So the Internet has the http://www.IANA.org that doles out IP addresses
and other number spaces to the world. What's the equivalent in
telephony? Who assigns the country codes? Who in canada/us assigns the
area codes? Who then assigns the exchanges? I presume it's the carrier
that assigns the actual last 4 digits.
To be technical, IANA doesn't assign anything, they are a technical only
body that responds to formal requests from other bodies like ARIN for
north america, APNIC for Asia-Pacific, LANIC, AFNIC (I think), and RIPE
in Europe, and those bodies hand out IP Addresses and ICANN for DNS
allocations.
In a similar fashion the ITU controls top level country codes and then
countries sub-allocate from there, the +1 country code is split amongst
about 20 countries.
