Number::Phone::Country - Lookup country of phone number
use Number::Phone::Country; #returns 'CA' for Canada my $iso_country_code = phone2country("1 (604) 111-1111");
use Number::Phone::Country qw(noexport uk); my $iso_country_code = Number::Phone::Country::phone2country(...);
my ($iso_country_code, $idd) = Number::Phone::Country::phone2country_and_idd(...);
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.
The following functions are available:
Returns the international dialing prefix for this country - eg, for the UK it returns 44, and for Canada it returns 1.
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_codeonly returns one code. See
idd_regexif you need to match a number against known IDD prefixes for a given 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,
01143662111is 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
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.
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).
Returns a list containing the ISO country code and IDD prefix for the given phone number. eg for +441234567890 it returns ('GB', 44).
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.
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 ...
