EAN numbers

DTU's EAN numbers are used as electronic invoice addresses. Suppliers must use the correct EAN number to ensure that the invoice is received in the right place in DTU's systems and can be processed and paid on time. Here you can find DTU's EAN numbers and guidance on how to handle situations where an incorrect EAN number has been used.

How are EAN numbers used at DTU?

At DTU, EAN numbers function as electronic addresses in our invoice system, where different departments and units may each have their own EAN number.

When a supplier sends an electronic invoice to DTU, they include an EAN number so that the invoice is automatically routed to the correct unit and to the person responsible for approving it.

If the supplier uses an incorrect EAN number, the invoice may be sent to the wrong place or become stuck in the invoice workflow, which may delay payment.

Typical signs of an incorrect EAN number 

  • The invoice cannot be found in the system
  • The invoice has been sent to the wrong unit
  • You or a colleague receive a reminder for an invoice you do not recognise

In these cases, the EAN number is often the cause.

If a supplier needs to send an invoice, or if an incorrect EAN number has been used, you can find the correct EAN number in the list here

If an EAN number is incorrect

Below you will find guidance on how to create or update EAN numbers, as well as what to do if an EAN number has been entered incorrectly.

It is an international numbering system that, in Denmark, is used in the public sector as digital addresses for electronic invoicing. An EAN number consists of 13 digits, is unique to each unit, and is used by suppliers to ensure that electronic invoices are sent correctly.

Creditor and Bookkeeping are responsible for creating new and updating existing EAN numbers. Requests must be submitted by a department secretary or a designated person from the unit.

When creating a new EAN number, the following information must be provided:

  • Name of the department or unit
  • Location number
    DTU's internal unit number used in the financial system
  • Contact person (name, phone number and email)
    Administrative contact in the unit (e.g. department secretary or finance staff)
  • First recipient in the invoice workflow
    The person who will receive the invoice if the system cannot identify the stated requisitioner
  • P-number and official address
    Production unit number linked to a physical address (CVR registration) and the official DTU postal address for the unit
  • If the invoice has been issued to DTU, it should not be credited.
  • The invoice recipient must contact the supplier to clarify the correct EAN number and recipient, and then forward this information to AOR-fakturabehandling@dtu.dk.
  • Creditors and Bookkeeping will use this information to correct the EAN number so that the invoice is routed correctly in the system, appears correctly in reports and does not result in reminders being sent to the wrong recipient.
