Didnt they stop using the first 3 digits to indicate the location of the person getting the SSN a while back ?
If we run out we could just start using alpha characters in with the numeric :-) How about base 64 SSN numbers ? :-) (my opinion only not my employers) -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Tony Thigpen Sent: Tuesday, April 21, 2020 2:34 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: [EXTERNAL] Re: SSN values (was Here we go again) But, remember, the first 3 positions indicate a zone, so that affects your calculation of how many are available. Back in the '80s, I worked for a banking software firm and we were notified by the feds that all software relating to SSNs needed to be 10 digits because there would be an expansion 'down the road'. We complied. Since we were using packed numbers, we changed everything to S9(11), but we only displayed 9 positions on the BMS screens since 11 positions would have confused everyone. Ok, it's been 30+ years and we have not seen it actually expand, but they did tell is... (Just like we knew in the 80's that Y2K would be upon us 'down the road'.)
