NAME

Regexp::Common::SEN -- provide regexes for Social-Economical Numbers.

SYNOPSIS

 use Regexp::Common qw /SEN/;

 while (<>) {
     /^$RE{SEN}{USA}{SSN}$/    and  print "Social Security Number\n";
 }

DESCRIPTION

Please consult the manual of the Regexp::Common manpage for a general description of the works of this interface.

Do not use this module directly, but load it via Regexp::Common.

`$RE{SEN}{USA}{SSN}{-sep}`

Returns a pattern that matches an American Social Security Number (SSN). SSNs consist of three groups of numbers, separated by a hypen (-). This pattern only checks for a valid structure, that is, it validates whether a number is valid SSN, was a valid SSN, or maybe a valid SSN in the future. There are almost a billion possible SSNs, and about 400 million are in use, or have been in use.

If -sep=P is specified, the pattern P is used as the separator between the groups of numbers.

Under -keep (see the Regexp::Common manpage):

$1: captures the entire SSN.
$2: captures the first group of digits (the area number).
$3: captures the second group of digits (the group number).
$4: captures the third group of digits (the serial number).
