I assume you are talking about a license plate with 7 characters on it, with 2 characters pointing out the county and the other 5 for the license plate number. If they had gone with the base 36 number like we have been talking about they could have had 60,466,200 people per county. That even leaves pleanty of room for taking out all the 4 letter word combinations as well as the zero/letter O problem. Unlike the geocaching, they would have had to have done it right the first time.... although they could have easily handed out license plates that fell between the decimal numbers... unless they really wanted them in order for some reason.
