBANs that incorporate national checksum systems? There may also be similar checksum systems at the bank level in some countries... |
Actually #39 is closest. |
Searching the Wikipedia country-specific data, it is really untrustworthy. For example look at Bosnia and Herzegovina, it says the IBAN checksum is "always 39". What? This is just garbage. We need real references. I believe your data on Spain, but I would prefer to have some additional countries official data before starting out. Therefore I am going to close this issue as duplicate and use #39 to request country info, please feel free to post country-specific info there, and when we have 3 or more I will be happy to add the feature. |
Hello, I'm glad to see that the library is receiving support again.
I don't know if within the new features (or the future ones) is included a new function/method to get the country specific check digit.
In the case of Spain:
The format of the iban is: ESkk bbbb gggg xxcc cccc cccc
where:
k = IBAN control digit
b = National bank code
g = Branch code
x = Check digits
c = Account number
