Sure. In Delaware, C, PC, RV, etc. are not symbols. This is the same standard used when uploading Massachusetts plates, i.e. NI75, etc. C, PC, etc. are descriptors or types of tags, not symbols.
I thought about WY, too. The difference is that there is no plates without a county code there (exception: exempt; specialty plates), and this code visually looks like separate tiny symbols on the left side of a plate. Here my eyes see three equally large symbols C96
Buddy, everyone who allowed themselves to be rude sooner or later left this website, either on their own or with someone's help. I have witnessed this repeatedly since 2011
