It doesn't matter whether they actually value you any more. The point is that investor relations is staffed by competent people, as opposed to customer service which is staffed by incompetent people as an intentional matter of efficient human capital allocation. So you can get much more reliable help if you can present the right class signals, and if you are at least theoretically allowed to call that line.
Companies literally keep a big list of all the people who have shares and how many, in case they want to send out a dividend or something. If they think it is important to check it is easy to do once they have a name. Realistically the cost of checking is probably higher than just dealing with the issue at hand so they won't.
Stocks are generally held in the name of the broker (“street name”), not the individual. I’m not saying they can’t check but I wouldn’t bet on them calling up Schwab to verify you really own 10 shares of UAL.

I thought companies only knew the brokerage, and it was the brokerage who could tie it back to a specific person ?
