Will the world ever run out of phone numbers???

Question

Will the world ever run out of phone numbers???

Answer 1

Actually, that's been a bit of a problem in the U.S; with some people having upwards of 5 numbers ... home (sometimes more than one), office, cell, fax, computer, pager, etc. That's the reason the area codes have been changed.

Still, if you think of just 11 digits ... country code included, that's 99 billion numbers. I don't think we'll officially run out any time soon. If we do, we can add a digit and get an order of magnitude's worth of numbers to tack on.
