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'

There are three types of 'PO numbers', based on the following principles:

  • WxxFxx-xx (Property number)

  • WxxLxx-xx-xx (Lease number)

  • WxxSxxxxxxxx (Case number)

The three types are used in the following configurations:
