One touch platinum serial number location

[Easy]

I am going to look at one of these and was wondering where I would look for the serial number if I bought it and wanted to register it.
Thanks a head of time.

No SN on these just the date code on the vents.

If you have trouble registering it on Weber's site, call Customer Service - they should be able to help you. I had to do that with a platinum I picked up a few weeks ago.
