PER CURIAM.
Steve Dias appeals the district court's order construing his Fed. R. Civ. P. 60(b) motion for reconsideration of the district court's order denying relief on his 28 U.S.C. § 2255 (2012) motion as a successive § 2255 motion, and dismissing it on that basis. We have reviewed the record and conclude that the district court correctly determined that Dias' motion was not a "true Rule 60(b)" motion, but in substance a successive § 2255 motion. See United States v. McRae, 793 F.3d 392, 397-400 (4th Cir. 2015); see also Gonzalez v. Crosby, 545 U.S. 524, 531-32 (2005) (explaining how to differentiate a true Rule 60(b) motion from an unauthorized successive habeas corpus motion). Therefore, we conclude that Dias is not required to obtain a certificate of appealability to appeal the district court's order. See Mcrae, 793 F.3d at 400. The district court also correctly concluded that in the absence of prefiling authorization, it lacked jurisdiction to hear a successive § 2255 motion. See 28 U.S.C. § 2244(b)(3) (2012).
Accordingly, we affirm the district court's order. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid in the decisional process.
AFFIRMED.
