He's talking about your car's registration. Ask DMV if your registration is under processing. If it is, you can fill in the HOV sticker application based on your VIN and not worry about it being rejected even though you have not received your plates yet. If your registration was not under processing, then there is a chance that DMV will reject your HOV sticker application, given they don't have your VIN in their database as registered or undergoing registration yet.I’m confused. So did you or did you not submit the application without receiving the official plate first ? what are they processing if you have never submitted the application? I see you said you submitted your application and dropped in the mail “ the same day” After they told you they have started processing?? How can they process your application when nothing was originally submitted ?
