PER CURIAM

Michael Derrick Gibson seeks to appeal his conviction.and sentence for possession of a firearm in furtherance of a drug-trafficking crime, in violation of 18 U.S.C. § 924(c)(1)(A) (2012). Appellate counsel has filed a brief pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), stating that there are no meritorious grounds for appeal but questioning whether the district court adequately complied with Fed. R. Crim. P. 11 and whether Gibson’s sentence is procedurally and substantively reasonable. The Government has moved to dismiss the appeal as untimely.

In criminal cases, the defendant must file the notice of appeal within 14 days after the entry of judgment. Fed. R. App. P. 4(b)(1)(A). With or without a motion, upon a showing of excusable neglect or good cause, the district court may grant an extension of up to 30 days to file a notice of appeal. Fed. R. App. P. 4(b)(4); United States v. Reyes, 759 F.2d 351, 353 (4th Cir. 1985).

The district court entered judgment on March 16, 2017. The notice of appeal was filed on June 8, 2017. Because Gibson failed to file a timely notice of appeal, we grant the Government’s motion to dismiss the appeal. See United States v. Oliver, 878 F.3d 120, 123 (4th Cir. 2017). This court requires that counsel inform Gibson, in writing, of the right to petition the Supreme Court of the United .States for further review. If Gibson requests that a petition be filed, but counsel believes that such a petition would be frivolous, then counsel may move in this court for leave to withdraw from representation. Counsel’s motion must state that a copy thereof was served on Gibson.

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 the decisional process.

DISMISSED 
      
      . Having reviewed Gibson’s pro se notice of appeal and his counsel’s brief, we conclude that Gibson intends to appeal from the criminal judgment entered in No. 6:15-cr-00526-TMC. Even assuming that Gibson also intends to appeal from the revocation judgment entered in No. 6:10-cr-00419-TMC-3, we construe the Government’s motion to dismiss as seeking dismissal of Gibson’s appeal from the revocation judgment and grant the Govemment’s motion because Gibson’s appeal from the revocation judgment is untimely.
     
      
      . The notice of appeal is undated. For the purpose of this appeal, we assume that the postmark date appearing on the envelope containing the notice of appeal is the earliest date it could have been properly delivered to prison officials for mailing to the court. Fed. R. App. P. 4(c); Houston v. Lack, 487 U.S. 266, 108 S.Ct. 2379, 101 L.Ed.2d 245 (1988).
