@joker I am looking into adding a check for IBAN codes in Verify.
- space characters are ignored.
- the country code and code length for that country are checked.
- the checksum is checked.
- all letters are expected to be upper case if case sensitive is checked.
So these are all valid:
GB82 WEST 1234 5698 7654 32
IE64 IRCE 9205 0112 3456 78
BI1320001100010000123456789
GB29NWBK60161331926819
FR1420041010050500013M02606
DE89370400440532013000
And these are valid if case sensitive is not checked.
gb82 WEST 1234 5698 7654 32
GB82 west1234 5698 7654 32
If you have some test data, please feel free to send it to us. Please make clear whether you think the values should be valid or invalid.
