Called both DMV 800 Number and the HOV sticker Special Processing Unit 916 area code number. I was suggested to go to DMV and surrender my plate and get a replacement, and I was also told that right now only about 3,300 HOV stickers availabile for Jan 2nd, 2007!!!

I was amazed how amazing technology has brought efficiency to DMV. Checked a few DMV around my neighborhood and went to the one that has the shortest wait-time. Got my replacement plate and mailed in my application for sticker the same day via USPS Express Mail (FedEx and UPS won't deliver to P.O. Box). I am going to contact Special Processing Unit next Wednesday if by that time my check has not been cashed out.
