The enclosure notation goes near the bottom of the letter, three lines below your signature or one line below the typist's initials, in the case of a regular business letter. Out of the seven basic parts of a business letter, the enclosure notation is the last.
How do you label enclosures in a letter?
Find your name at the end of your cover letter and double space after that. Type the word “Enclosure:” for one document, “Enclosures:” for two or more. It's also ok to use the cover letter enclosure notation “Encl.:”. Skip a line and then begin to list each of your enclosures.
Where does enclosure and CC go on a letter?
With a formal typed letter, this is possible by including a carbon copy notation at the end of your message. After your enclosure section, type the notation CC followed by a colon. Next, include the name of the person you're sending the letter to. For multiple senders, include each name on a separate line.
