Short version is, I am wondering which number to report for HMDA. The one WITH the letters or WITHOUT the letters. The numerical portion is going to be the same; but the one system won't accommodate the loan number without the letter; and the other one won't accommodate the loan number WITH the letters. It's not a processing number - that's a whole different number. But the loan number on the LE, CD, note, etc. will not be the same as what it's booked as for servicing (on account of those letters).
