PER CURIAM:

Warren Lavell Jackson appeals the district court's dismissal of his complaint with prejudice. Although the district court noted that Jackson had failed to effect proper service on the defendants, the court dismissed the complaint with prejudice for failure to state a claim. For the reasons stated below, we vacate the dismissal with prejudice and remand for the district court to dismiss without prejudice for insufficient service of process.

I. Background

Jackson, an inmate at the Federal Correctional Complex in Coleman, Florida, filed a complaint pursuant to Bivens v. Six Unknown Named Agents of the Federal Bureau of Narcotics, 403 U.S. 388, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971) against prison officials claiming deprivation of his constitutional right of access to the courts for denying his request to be transferred temporarily to state custody for the purpose of testifying in his state habeas suit pursuant to a habeas corpus ad prosequendum writ. Jackson named Warden Yates, Yates' successor, Warden Johns, prison staff attorney Campbell, and two John Does as defendants.

Jackson petitioned the district court for permission to proceed in forma pauperis, but was denied because his prisoner account balance contained nearly $3000. The district court issued a four page order advising Jackson of his responsibility to serve Defendants properly and outlining the procedures that would be involved in the lawsuit.

Jackson mailed, by certified mail, copies of the complaint and summons to defendants Johns, Campbell, and Yates at the Coleman correctional facility where Jackson is housed and where they work. Defendants Johns and Campbell received the complaint there. Defendant Yates, who had retired, did not receive that mail and, in fact, has never been served.

Upon review of the proofs of service filed by Jackson, the court issued an order that Jackson had failed to meet the requirements for service of process and directing Jackson to Rule 4 of the Federal Rules of Civil Procedure to determine how proper service should be effectuated. The court also warned Jackson that failure to serve the defendants properly would result in a dismissal of his case.

Defendants filed a motion to dismiss asserting that Jackson had failed to state a claim upon which relief could be granted, and failed to effect sufficient service of process. The district court granted this motion concluding that Jackson had failed to allege a violation of a constitutional right.

II. Standard of Review

We review de novo a district court's interpretation of Rule 4 of the Federal Rules of Civil Procedure. Lepone-Dempsey v. Carroll County Comm'rs, 476 F.3d 1277, 1280 (11th Cir. 2007).

III. Discussion

It is undisputed that Jackson failed to serve the defendants properly. The Federal Rules of Civil Procedure establish the proper method for serving an officer of the United States sued in his individual capacity for acts occurring in connection with performance of official duties for the United States. See Rule 4(i)(2)(B). Rule 4(i)(2)(B) states that such officers must be served by delivering the complaint and summons personally to the defendants, by leaving copies with a person of suitable age residing at the defendant's abode, or by delivery to an authorized agent. See Rule 4(e). Jackson never had copies of the complaint and summons delivered to Defendants in compliance with Rule 4, nor attempted to do so, nor requested that United States Marshals be directed to do so pursuant to Rule 4(c)(2). Additionally, the United States must be served by delivering a copy of the summons and complaint to the United States Attorney for the district in which the action is brought — or a designated assistant United States Attorney — and by sending copies to the United States Attorney General in Washington, D.C. See Rule 4(i)(1). Jackson has never attempted to serve the United States.

Because Jackson failed to serve defendants properly, we find that this case should have been dismissed without prejudice. See Rule 4(m). It was, therefore, improper for the district court to have reached the merits in this case and to have issued a dismissal with prejudice. Pardazi v. Cullman Med. Center, 896 F.2d 1313, 1317 (11th Cir. 1990) ("Service of process is a jurisdictional requirement: a court lacks jurisdiction over the person of a defendant when that defendant has not been served."). Although Rule 4(m) provides for extensions of time to be granted where good cause is shown, we note that following his request for an extension of time to serve Defendants, Jackson simply repeated service by certified mail to the defendants' places of work and never attempted to serve the United States.

IV. Conclusion

For the foregoing reasons, the dismissal with prejudice is VACATED and the case is REMANDED for entry of judgment consistent with this opinion.

Affirmed.
