SSN's are not recycled.

>From the SSA OIG's testimony on SSN use and misuse before congress -

                                                                            
 "The SSN is a unique identifier"                                           
                                                                            
 http://www.ssa.gov/oig/Testimony05222001.htm                               
                                                                            
 SSN is a perfectly good PK for personnel systems.  If you find duplicates  
 your employer certainly needs to know about it.                            
                                                                            
 I once had a personnel database with 25 years of personnel data (about     
 1,200,000 individuals).  When we loaded it into Oracle with the SSN as PK, 
 there was one duplicate SSN.  Of course, that employer was very            
 conscientious about requiring a valid SSN.
