I think that "1" is the country number for the USA! (It's
certainly the country
number used for the USA in international phone calling, aren't
those numbers the
same?)
If http://userpage.chemie.fu-berlin.de/diverse/doc/ISO_3166.html is
accurate, the USA number is 840, and all the country codes are three
digits. (Other references, including at iso.org, also indicate that
the ISO 3166 numeric codes are all three digits.) A few start with
"00" but "001" isn't in the list, though "100" is Bulgaria.
As for numbers used for international dialing, I'd gotten the
(possibly mistaken?) impression somewhere that "00" and "011" are
pretty common. It would be pretty weird for every country to have a
different way of doing international dialing. (I'm sure there are
multiple, but to making an effort to make it per-country would just
be so wrong.) Also, the international-dialing codes *for* different
countries vary in length; the USA is "1", others are up to five
digits according to http://kropla.com/dialcode.htm, though some of
the longer ones appear to be subsets of others (e.g., "1" for US/
Canada/etc followed by an area code for some interesting entity that
got listed, or "881" for Global Mobile Satellite System followed by
one or two more digits for a specific system, etc).
