Valid UK IBAN rejected - Githubissues

AAtticus commented 11 years ago

My client has a UK IBAN that looks like

GB70 HLFX 1234 1234 1234 57

This is a valid IBAN code but gets rejected by the Iban Validator.

I just added more tests for international IBAN numbers and can confirm that the validator fails for UK/GB IBANs. Only for UK/GB that is. Strange indeed. I (or somebody else) will have to take a look at this.

Interestingely, it also fails in a British IBAN validator … http://www.paymentscouncil.org.uk/resources_and_publications/iban_checker/ GB29RBOS60161331926819

However, these work (found them online): GB 12 CPBK 0892 9965 0449 91 GB 29 NWBK 6016 1331 9268 19

The second one looks exactly like the example above, except for the 4-letter bank code. So maybe we are just falling for actually wrong IBANs?

@AAtticus Can you post the exact IBAN of your client for test purposes? If you prefer you can email it to me, I will keep it confidential: manu at sprain.ch

I checked with a bunch of UK IBANs I found online and also with some real life examples from a friend. They all validated as expected. So there is no issue.

I see two reasons for the confusion:

http://www.rbs.co.uk actually posted a wrong example on the example list. GB 29 RBOS 6016 1331 9268 19 looks exactly the same as GB 29 NWBK 6016 1331 9268 19 which can be found on many other lists except for the 4-letter bank code. The bank probably just changed this part - and therefore the number doesn't validate anymore as the checksum doesn't match.
The customer of @AAtticus supposedly has been using an invalid IBAN. I'm sorry, but it is the only explanation I have.

So I am closing this as a non-issue. But at least we have more tests now for proof.
