This is more a shower thought that has started to eat at me. Even with the addition of area codes and country codes, with all the businesses and people with multiple phone lines, how are we not out of available phone numbers? Is this something to even be concerned about or is there a process to retire and recycle unused numbers?

What do you think the biggest number is?
Sweden for example had 5 digit numbers, in 1995 they added one more. Now they have 6 digit numbers. If they need, they can add more.
