7

SYNOPSIS

9        use Regexp::Common qw /SEN/;
10
11        while (<>) {
12            /^$RE{SEN}{USA}{SSN}$/    and  print "Social Security Number\n";
13        }

DESCRIPTION

16       Please consult the manual of Regexp::Common for a general description
17       of the works of this interface.
18
19       Do not use this module directly, but load it via Regexp::Common.
20
21   $RE{SEN}{USA}{SSN}{-sep}
22       Returns a pattern that matches an American Social Security Number
23       (SSN).  SSNs consist of three groups of numbers, separated by a hyphen
24       ("-").  This pattern only checks for a valid structure, that is, it
25       validates whether a number is valid SSN, was a valid SSN, or maybe a
26       valid SSN in the future. There are almost a billion possible SSNs, and
27       about 400 million are in use, or have been in use.
28
29       If "-sep=P" is specified, the pattern P is used as the separator
30       between the groups of numbers.
31
32       Under "-keep" (see Regexp::Common):
33
34       $1  captures the entire SSN.
35
36       $2  captures the first group of digits (the area number).
37
38       $3  captures the second group of digits (the group number).
39
40       $4  captures the third group of digits (the serial number).
