Refile DLN

Refile DLN

DLN assigned to a return or other document after an audit of Campus adjustment has been completed. The tax return and related documents are filed under this refile DLN rather than the original DLN. Refile DLNs can be identified by the 4th and 5th digits of the DLN. A 47 document code means Examination has handled the return. A 54 document code means the Campus has processed the case.
