It is Citimortgage -  I returned the call -  the 1st return call I got a busy signal.  The 2nd return call I got an answer -  They WILL as for the last 6 (six)  digits of your ss# - which I provided.    The purpose of the call was because they did not receive my mortgage payment by the due date - the 16th.  they call on the 17th.    As it turned out -  my auto payment from my bank was due to reach them by the 15th - for some reason it was not acknowledged until the 22nd of the month - so my bank must not have sent it until the 15th and/or they took 5-7 days to acknowledge the payment was made.   Once Citimortgage processed the payment - I stopped receiving the calls as I was receiving it every day - 2 or 3 times a day until - Citimortgage processed.    Hope this helps.
