Return receipt.
(iii) Return receipt. If a remitter includes two copies of a properly completed Form TCS indicating that a return receipt is requested, as well as a self-addressed, postage-paid envelope, the remitter will receive a date-stamped return receipt attached to the extra copy acknowledging the Copyright Office's receipt of the enclosed submission. The completed copies of Form TCS and the self-addressed, postage-paid envelope must be included in the same package as the submitted notice. A return receipt confirms the Office's receipt of the submission as of the date indicated, but does not establish eligibility for, or the date of, recordation.
