NAME

Number::Phone::DE::Mobile - Check German Mobile Phone Numbers for validity and put them into a standard format.

SYNOPSIS

  use Number::Phone::DE::Mobile qw(checkmsisdn);

  $checkedmsisdn = Number::Phone::DE::Mobile->checkmsisdn($rawmsisdn);

DESCRIPTION

Number::Phone::DE::Mobile is a simple module to validate German Mobile Phone Numbers (MSISDNs) and return them in a single format.

regarding the fact, that mobile phone msisdns can contain 7 or 8 digits behind the area code and also regarding the various msisdn-output formats on wap gateways, sms-servers etc. i wrote a small perl-module that transforms all msisdns, no matter what input-format you use, into one, standard output format:

                        xxyyyzzzzzzzz
where:
x = country code
y = area code
z = subscriber number (either 7 or 8 digits...)

basically there are 10 types of msisdn-notations that are possible at present and that are supported by the module: 7-digit numbers:

0049___17x_____1234567_____=14 digits

34_____17x_____1234567_____=12 digits

00_____17x_____1234567_____=12 digits

0______17x_____1234567_____=11 digits

_______17x_____1234567_____=10 digits

8-digit numbers:

0049___17x_____12345678____=15 digits

34_____17x_____12345678____=13 digits

00_____17x_____12345678____=13 digits

0______17x_____12345678____=12 digits

_______17x_____12345678____=11 digits

comments: 1) the country code can be any number not starting with a zero. (this will work for nearly all countries except countries with a single digit country code.)

2) the area code can be any 3-digit number starting with ``1'' (i.e.: 179, 176, 150, 160, 168 etc...)

3) a leading ``+'' sign will be translated into two zeros ``00'' before its processed

4) special characters like ``+'',``&'',``;'',``_'',``-'',``.'' will be deleted from the msisdn before its processed

5) if the msisdn is not ok, the program returns ``invalid''.
