We received the following warning in the clearance response for one of our invoices:

BR-KSA-100 - The Buyer VAT Registration Number (BT-48) is missing or invalid. Please verify the Buyer VAT Registration Number (BT-48).

The response also indicates:

clearanceStatus: CLEARED

We would appreciate your clarification on the following:

  1. Does this warning have any impact on the validity of the invoice?
  2. Can you please confirm that the invoice has been successfully submitted, cleared, and accepted by ZATCA despite this warning?
  3. Is any further action required from our side regarding the Buyer VAT Registration Number (BT-48)?
