I thought someone way up-thread said there is a way to find out your plates, even before they arrive. Maybe AAA can find that info for you?
Once you have the assigned plate number, you can apply for stickers.
If however, you want to transfer personalized plates over, you have 2 choices:
1) Transfer the plates over, then apply for HOV stickers. A longer wait for sure. If AAA transfers it, there is little delay.
2) Apply for the HOV stickers, then transfer the plates over after you get them. You do not need to reapply for HOV stickers. Yes, you are supposed to, but I see no need. Even though they are tied to your plate, they are also tied to your VIN. No CHP officer will ever give two s**ts about it. If I am wrong about that, no, I will not pay your fine
