In addition to SSNs, the same set of numbers is used for EINs (employers), ITINs (non-residents), and ATINs (adoptees in process). There may be others but those are the ones I see as a (currently idle) AARP volunteer tax preparer.
Some numbers are also reserved, such as 111-00-1111 for the spouse's unknown SSN when the filing status is Married Filing Separate. In view of the fact the SSNs assigned to people no longer living are still being used for employment and tax fraud, reusing numbers would really muddy the waters. > -----Original Message----- > From: IBM Mainframe Discussion List <[email protected]> On > Behalf Of Joe Monk > Sent: Tuesday, April 21, 2020 10:03 AM > To: [email protected] > Subject: Re: Here we go again > > 9 digits = 999,999,999.
