# Regexp::Common::SEN - phpMan

## 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 [Regexp::Common] 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 hyphen ("-").
    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 [Regexp::Common]):

    $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).
