Another Connect posting about codes appearing after the SSN on checks issued to attorney’s by SSA.
SSA used to identify attorneys with “AT” after the SSN. The system could show the name of only the most recent attorney. The system was modified a year or two ago. Now all attorney payments begin with the letter S. In simplified terms SA means you were the first attorney paid on that SSN since the new system was implemented. You could be the first attorney and be SB, SC, or higher. If the first attempt to pay the attorney does not work, the authorizer can try to correct the entry (in which case you would still be SA) or can make a new entry (in which case you would be SB). The new system shows a name for each entry.
