As it shows that all projects of GF180-MPW0 are shipped, where can I get my tracking-id-number? Are the chips delivered by FedEx?

Yes, they are delivered by FedEx. You should have received an e-mail from trackingupdates@fedex.com (or your country-specific @fedex.com address) to the e-mail address you entered in the shipping details.

But I didn't received an email until now, maybe a few days I should wait for.

I had not received such email also. May be it is possible to get a tracking number from Efabless?
