NAME

Business::PLZ - Validate German postal codes and map them to states

VERSION

version 0.11

SYNOPSIS

    use Business::PLZ;

    my $plz = Business::PLZ->new('12345'); # croaks on invalid code

    print "$plz";     # stringify

    $plz->state;      # state or undef if not exist 
    $plz->iso_state;  # state as full ISO code

DESCRIPTION

This module validates German postal codes and maps them to states.

METHODS

state

Returns the state ("Bundesland") of a postal code as ISO 3166-2 subdivision code. The country prefix 'DE-' (or 'AT-') is not included. Some postal codes belong to more than one state - in this case only one state is returned. A future version of this module may also return multiple states.

If no state was found (so the postal code likely does not exists), this method returns undef. The method 'exists' is based on this lookup.

To get more information about a state, you can use Locale::SubCountry:

   $state_code = $plz->state;
   $state_name = Locale::SubCountry->new('DE')->full_name( $state_code );

iso_state

Returns the state of a postal code as ISO 3166-2 subdivision code, including country prefix.

exists

Returns whether the postal code is assigned. This is exactely the case if it can be mapped to a state.

SEE ALSO

There are some country-specific modules to handle postal codes, for instance PT::PostalCode and Business::DK::PO. Geo::PostalAddress contains regular expressions for postal codes of almost every country.
