NAME
Number::Phone::Country - Lookup country of phone number
SYNOPSIS
use Number::Phone::Country;
#returns 'CA' for Canada
my $iso_country_code = phone2country("1 (604) 111-1111");
or
use Number::Phone::Country qw(noexport uk);
my $iso_country_code = Number::Phone::Country::phone2country(...);
or
my ($iso_country_code, $idd) = Number::Phone::Country::phone2country_and_idd(...);
DESCRIPTION
This module looks up up the country based on a telephone number. It uses the
International Direct Dialing (IDD) prefix, and lookups North American numbers using the
Area Code, in accordance with the North America Numbering Plan (NANP). It can also, given
a country, tell you the country code, and the prefixes you need to dial when in that
country to call outside your local area or to call another country.
Note that by default, phone2country is exported into your namespace. This is deprecated
and may be removed in a future version. You can turn that off by passing the 'noexport'
constant when you use the module.
Also be aware that the ISO code for the United Kingdom is GB, not UK. If you would prefer
UK, pass the 'uk' constant.
I have put in number ranges for Kosovo, which does not yet have an ISO country code. I
have used XK, as that is the de facto standard as used by numerous international bodies
such as the European Commission and the IMF. I previously used KOS, as used by the UN
Development Programme. This may change again in the future.
FUNCTIONS
The following functions are available:
country_code($country)
Returns the international dialing prefix for this country - eg, for the UK it returns
44, and for Canada it returns 1.
idd_code($country)
Returns one, of possibly multiple, International Direct Dialing prefixes for the given
ISO Alpha-2 country code. Returns nothing if the country code is not recognised or
not supported.
The IDD prefix is needed to make a call from a country to another country. For
example, when calling the UK from the US, the caller must first dial the IDD prefix
011 to setup an international call, followed by the country calling code for the UK
(44), followed by the UK national number.
Many telephone systems allow the caller to dial a plus sign prefix (+) in place of the
IDD, in which case the system replaces the plus sign with the correct IDD prefix for
the caller's country.
Some countries have more than one IDD code, allowing the caller to route their calls
through specific networks. "idd_code" only returns one code. See "idd_regex" if you
need to match a number against known IDD prefixes for a given country.
idd_regex($country)
Returns a regular expression that matches against known International Direct Dialing
prefixes for the given ISO Alpha-2 country code. Returns nothing if the country code
is not recognised or not supported.
As an example, the regular expression for Australia (AU) will match a number of IDD
prefixes, including 0011, 0014, and 0015, making it possible to determine that
001516502530000 could be a US number being dialled from Australia.
Be aware that some numbers will match against IDD prefixes from multiple countries.
Other numbers will be valid national numbers for one country, and valid international
numbers when called for other countries. For example, 01143662111 is a valid national
number for Sheffield, England. It could also be a valid number in Austria:
Calling from within the UK:
Area code: 0114
Subscriber: 366 2111
National: 0114 366 2111
International: +441143662111
Calling from a country that uses the NANP (North American Numbering Plan):
IDD: 011
Country code: 43 (Austria)
Area code: 0662 (Salzburg)
Subscriber: 111
National: 0662 111
International: +43662111
ndd_code($country)
Returns the National Direct Dialing prefix for the given country. This is the prefix
used to make a call within a country from one city to another. This prefix may not be
necessary when calling another city in the same vicinity. This is followed by the
city or area code for the place you are calling. For example, in the US, the NDD
prefix is "1", so you must dial 1 before the area code to place a long distance call
within the country.
phone2country($phone)
Returns the ISO country code (or XK for Kosovo) for a phone number. eg, for
+441234567890 it returns 'GB' (or 'UK' if you've told it to).
phone2country_and_idd($phone)
Returns a list containing the ISO country code and IDD prefix for the given phone
number. eg for +441234567890 it returns ('GB', 44).

BUGS
It has not been possible to maintain complete backwards compatibility with the original
0.01 release. To fix a bug, while still retaining the ability to look up plain un-adorned
NANP numbers without the +1 prefix, all non-NANP numbers *must* have their leading + sign.
Another incompatibility - it was previously assumed that any number not assigned to some
other country was in the US. This was incorrect for (eg) 800 numbers. These are now
identified as being generic NANP numbers.
Will go out of date every time the NANP has one of its code splits/overlays. So that's
about once a month then. I'll do my best to keep it up to date.
WARNING
The Yugoslavs keep changing their minds about what country they want to be and what their
ISO 3166 code and IDD prefix should be. YU? CS? RS? ME? God knows. And then there's
Kosovo ...
