Marshall D. Brooks seeks to appeal the district court’s order denying relief on his 28 U.S.C. § 2255 (2000) motion. We dismiss the appeal for lack of jurisdiction because the notice of appeal was not timely filed.

When the United States or its officer or agency is a party, the notice of appeal must be filed no more than sixty days after the entry of the district court’s final judgment or order, Fed. R.App. P. 4(a)(1)(B), unless the district court extends the appeal period under Fed. R.App. P. 4(a)(5), or reopens the appeal period under Fed. R. App. P. 4(a)(6). This appeal period is “mandatory and jurisdictional.” Browder v. Dir., Dep’t of Corr., 434 U.S. 257, 264, 98 S.Ct. 556, 54 L.Ed.2d 521 (1978) (quoting United States v. Robinson, 361 U.S. 220, 229, 80 S.Ct. 282, 4 L.Ed.2d 259 (1960)).

The district court’s order denying Brooks’ § 2255 motion was entered July 11, 2006. Brooks subsequently filed a Motion for Certificate of Appealability in the district court on June 28, 2007. * Even if *281 this motion were determined to be the functional equivalent of a notice of appeal, see Smith v. Barry, 502 U.S. 244, 248-49, 112 S.Ct. 678, 116 L.Ed.2d 678 (1992), we conclude that it would have been untimely filed. Because Brooks failed to file a timely notice of appeal or timely obtain an extension or reopening of the appeal period, we dismiss the appeal.

We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED.
