That does not look like EMS to me.
L stands for letter.
EMS tracking numbers should start with an E.
If you download the iOS app Parcel (4 free, but only allows to track 3 packages at a time) you can see who the carrier is:

EDIT: Referring to the newest update posted by Candurin (thank you by the way

).
Next tuesday? A friend of mine still has no tracking number and he filled in everything correctly. He is not very happy now. They will send it on the 22nd of September. Ordering from Amazon.com will probably be faster. And he contacted them long time ago before all the delays.
