If your Fiscal Number is not accepted during registration, please make sure that you are using the 9-digit number that has been issued to you by the Dutch Tax Authority (Belastingdienst). Please check any letters you have received from the Belastingdienst in order to locate this number.
If you are sure that your Fiscal Number is correct, please contact the Service Desk for further assistance. If your organisation had previously been registered with the Chamber of Commerce (KVK), but has now been designated with a Fiscal Number, please make sure to specify this information to the Service Desk, as an alternative is available in this instance.
