When issuing a new Loan Estimate due to changed circumstance, such as rate locked, does the loan identification number need to changed from that of the previous LE?

The basic loan ID number must remain the same, for all LEs and the CloD(s). If you wish, you may append a "sequence number" to the loan ID number to identify specific documents. Reference comment 37(a)(12)-1.

Thank you John. I was thinking that we needed to "append" the Id number on each re-issued document.
