What is the KID number?

The KID (Kunde ID) is a customer identification number that is mandatory for invoices in Norway. The KID provides a payment reference to the vendor and ensures that the vendor is posting the payment correctly.

If you are based in Norway, you will see the Payment Note as required when invoicing. This field is located under the Additional Fields section and it's where you have to insert your KID number.
