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?

10 digits (7 for local numbers plus a 3 digit area code) give you a theoretical maximum distinct phone numbers of 10 billion. That’s roughly 30 times the population of the USA. Now there are unused area codes, prefixes and such, but that still leaves several billion possible phone numbers.
