why do peeple use hashtags to show that they mean a phone number?

The others are absolutely right. It's unfortunate that tv and social media are dumbing people down to the point where they're unaware of things that are totally common knowledge to most people. It is also located on your telephone and referred to as a pound sign. Like when you call a toll free number and the recording asks you to press the pound sign after you make your entry. I'm not saying you're dumb, I'm just making a point that tv and social media have given no incentive for younger people to learn.
