Hi all!
I'm looking for some piece of code or class which giving a phone number
it returns me from wich country is this phone.
Do you know where I can find something like this?
Thank you in advanced!
As a little project, I took the link provided by "the other" Rob and make
this little search tool.
It only looks at the beginning numbers. It does no number validation. I
don't validate the length of the number. ie: I would have to know the
min/max lenth of each phone number for that given country/region, and I
didn't search for that information.
You can't check for length, that depends on each national administration and
while some countries have all phone numbers exactly the same length, some
other countries do it the old style: small phone exchanges have few digits,
larger have more, which gets compensated by the smaller exchanges having
longer area codes.
The idea is that within small towns, you dial short numbers to reach your
neighbour and, if someone dials from outside the area, they have to dial a
longer area code prefix, but since the town is small, there is a lesser
chance that many people will have any business dialing them anyway so,
overall, you get to dial less. Also, in electromechanical phone exchanges,
each extra digit (actually couple of digits) requires an extra row of
'selectors', which are (were) expensive.
This still happens at the country level, not because it really matters
nowadays but due to the existing technology when it was agreed on it. Large
countries in Latin America have two digit country codes (political
maneuvering at the time of assignment distorted this somewhat, letting Peru
and Cuba get 2 digits which don't fit their actual number of phone lines).
Thus, from 51 to 58 they are assigned to the larger countries. The 59x and
50x ranges (in phone numbering the zero is after the nine within the same
decade) go to countries with less phone lines.

Let me know what you'll think.
