I too have a tracking number that also doesn't show up in DHL's system.
Glad I am not the only one. Although this does make me nervous. Its been a whole day sense I got the # and its still not active. Although I have had this happen before with UPS and FedEx I have never experienced DHL before.
There was someone else that posted there DHL tracking number here on like page:
I wonder how long it took for this # to become active. Sadly that was in a different country and I can only hope for a similar experience here. Because if thats the case then we are getting are shipment this week.
