Opinion for the Court filed by Circuit Judge GRIFFITH.
Jerome Carter pled guilty to five counts of bank robbery and was sentenced to 150 months in prison. The length of his sentence was based, in part, on the district court’s finding that his criminal history included four theft convictions in Maryland. On appeal, Carter challenges that finding because it was based solely on state court computer records that are, he argues, insufficient to prove prior convictions. We disagree and affirm the sentence.
I.
Over the span of six weeks in June and July 2007, Carter netted more than $17,000 in a string of bank robberies across Washington, D.C. The police arrested Carter on July 29, 2007. On October 5, he pled guilty to five counts of bank robbery in violation of 18 U.S.C. § 2113(a) *658 (2006). In the Presentence Investigation Report (PSR), the United States Probation Office calculated a Sentencing Guidelines range of 120 to 150 months, based in part on Carter’s criminal history. Using the Guidelines point system, the PSR assigned Carter a criminal history score of 18. Six of his 18 points came from four Maryland theft convictions. The PSR did not report the source of its information about the Maryland convictions.
In a presentence memorandum filed with the court, Carter objected to the PSR’s calculation of his criminal history score, claiming there was insufficient evidence of the prior Maryland theft convictions. Carter argued the district court could not use a criminal history score that relied on these insufficiently substantiated prior convictions. Omitting the Maryland convictions, Carter maintained his criminal history score was only 12, which, when combined with his total offense score, corresponds to a guideline range of 110 to 137 months.
At the sentencing hearing, the government produced Maryland state court records of the disputed convictions. App. at 46-62. The records were printouts of entries from the District Court of Maryland Criminal System Inquiry Charge/Disposition Display database. The database entries for each conviction include Carter’s name, other identifying characteristics, the charge, the case number, the plea, the disposition, and the sentence. The Maryland court clerk’s office certified each printout. 1
In the face of these records, Carter continued his objection to the sufficiency of the evidence, arguing that the possibility of data-entry errors rendered the computer records inherently unreliable. He suggested the government needed to produce a copy of the “actual court jacket” for each proceeding to prove the prior convictions. Tr. 3. The district court offered to postpone the hearing to give Carter an opportunity to present contrary evidence. Carter declined. Id. at 5-6.
The district court rejected Carter’s challenge, concluding the computer records were reliable evidence of the Maryland convictions. Id. at 6. The district court adopted the PSR’s calculation of a criminal history score of 18 and its recommended guideline range of 120 to 150 months. The court then sentenced Carter to 150 months’ imprisonment. Carter appeals that sentence. We have jurisdiction under 18 U.S.C. § 3742.
II.
Carter’s appeal challenges the district court’s factual conclusion that Carter was convicted of the four Maryland theft offenses used to enhance his criminal history score. We review the district court’s factual findings at sentencing for clear error, see
In re Sealed Case,
*659
When seeking a sentence enhancement, the government must prove a prior conviction by a preponderance of the evidence.
See In re Sealed Case,
Evidence is competent to support factual findings at sentencing if it bears “sufficient indicia of reliability to support its probable accuracy.” U.S. Sentencing Guidelines Manual § 6A1.3 (2008) [hereinafter U.S.S.G.]. The certified records of a state court are presumptively reliable.
See
Fed. R.Evid. 803(8) advisory committee’s note (justifying the hearsay exception for public records on the basis of their inherent reliability). The presumed reliability of public records “is found in the declarant’s official duty and the high probability that the duty to make an accurate report has been performed.” 2 McCormick on Evidence § 295, at 328 (6th ed.2006); see
Chesapeake & Del. Canal Co. v. United States,
Carter nevertheless argues these computer records cannot be reliable because there is no assurance that they conform to the official case files or signed judgments of conviction. Appellant’s Br. at 5-7. We recognize the possibility of human error in data entry. But the mere possibility of error^ — the lynchpin of Carter’s argument — does not warrant the conclusion that these records, maintained and certified by a state court, are inherently unreliable.
See Thompson,
For the first time on appeal, Carter points to a discrepancy between the computer record corresponding to his 1998 theft conviction and the PSR’s description of the same offense. The computer record indicates a one-year sentence for this conviction, whereas the PSR lists a sentence of 60 days. Appellant’s Br. at 9. Carter alleges no other inaccuracies in the records but presents this discrepancy as demonstrative evidence of their general unreliability. We are unconvinced. This single alleged inaccuracy does not introduce clear error into the district court’s conclusion *660 that these records were reliable evidence of prior convictions. 2
Carter also attempts to discredit the certified computer records because they present certain information in a truncated format. In particular, the records do not cite the statute under which Carter was convicted. They state simply “Theft: Less $300 Value.”
See, e.g.,
App. at
57.
Carter suggests the omission of the statute of conviction renders these records inadequate for certain determinations under the Guidelines. Appellant’s Br. at 12-13. This may be true in some cases, such as when a sentencing court may need to consider the statute of conviction to determine if a prior offense is a “crime of violence” under the Guidelines.
See United, States v. Andrews,
Finally, Carter argues our decision in
United States v. Price,
Carter reads too much into Price. The Price court did not have before it any specific documentation supporting the alleged convictions. The court did not describe what information its hypothesized docket listing contained or whether the docket listing was an officially certified court record. Here, the sentencing court had before it certified records with information sufficient to identify the defendant and make the necessary criminal history calculation. It did not rely simply on an unadorned PSR reference to state court records; it had the records themselves. *661 We decline to conclude the Price court’s dictum concerning a hypothetical PSR reference to a hypothetical docket listing forecloses reliance on the certified Maryland court records proffered here.
III.
Taking another tack in his challenge to the Maryland records, Carter argues they were insufficient to prove a pri- or conviction under
Shepard v. United States,
Shepard
concerns how a sentencing court determines the “character” of an offense to which a defendant previously pled guilty.
Shepard
cannot be stretched so far. It “did not address what documents can be used to prove the
fact of a prior conviction,
but was concerned only with what documents can be used to prove the
facts underlying a conviction.” ZunigaChavez,
Carter’s attempt to find support in
Apprendi
fares no better. In
Apprendi,
the Supreme Court held that “[ojther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.”
Apprendi’s reliance on “procedural safeguards” concerns the proceeding in which a prior conviction was rendered, not the evidence used to prove the prior conviction in a subsequent sentencing. Utilizing a reliable computerized record of conviction — itself subject to adversarial testing at sentencing — to establish a prior conviction does not undermine the procedural safeguards attendant to the process by which the prior conviction was obtained. Apprendi is inapposite to the issue in this case.
IV.
Carter’s final argument challenging the length of his sentence is his claim that the district court erroneously imposed on him the burden of disproving his prior convictions. He contends that the district court’s offer to postpone his sentencing hearing so that he could seek evidence that might rebut the government’s proffer of the state court records improperly or unconstitutionally imposed on him the burden of disproving his prior convictions. Appellant’s Br. at 17-20.
Carter’s argument would only be valid if the evidence that the government introduced had been insufficient to sustain its burden of proof. In that case it would have been improper to place a burden on Carter to prove he was not convicted of the thefts. But here, the district court explained that the government’s uncontradicted and reliable evidence was sufficient to sustain its burden of proof. This placed no improper or unconstitutional burden on Carter. A defendant at sentencing may argue that the government’s evidence is
*663
insufficient without putting forward any affirmative evidence.
See Mitchell v. United States,
Y.
Because the district court did not err in concluding the certified computer records of the Maryland courts were sufficient to prove his prior convictions, we affirm Carter’s sentence.
So ordered.
Notes
. The government provided this documentation for not only the four theft convictions mentioned above, but also two other Maryland convictions against which Carter lodges the same sufficiency challenge. Because those two convictions were more than ten years old at the time of the instant offense, they did not count towards Carter's criminal history score or impact his guideline range. See U.S. Sentencing Guidelines Manual § 4A 1.2(e)(2) (2008) [hereinafter U.S.S.G.].
. Nor does this discrepancy create reversible error in the district court’s calculation of Carter’s criminal history score. Both the computer record and the PSR’s account establish that Carter was convicted of theft in 1998 and received a sentence of at least 60 days. That is sufficient to support the district court’s finding that Carter had a conviction resulting in a sentence of 60 days or more,
