Actually, there's no E164 number string with 0 :) Remember to always work in
that format.

You can add the numbers to carrier A, B, C via the provisioning interface. This
is not perfect though. remember that you're dealing with block and porting a
number is just porting a larger block. I've seen this being used in the
provider but never with more than 50.000 blocks in a single carrier. I don't
know what the performance would be with millions of ported block.

What we do in these cases is add a LNP (local number portability) db where
millions of numbers can be stored and the routing decisions are checked there
before using the generic ones.
