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?

Because there are more phone numbers than people. With 10 digit phone numbers, that’s 10 billion phone numbers (minus reserved blocks), which is around 30 phone numbers per person.
And yes, we reuse numbers. Even if we didn’t, 10 billion numbers is enough to cover every American that has ever lived during the time period of phone numbers.
