Guidelines on the use of project numbers and cost center codes

4 June 2026

We would like to draw your attention to an important guideline regarding the use of project numbers and/or cost center codes (kostenplaatscodes)

When placing an order with a supplier, entering an order in the ordering system, or submitting an expense claim, it is important to first determine whether it concerns a project or not.

  1. If it concerns a project
    Only the project number needs to be stated. This applies to:
    • Vidatum project numbers including the suffix -01
    • Project numbers starting with 1002P, 1003P, 1004P, or 1005P

Please note: for Vidatum project numbers, the suffix -01 is mandatory.

  1. If it does not concern a project
    Please state the appropriate cost center code.

If you have any doubts or questions, please contact Finance or Project Control via financearch@arch.leidenuniv.nl.
