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 KOS, as that is used by the UN Development Programme. This may change 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 the International Direct Dialing prefix for the given country. This is the prefix needed to make a call from a country to another country. This is followed by the country code for the country you are calling. For example, when calling another country from the US, you must dial 011.

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 KOS 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 ...
