Card account number

Any customer can have more than one card account number (e.g. for individual invoices) under which other names are also listed (e.g. for additional cards bearing the name of the customer’s partner). The card account number appears on every invoice or in your "one" account under “Invoices”. It always begins with the numbers “110” and comprises 16 digits in total. You do not need to enter your card account number when logging in to "one". Please note: Your card account number is not the same as your credit card number.
