Inside %SSN%

The %SSN% variable wraps up a large expression that: identifies US Social Security Numbers; eliminates common false positives; validates the number using the highgroup.txt file; and removes all white spaces. The expression returns the number in a %SSN% variable that can be used in smart tags and user notification messages.

%SSN% expands to:

{%mark% 
%digits% %return% %mark% %<<% {{@|%digits%|\\|{%joined%%word%}}%false%}
[?] %return% %mark% %>>%
%#{\d[9]}|{\d[3]{-| }\d[2]{-| }\d[4]}%
{{@|%digits%|\\|{%joined%%word%}}%false%}[?]
%return% %mark% %<<% {{-|tel|tele|telephone|+|fax}%false%}[?]
%return% %>>%
%<SSN validate="SSN" transform="onlydigits">%
 {%digits%{-[?]%digits%}[2]}|%#\d[9]% 
%</SSN>%
