OPINION OF THE COURT
This is an appeal by a federal prisoner, acting pro se, from an order of the district court denying the motion to correct his presentence investigation report pursuant to Fed.R.Crim.P. 32. The threshold question before us is whether appellant filed his notice of appeal within the time specified by Rule 4(b) of the Federal Rules of Appellate Procedure. If the appeal was untimely, we lack jurisdiction to consider it. For the reasons that follow, we conclude that in computing the timeliness of filings which are jurisdictional in nature, any delay by prison officials in transmitting notice of a final order or judgment to an incarcerated pro se litigant should be excluded from the computation. Because the effect of prison delay on the timeliness of this appeal is unclear on the record, we will vacate the order of denial, and remand to the district court to make the necessary factual determinations.
I.
Appellant, Faustino Grana, is an inmate at the Metropolitan Correctional Center (MCC) in New York, maintained by the U.S. Bureau of Prisons. On February 5, 1986, appellant pled guilty to one count of possession with intent to distribute approximately one and one-half pounds of cocaine, a Schedule II controlled substance. 1 On March 12, 1986, he was sentenced to five years imprisonment. Instead of filing a direct appeal, appellant began a series of collateral attacks on his sentence, starting with a motion to reduce his sentence, pursuant to Federal Rule of Criminal Procedure 35. The district court denied this motion by order entered April 10, 1986. Appellant then moved to vacate sentence pursuant to 28 U.S.C. § 2255. The district court denied that motion on October 7, 1986. 2
On October 7, 1986, approximately seven months after sentencing, appellant filed the first of several motions aimed at correcting alleged inaccuracies in his pre-sentence investigation report (PSI) pursuant to Feder *314 al Rule of Criminal Procedure 32. 3 The procedural history of the motions and the court’s corresponding orders are set out in the margin. 4 Appellant appeals the district court’s final order, entered April 18, 1988, denying his motion to hold the Bureau of Prisons in contempt.
Appellant filed a notice of appeal from this order on May 13, 1988, twenty-five days following the entry of the district court’s final order, and fifteen days out of time. Fed.R.App.Proc. 4(b). Appellant contends that MCC negligently handled his incoming mail, and as a result he did not receive the district court’s final order until May 5, 1988, after the expiration of the appeal period. He therefore contends that his appeal should be treated as filed within the jurisdictional time limits.
II.
Rule 4(b) provides that “in a criminal case the notice of appeal by a defendant shall be filed in the district court within 10 days after the entry of the judgment or order appealed from.” The timely filing of a notice of appeal is a mandatory jurisdictional prerequisite to the right to appeal.
United States v. Robinson,
Appellant acknowledges that his appeal is technically out of time, but argues that he has proffered a compelling justification for his late filing. As we have noted, he claims that the prison, through its own negligence, did not deliver the court’s final order until seven days after the expiration of the time for his appeal. Furthermore, appellant alleges that the Bureau of Prisons failed to comply with its own policy of tracking incoming legal mail by logging the date of the mail’s arrival and the date of the mail delivery to the intended recipient. 5 He argues that it would be unfair to hold him responsible for MCC’s negligence and that this court must grant him his opportunity to have his appeal heard. 6

In
Houston v. Lack,
— U.S. —,
The appellant in this case was faced with a situation too similar to be meaningfully distinguishable from Houston. Like the appellant in Houston, Mr. Grana also lost control over the timeliness of his appeal, and had no choice but to depend upon the prison authorities to deliver to him the notice of the entry of a final order in his case. In addition, appellant’s lack of freedom barred him from contacting the district court clerk’s office personally to inquire as to the status of his case. Indeed, the facts of the instant appeal, a criminal case, present an even more compelling argument for considering prison delay than the facts of Houston. Because the appeal period in criminal cases is shorter than that in civil cases, even a slight prison delay could compromise a prisoner’s right to appeal.
Fallen v. United States,
In
Smith v. Evans,
The teaching of Houston is that prison delay beyond the litigant’s control cannot fairly be used in computing time for appeal. We perceive no difference between delay in transmitting the prisoner’s papers to the court and transmitting the court’s final judgment to him so that he may prepare his appeal. In keeping with the teachings of Houston and Smith, and our desire to avoid creating technical pitfalls to hearing appeals on the merits, we hold that in computing the timeliness of pro se prisoners’ appeals, any prison delay in transmitting to the prisoner notice of the district court’s final order or judgment shall be excluded from the computation of an appellant’s time for taking an appeal.
Our holding does not disturb the basic principle that lack of notice of a final judgment does not affect the running of the time for appeal.
See Hall v. Community Mental Health Center of Beaver County,
III.
Because the record does not show the date the prison received notice of the district court’s final order or conclusively establish the date the prison transmitted the notice to appellant,
10
we will remand to the district court so that it may determine whether, consistent with this opinion, the notice of appeal was timely.
11
The prison will be the party with best and perhaps only access to the evidence needed to resolve such questions.
Houston,
Notes
. Pursuant to a plea agreement, the remaining counts were dismissed.
. Appellant’s Rule 35 motion was a general plea for mercy. His § 2255 motion raised the following allegations: (1) his privilege against self-incrimination was violated; (2) his conviction was obtained by use of evidence gained pursuant to an unlawful arrest; (3) the prosecution failed to disclose evidence favorable to the defendant; and (4) his conviction was obtained by use of evidence gained pursuant to an unconstitutional search and seizure.
.Essentially, appellant alleged that the PSI erroneously stated that he had threatened his co-defendant in order to prevent the codefendant’s testimony. Appellant claimed that despite the sentencing court’s agreement not to rely on this portion of the PSI because the court had found it to be untrustworthy the United States Bureau of Prisons repeatedly denied his application for a furlough based on the questionable statements.
.In response to appellant’s October 7 motion to correct the PSI, the district court ordered that appellant’s objections be appended to the PSI. Approximately five months later, appellant filed a second motion to correct the PSI, contending that he was never given adequate opportunity to review and challenge the report prior to sentencing. The district court denied the motion by order entered May 26, 1987. Appellant followed with another motion pursuant to Rule 32, which prompted the district court to order on November 12, 1987, that prison authorities could not rely upon any allegations contained in the PSI which had been found by the Court to be untrustworthy. The court further ordered that the Bureau reconsider appellant’s application for a furlough.
Shortly thereafter, appellant filed a motion requesting the court to hold the Bureau of Prisons in contempt for failing to comply with the court’s order of November 12, 1987. The court declined to find contempt of court, but ordered the Bureau to notify appellant of its decision on the furlough application. Appellant filed three more motions to hold the Bureau in contempt. By order entered April 18, 1988, the district court denied the motions, finding them to be moot, without merit, or calling for relief which the court had no power to grant.
. The record indicates that appellant has filed an informal administrative complaint with the prison, requesting that legal mail be processed in accordance with prison policy.
. As of May 5, 1988, the date appellant claims that he received notice of the final order, he could have filed a motion to extend the time for filing his notice of appeal pursuant to F.R.A.P. 4(b). Furthermore, had there been a showing of excusable neglect, the district court would have had the authority to consider an extension sua sponte. However, these procedural avenues for attaining appellate review are subject to district court discretion and therefore, do not compensate for the right to appeal which is lost due to prison delay.
. Rule 4(a)(1) provides that, in a civil case, the notice of appeal shall be filed with the clerk of the district court within 30 days after the date of entry of the judgment or order appealed from.
. Similarly, in
United States v. Solly,
.We note that the precipitous decline in the efficiency of the United States Postal Service in recent years,
see e.g., Hearing on Mail Delivery Problems Operations and Services and Postal Personnel and Modernization of the House Committee on Post Office and Civil Service,
100th Cong.2d Sess., No. 100-53 (June 2, 1988), has given rise to a veritable stream of cases which result in unfairness to
pro se
prisoner litigants who do not receive notice of decision in time to make timely motions. For that reason, this Court recommended in
Smith,
. As noted above, appellant states in his argument opposing dismissal of his case that the prison authorities delivered the notice of the final decision to him on May 5, 1988.
. We acknowledge that the remand will require an additional fact finding by a district judge who has already shown great diligence and care in considering appellant’s numerous petitions, and who has indeed afforded him relief more than once. However, we are concerned here with process, and we are obliged to clarify the law in the wake of Houston. Obviously we intimate no view as to whether appellant is entitled to any further relief.
. Indeed, the Code of Federal Regulations provides that prison staff
... shall mark each envelope of incoming legal mail (mail from courts or attorneys) to show the date and time of receipt, the date and time the letter is delivered to an inmate and opened in the inmate’s presence, and the name of the staff member who delivered the letter. The inmate may be asked to sign as receiving the incoming legal mail. This paragraph applies only if the sender has marked the envelope as specified in § 540.18.
28 C.F.R. § 540.19(a). We presume that most state correctional institutions have similar regulations.
