Bank and accounts
The account is checked together with the BIC: the account’s check digit depends on the bank.
The check finds typos in a number. It does not know whether such an organisation or account exists. The calculation runs in your browser: nothing is sent to the server or stored anywhere.
How to use it
Paste or type the number into the relevant field. Any field can be checked separately.
To check a current or correspondent account, also enter the bank’s BIC.
The result appears under the field: the number is correct, or it contains a typo.
