SUBSTITUTE OPINION ON REHEARING
We deny the State’s Motion for Rehearing, withdraw our previous opinion of November 30, 2004, and issue this substitute opinion reversing and remanding appellant’s case. Appellant Banks was convicted of failing to register as a sex offender and received a twenty-five year prison sentence after the jury found that two enhancement paragraphs were true. Appellant contends (1) his prior conviction was improperly admitted, (2) his sentence should not have been enhanced, (3) the trial court erred in refusing his request for a limiting instruction, and (4) the evidence was legally and factually insufficient to convict him. Because we find the trial court erred in admitting appellant’s penitentiary packet to prove appellant had been convicted of an offense that required appellant to register as a sex offender, we reverse and remand on that ground. 1
Background
Appellant was convicted of failing to register as a sex offender under article *651 62.10 of the Texas Code of Criminal Procedure. This article requires a person with a reportable offense to register with the appropriate local authority if he or she has resided or intends to reside in a Texas county for more than seven days. Tex.Code Crim. Proc. art. 62.02. To support a conviction, appellant must have 1) been finally convicted of a reportable offense, 2) resided in Harris County for seven days, and 3) failed to register. Id. To prove appellant was finally convicted of a reportable offense, the State introduced an Illinois “penitentiary packet,” purportedly evidencing appellant’s final conviction for aggravated criminal sexual assault in Illinois, a reportable offense. 2 For the reasons that follow, we conclude the evidence of his prior conviction was improperly admitted. Because we sustain appellant’s first point of error and remand on that ground, we do not address appellant’s other contentions.
Analysis
A. Texas law determines whether the State offered sufficient documentary proof of a final conviction.
Appellant’s purported prior conviction is from another state, Illinois. Unless the State establishes that another state’s laws differ, we presume that state’s law is the same as Texas law regarding what constitutes sufficient documentary proof of a final conviction.
See Langston v. State,
B. In Texas, to establish a defendant’s final conviction, the State must bring forth admissible evidence that shows a final conviction exists and that the defendant is the person who was convicted.
To prove a defendant has been convicted previously, the State must come forward with two categories of proof — the first proving the conviction and the second linking the defendant to that conviction.
*652
See Beck v. State,
1.The State can use ‘penitentiary packets to show a valid final conviction.
To satisfy the first proof requirement — proof of a valid final conviction— the State regularly introduces “penitentiary packets” or “pen packets,” as the State did in appellant’s case. The Texas Court of Criminal Appeals has held that, “to be considered as evidence of a final conviction, a pen packet must contain a judgment and sentence, properly certified.”
Langston,
2.Penitentiary packets must satisfy the usual authentication requirements.
As with any other piece of documentary evidence, the State must authenticate the documents as a prerequisite to their admissibility. Tex.R. Evid. 901(a);
Cortez v. State,
3.Appellant’s penitentiary packet should not have been admitted because the State failed to prove its authenticity.
*653 Appellant’s Illinois penitentiary packet contains three single-page documents: 1) an “Order of Sentence and Commitment to Illinois Department of Corrections,” (see Exhibit A) 2) a fingerprint card, and 3) an “Illinois Department of Corrections Bureau of Identification Offender Report.” It does not contain any certification by an Illinois official, nor does it bear an Illinois seal. Because the packet lacks certification and a seal, appellant’s penitentiary packet was not self-authenticating under Texas Rule of Evidence 902. Tex.R. Evid. 902(1) (providing for self-authentication when domestic public documents are under seal); Tex.R. Evid. 902(2) (providing for self-authentication when domestic public documents are not under seal but bear an officer or employee’s signature and are accompanied by a certification under seal that the signer has official capacity and the signature is genuine); Tex.R. Evid. 902(4) (providing for self-authentication of certified copies of public records).
The only evidence of authenticity the State points to on appeal is the testimony it elicited that appellant’s fingerprints matched those found in the packet. The State’s reliance on the fingerprint match to authenticate the entire penitentiary packet is misplaced. The fingerprint match goes to the second category of proof — proving the defendant is the person previously convicted — and fails to prove that the documents in the packet are what the State asserts them to be.
See Cole v. State,
A The erroneous admission of the penitentiary packet requires reversal because it affected appellant’s substantial rights.
Because we find the packet should not have been admitted, we do not address whether the documents are the functional equivalent of a judgment and sentence, such that they prove a valid and final conviction. We do note, however, that the State has cited no case, nor have we located one, holding that a similar penitentiary packet — completely lacking a judgment and sentence
and
devoid of any indicia of authenticity — can sufficiently prove a prior conviction.
Cf., e.g., Johnson v. State,
Proof of a prior conviction for a reportable offense is an essential element of failing to register in violation of article 62.02. Tex. Code Crim. Proc. art. 62.02. As the penitentiary packet was the only evidence the State relied upon to prove appellant was previously convicted of a reportable offense, we have no doubt that its improper admission affected appellant’s substantial rights.

Notes
. The State urges in its first issue in its motion for rehearing that this court must address appellant’s legal sufficiency challenge. Ordinarily, a reviewing court must address a legal sufficiency challenge because, if sustained, the appellant receives an acquittal.
Rankin v. State,
. We initially rejected the State’s contention that appellant failed to preserve error with respect to his complaints that the penitentiary packet was not properly authenticated and failed to prove a final conviction. The record reveals appellant objected to the packet’s authenticity and further objected the packet contained no final judgment of conviction. In denying the State’s motion for rehearing, we again decline to find that
Ortiz v. State
requires an appellant to do more to preserve error with respect to the authentication of a document purportedly proving a prior conviction.
. In its third and final issue in its motion for rehearing, the State sirgues that any error did not affect appellant’s substantial rights.
See
Tex.R.App. Proc. 44.2(b). The State urges us to find that other evidence of appellant's guilt was overwhelming.

S.W.3d 352, 359-60 (Tex.Crim.App.2002) (finding relevant factors for harm analysis under Rule 44.2(b) include the character of the alleged error considered in the context of the other evidence of defendant’s guilt in the case). In support of that assertion, the State points to the following testimony. Officer Frederickson stated she discovered appellant failed to register despite a duty to do so. Sergeant Roberts stated he notified appellant of his duty to register. Detective Pratt stated that he examined the out-of-state conviction and determined appellant had a duty to register. And appellant signed a document indicating he had a duty to register. However, this testimony proves only that these individuals
believed
there was a duty to register and not that appellant had been finally and validly convicted of a reportable offense. Moreover, the State did not rely on this testimony to show appellant was convicted of a reportable offense. We do not find that the improper admission of the penitentiary packet “did not influence the jury, or had but a slight effect” when the record reveals the State, in its closing argument, relied
exclusively
upon the penitentiary packet to show appellant was previously convicted of a reportable offense and, thus, required to register.
