PO number

Electronic invoices and credit notes sent to DEAS must include a PO number. The number will guide your invoice to the right person at DEAS, who must confirm that the service was received.

If you enter the wrong number, your invoice may be rejected by our invoice system. For this reason, it is important that you, the supplier, ensure that you have the right PO number.

PO numbers for the claimants

The claimant, i.e. the person who commissioned the good/service, should give you the correct PO number.

If you are in doubt about the number, you should contact the claimant.

Three types of 'PO numbers'

The PO number always starts with 'W' (workflow number) as well as a number indicating the type of service provided.

Then either F, L or S follows as well as a number:

  • WxxFxx-xx (property number)
  • WxxLxx-xx-xx (property number and lease number)
  • WxxSxxxxxxxx (case number e.g. construction og insurance case)

The typical PO number is used in the following compositions:
