Italian IBAN format

[Stefan Rijnhart (Opener)]

Hi,

an Italian IBAN we encountered suggested that the expected formatting for this country's IBAN in sepa/iban.py is incorrect. The current format is specified as 'WBBBBBCCCCCCAAAAAAAAAAAAV'.

The IBAN in our data parses correctly against 'WBBBBBCCCCCAAAAAAAAAAAA'. This corresponds to the formatting mentioned on http://en.wikipedia.org/wiki/International_Bank_Account_Number,
'KAAAAABBBBBCCCCCCCCCCCC'.

Cheers,
Stefan.

I've tested this format against a valid IBAN code and this does not work. It is not ignoring the first 4 characters (IT**) and so it is parsing the string incorrectly.

Hi James,

thank you for testing.

Cheers,
Stefan.

Hi James, thanks for reporting.

Although James could not validate the solution I suggested, I privately received the account number that he tried to validate and my suggestion does seem to do the trick.

Pieter, note that your modification to the Italian BBAN format in http://bazaar.launchpad.net/~pieterj/account-banking/5.0/revision/71#account_banking/sepa/iban.py is different from my suggestion and still gives the following error validating Italian IBANs:

account_banking/sepa/iban.py", line 131, in __extract__
    result += value[i+4]
IndexError: string index out of range

The reason for this is that the branch number is still 1 character too long.
