If you're legally blind in the US, I believe your state is obligated to provide mobility training regardless of where you are, but don't quote me on that. I had an acquaintance who was a several hour walk from the nearest bus stop get training at home, so there's no reason you should be denied training.

Frankly, I think most people should have orientation training, because something as simple as a building getting painted over can really throw off sighted people, but I digress.

Even if you aren't totally blind, learning to properly use a cane, especially to help find things you can not or can no longer see, is a great safety tool.

I'm not quite sure why anyone would suggest an ID cane, I know what they're for, but they give the look of a cane without the added safety, which is weird to me.

Identity Canes are a thing u/laconicflow. They are used to alert others that the person has low vision and may need help crossing streets, may not see others to avoid a collision, etc. My understanding is that any VIP can use one.
As for Mobility and Orientation training, it depends on your state. I live in a tiny rural town and the O&M person came to me. We worked on my specific routes.

Many people don't need training for an ID cane, but it can be helpful. In Canada, training isn't required and people can just buy it.

If you’re in the US, your state should have a department of human services. They should have some sort of blindness department. Contact them for services, or go through the NFB, Lighthouse, AFB, etc.

An identification cane could be useful in your situation, but most states legally require that you be diagnosed as blind or visually impaired to use a cane. I would suggest mobility training before any cane use, if you are unfamiliar with using a cane. I would contact National Federation for the Blind and see if they have any advice for receiving mobility training in your rural community.

I've never heard of a caine used simply as identification. It isn't just a stick its a tool, and there's a way to use it. Your state should have some sort of "we help blind people" agency. Call them.
