Do I have to enter a DUNS number for my company?
No. This is an optional field. You are only required to fill in the fields marked with an asterisk (*). If you enter a DUNS number and you get a message that it's already in use, leave it blank.
DUNS numbers must be unique within the Ariba Commerce Cloud. Your company can have multiple accounts on the Ariba Commerce Cloud but only one account can use the DUNS number.
