- 6 - these circumstances, the date on an electronically generated FedEx label, created and applied by a FedEx employee, is conclusive proof of the date of mailing equivalent to a USPS postmark. Austin v. Commissioner, T.C. Memo. 2007-11; Notice 97- 26, 1997-1 C.B. 413, 414. We are persuaded that the electronically generated label on the FedEx envelope containing the petition was created and applied by a FedEx employee; the "Ship Date" of November 14, 2006, that appears on the label is therefore treated as the date of mailing for purposes of section 7502. Consequently, the petition is not deemed timely under that section. We next consider whether the notice of deficiency was valid. When the Secretary determines that there is a deficiency, "he is authorized to send notice of such deficiency to the taxpayer by certified mail or registered mail." Sec. 6212(a). Such notice of deficiency "shall be sufficient" if mailed to the taxpayer's last known address as specified in section 6212(b)(1). Section 6212(b)(1) does not create a mandatory address to which a notice of deficiency must be mailed; rather, it is a "safe harbor" available to the Commissioner which renders a notice of deficiency valid irrespective of actual receipt.
