I've read and searched about this, but can't find an exact answer. Is it okay to post serial numbers of cars/tractors/whatever? Let's say for instance i had a website about antique cars. Could i post a list of the serial numbers versus year of manufacture? From what i've read it appears that factual data is more likely to be allowed, but i've yet to see anything definitive when it comes to this. My gut instinct is that it's okay since i've seen them listed on a bunch of different sites.
