Team numbers

Hi, forum.
I’m curious if our team numbers can be taken by another team if we don’t play for a year? I feel like it’s not possible, but I’m not completely sure.

As far as I know when a number is registered it can’t be re-used by a different organization.

What if an organization were to no longer exist. I think it might become available again.

Nope, I recall reading somewhere that it is reserved for a few years.

I believe that they leave it reserved for two years and it becomes available after that.
