I just purchased the i1Display Pro and installed it on my computer tonight (1/10/14).
The serial number
+Serial Number Location for i1Display Pro and ColorMunki Display
The instrument's serial number for the i1Display Pro and the ColorMunki Display is located on the sticker on the permanently attached counter weight. The ColorMunki Display's serial number begins with "CM..." whereas the i1Display Pro begins with "i1...".
Open i1Profiler with the instrument plugged into the USB port. Open "Licensing" in the lower portion of the home screen and then select "Registration". Click on "Phone Registration" to display the instrument's serial number.
Once i found this info from some extensive web searches I was able to successfully register my device
