Many banks use a central processing depot for their BACS and other transactions. Therefore a BACS check on a specific sort code may return the bank's central depot rather than the specific branch address.
This field contains more detail about the outcome of the validation process and describes reasons why validation failed or changes made to pass validation. ‘DetailsChanged’ indicates that the account and sort code should be changed for BACs submission (check ‘CorrectedAccountNumber’ and ‘CorrectedSortCode'). ‘CautiousOK’ is set where the sort code exists but no validation rules are set for the bank (very rare).
No, our system does not contain information on individual accounts, only rules that allow us to confirm whether the structure of an account number fits the sort code. Therefore, you will only ever receive information back regarding the sort code, with a confirmation against whether the account number would fit with that sort code.
