There might be a couple reasons of why I would want other numbers. While I do have a number outside of SW Pennsylvania, I am trying to keep things as simple for the caller as possible while still making my life a bit easier. And while some people may feel that 5 telephone numbers is too many, each number serves a purpose, and a role. Still, there maybe other reasons to have other numbers.
If I was wealthy enough to acquire my telephone numbers, I might be wealthy enough to have a multistory residence. With my ankles, and the fact my best days are behind me – I will need an elevator. I would want to grow old in my residence, and for that to happen, the elevator would be essential. In Pittsburgh, every elevator must have a call box, and a means for the elevator company to reach the elevator. With that said, I will need a dedicated telephone number for the elevator. This number will not need to be remembered, so there is no need to worry about that. However, this is a reason of why I might need another number.
In addition, I might decide I would want an international telephone number. For example, I currently have a United Kingdom (+44) number. They have a different numbering scheme than in the US. With that said, I would likely not get a same number as the ones listed here. With that said, the UK number is a secondary number that will ring the home phone.
