Please beware! Aarhus University is currently experiencing attempts of fraud using fake invoices that are copies of invoices from suppliers.
Therefore, be aware of inquiries from individuals posing as AU employees with similar-looking email addresses, requesting copies of outstanding invoices issued by the supplier to AU. Do not send anything without verifying the identity and e-mail of the sender beforehand, as it may be a scam. We therefore encourage suppliers to check the email address’ authenticity with a simple Google search or on our Contact information website should you experience this.

The address of delivery can perfectly well differ from the billing address.
