I believe that it's possible for the 1962 vehicles to have yellow or black (base) plates. If the vehicle was sold in 1962, the DMV would probably issue the yellow (base) 1956 series plates. If the vehicle was sold or registered in 1963 to 1969, possibly 1970, then they would be issued black (base) 1963 series plates. Regardless of the vehicle being a 1962 model. Vehicles not sold in California may have a license plate with a sequence that doesn't "match" the other vehicles of the same vintage. Early plate may have AAA 123. That is because they may have been brought in to the state and registered at a later date, with later model vehicles. It has been a rumor that the plates issued in 1963 have an apostrophe preceeding 63. The later plates issued did not have the apostrophe. This next part is on the black plates, which later changed to blue(base) plates, around 1970. As for the commercial plates, also known as truck plates, there was a change in how they were put in sequence. Earlier commercial plates started with a letter followed by five numbers, i.e. A 12 345. I believe that the letter A was the starting point or the earliest plates. Around 1967, the sequence changed on the truck plates i.e. 12 345 A. "A" being the beginning of the series. In late 1968 or early 1969, black plates no longer had the 63 stamped in the upper right hand corner, where the year registration sticker would be affixed. In late 1969 or early 1970, the last of the black plates were stamped from aluminum, no longer steel. By late 1970, the blue plates were being issued with another change in sequence. Three numbers followed by three letters i.e. 123 ABC. Again "A" being the beginning of the sequence. Around 1972, there was a change to seven spaces on the plates. Autos would have, as an example 1ABC234, commercial vehicles would have a sequence like 1A23456. First number in the sequence being the starting point. In 1972 personalized or vanity plates were first offered. In a blue based plate. AAA 001 through LZZ 999 would appear to be from 63 to late 64 autos. I have seen 65's with M's and N's. 66's with R,S,T's. 67's U and V's. 68's W and X's. 69's Y and Z's. I think most or all of the Y's and Z's don't have the 63 stamped on them. There are exceptions to this. My car didn't come with black plates, so I'm going to try and register a pair of black plates in July. If you have read this far, don't hold me to this, corrections are welcomed. I am not an expert on this subject, it is just through my observation that I have taken note of the black plates. I guess that is what happens when you are trying to get some black plates on your car. Members with CA black plates, post your first letter(s) and the year of your car so that others wanting to register their cars with black plates can find "correct" plates for their cars and make it look right.
