who has green sticker with number higher than 40,000 in CA?

Check this thread:

Has anyone received a CA Green HOV Sticker yet? | PriusChat

The numbers go higher than 40k because of replacement stickers.

Also, if you ever find yourself on Jeopardy, the stickers actually started at #0. So if there were no replacements, the last sticker would've been #39999.

 

Sorry bud, but as of this time you are SOL. Stickers have officially hit 40k: "As of May 9, 2014, 40,000 "green" stickers have been issued." The numbers above 40k are due to reissues (stickers falling of/ being stolen/ etc), not due to them giving out 40k stickers.

However, you might have a tiny bit of light, as there is legislation to bump the number to 85k, but it hasn't been fully passed yet:
AB 2013 - California 2013-2014 Regular Session - Open States

 

They had a program where they allowed dealerships to preorder stickers to help facilitate drivers being able to have them the day they bought them instead of having to wait a few weeks. Hence a few dealerships still have some cars with stickers on hand. However, as to applying to the DMV if you didn't buy one with the stickers already allocated for it, no luck. Sorry about your timing, but the PiP is still a great car!

 

It seems like it's got a pretty good chance of getting passed. Obviously current sticker owners are against it as carpool lanes already are almost clogged to the point of being regular lanes, but the auto industry is pushing it to help sell plug-in hybrids (Toyota's PiP, Ford's Energi line, BMW's i3 REx, Chevy's Volt).

 

According to the AB2013 bill history, the clean air stickers do not have a significant effect on HOV lane congestion:

 

Hopefully you got a great price on the PiP. The other CA buyer's remorse we heard was few regular Prius buyers not realizing how low cost PiP was after Fed+CA incentive$ ($4000 off). They would have got the PiP.

CA PHEV market is really dynamic right now with the green sticker expiration. You could contact Dianne Whitmire here to see if you have any options. Last I heard, she has some green sticker PiPs for sale I think mostly the Advanced PiPA. Had you gotten a green stickered PiP at the last minute, you would have paid a premium for that. So where you hopefully are is, you paid relatively low price for a PiP and if stickers come back you will be lucky, but you will have saved some money. If top proirity is green sticker, see if there is some way swing a fast deal for a PiPA on the lot with a sticker.
