Letters
If you want to send a standard letter by regular mail, you can put it at the Reception on the ground floor. Make sure that you affix the Observatory barcode and return address on the backside and write receiver's address in the middle on the front of your letter. Stickers can be collected at the Secretariat.
Would you like to send out registered letters? Please write down 'per aangetekend' and telephone number on the envelope for internal use.
Packages
If you need to send a package by courier, contact the Secretariat. Make sure you have a SAP number for the costs involved. Packages should be put at the 'Expeditie' (suppliers' entrance GM.0.04), not the Reception.
You can contact Nancy Zhou for sending out posts secretaries@strw.leidenuniv.nl.
