C-2422 Mail or Courier Transport
Revision 24-3; Effective Sept. 1, 2024
All Programs
Double seal all FTI transported through the mail by sealing one envelope within another envelope. On the inner envelope, staff must mark Confidential to indicate that only the designated recipient is authorized to open it. Do not label the outermost envelope as FTI or provide any indication that it contains FTI. Use Form H1862 when mailing all paper documents that contain IRS data. The sender ensures the receiver acknowledges the receipt of the information.
