¶ 1. Defendant Roy Rheaume was convicted by a jury of
driving under the influence of alcohol (DUI), 23 V.S.A. § 1201; this DUI conviction was defendant’s third and accordingly classified as a felony. See 23 V.S.A § 1210(d) (person convicted of three or more DUIs shall be fined not more than $2,500 or imprisoned not more than five years, or both); 13 V.S.A § 1 (“any offense whose maximum term of imprisonment is more than two years ... is a felony”). Prior to his jury trial where he was convicted, defendant moved to suppress statements concerning his identity. These statements were made in response to questions asked by a Vermont State Trooper during processing. In an effort to suppress the statements, defendant argued that his Miranda rights were violated because he was read the Miranda warnings and subsequently invoked his right to silence prior to questioning by the processing trooper. The trial court denied defendant’s motion, finding that “there was no violation of the defendant’s Fifth Amendment rights, rights under the Vermont Constitution or the Vermont Public Defender Act by the process followed by the trooper.” At the enhancement proceeding, the prosecution used defendant’s date of birth and social security number to identify him and show that he had two prior DUI convictions. Defendant now appeals his felony conviction and the trial court’s denial of his motion to suppress the statements. We affirm.
¶ 2. On August 31, 2001, a Vermont State Trooper pulled over a speeding vehicle. After the vehicle stopped, the driver, later identified as Roy Rheaume, fled the vehicle and ran into a cornfield. The trooper gave chase, but was unable to see anything in the cornfield. Other troopers arrived on the scene and began searching for defendant. After approximately thirty minutes, defendant was found sleeping in *415 the cornfield. The troopers who apprehended defendant detected a strong odor of alcohol on defendant’s breath and saw that he had difficulty walking. Defendant was arrested for DUI.
¶ 3. Following the arrest, the troopers took defendant to the station for processing, which was videotaped by the processing trooper. Before defendant was given Miranda warnings, the processing trooper asked defendant several questions. 1 After defendant answered these questions, the trooper read defendant the Miranda warnings. In response to the warnings, defendant stated that he did not wish to speak with the trooper and that he wanted an attorney. Following this request, the processing trooper telephoned the on-call public defender. While the trooper had the attorney on the telephone, the trooper asked defendant his name and date of birth. The trooper also informed the attorney, in defendant’s presence, that if defendant submitted to a breath test he could be released, but if he refused he would be lodged. Defendant then spoke with the attorney and agreed to take the breath test. After defendant spoke with the attorney, the trooper, continuing to process defendant, asked him for his address and social security number. Defendant answered the processing questions, apparently truthfully.
¶ 4. Using defendant’s date of birth and social security number, the trooper obtained copies of defendant’s two prior DUI convictions: one in 1981 and one in 1997. Following a breath test, the trooper charged defendant with a third DUI offense — a felony.
¶ 5. After charges were filed, defendant moved through counsel to suppress the statements and the results of the breath test and to dismiss. The trial court considered the motion during defendant’s civil suspension hearing. Subsequent to the hearing, the parties agreed that the court should consider the evidence presented in support of suppression in the civil suspension hearing in deciding defendant’s motion to suppress evidence in the criminal case. The court granted defendant’s motion to suppress the breath test because of the trooper’s statement to the on-call attorney that if defendant refused the breath test he would be lodged, but denied his motion to suppress the statements concerning his identity. The court entered judgment in the *416 civil suspension case in defendant’s favor and set the criminal case for trial before a jury.
¶ 6. Pursuant to the procedures first outlined in
State v. Cameron,
¶ 7. Following this jury verdict, the court moved on to the enhancement phase. Because the State charged defendant with a third offense, it was required to prove beyond a reasonable doubt that defendant was convicted of DUI on two prior occasions. During this proceeding, the State used defendant’s name, date of birth, address, and social security number — information obtained after defendant had received Miranda warnings and invoked his right to remain silent — to establish that the Roy Rheaume convicted of DUI in 1981 and 1997, and the Roy Rheaume presently convicted, were the same person. At the conclusion of this proceeding, the jury found that the State had established the two prior DUI convictions. Defendant was sentenced to ninety days to five years.
¶ 8. Defendant argues here, as he did below, that his
Miranda
rights were violated when the processing trooper asked him his birth date and social security number after he had invoked his right to silence. Therefore, he claims the trial court erred when it denied his motion to suppress the answers to these questions. We review motions to suppress de novo.
State v. Pierce,
*417
¶ 9. We start with the routine booking question exception under federal law. Although, as noted below, there was a disagreement over the rationale for the holding, the United States Supreme Court recognized an exception to the requirements of
Miranda
in
Pennsylvania v. Muniz,
The Commonwealth argues that the seven questions asked by Officer Hosterman ... — regarding Muniz’s name, address, height, weight, eye color, date of birth, and current age — did not constitute custodial interrogation as we have defined the term in Miranda and subsequent cases. In Miranda, the Court referred to “interrogation” as actual “questioning initiated by law enforcement officers.” We have since clarified that definition, finding that the “goals of the Miranda safeguards could be effectuated if those safeguards extended not only to express questioning, but also to ‘its functional equivalent.’ ” In Rhode Island v. Innis, the Court defined the phrase “functional equivalent” of express questioning to include “any words or actions on the part of the police (other than those normally attendant to arrest and custody) that the police should know are reasonably likely to elicit an incriminating response from the suspect. The latter portion of this definition focuses primarily upon the perceptions of the suspect, rather than the intent of the police.” However, “[a]ny knowledge the police may have had concerning the unusual susceptibility of a defendant to a particular form of persuasion might be an important factor in determining” what the police reasonably should have known. Thus, custodial interrogation for purposes of Miranda includes both express questioning and words or actions that, given the officer’s knowledge of any special susceptibilities of the suspect, the officer knows or reasonably should know are likely *418 to “have ... the force of a question on the accused,” and therefore be reasonably likely to elicit an incriminating response.
We disagree with the Commonwealth’s contention that Officer Hosterman’s first seven questions regarding Muniz’s name, address, height, weight, eye color, date of birth, and current age do not qualify as custodial interrogation as we defined the term in Innis, merely because the questions were not intended to elicit information for investigatory purposes. As explained above, the Innis test focuses primarily upon “the perspective of the suspect.” We agree .with amicus United States, however, that Muniz’s answers to these first seven questions are nonetheless admissible because the questions fall within a “routine booking question” exception which exempts from Miranda’s coverage questions to secure the “‘biographical data necessary to complete booking or pretrial services.’ ” The state court found that the first seven questions were “requested for record-keeping purposes only,” and therefore the questions appear reasonably related to the police’s administrative concerns. In this context, therefore, the first seven questions asked at the booking center fall outside the protections of Miranda and the answers thereto need not be suppressed.
Id. at 600-02 (internal citations- omitted). Justice Brennan’s rationale that booking questions seek testimonial responses represents the majority decision because it is joined by Justice Marshall who nevertheless dissented on whether to create such an exception. See id. at 612 (booking questions sought testimonial responses because the answers would indicate defendant’s state of mind). Four justices concurred, in an opinion authored by Chief Justice Rehnquist, because they found that the answers to the booking questions were not testimonial. See id. at 608 (Rehnquist, C.J., concurring).
¶ 10. Although Justice Brennan’s opinion is only a plurality decision, all courts addressing routine booking questions after
Muniz
appear to have adopted it.
2
See
Thomas v. United States,
¶ 11. Defendant argues that two responses to the officer’s questions — his date of birth and his social security number — were incriminating, because they allowed the State to identify defendant as the person who had twice been convicted of DUI in the past, and therefore do not fit into the routine booking question exception announced in
Muniz.

As the State points out, the test under
Muniz
is not whether the information disclosed could lead to a conviction, but instead whether
*420
the questions “are reasonably likely to elicit an incriminating response from the suspect.”
Muniz,
¶ 12. Certainly, identification of the arrested person is central to the police processing function. The questions asked in this case were apparently routine, were asked as part of routine processing, and were similar to the questions asked in
Muniz.
Indeed, except for the unusual circumstances of this case where defendant was not seized while in his vehicle, the police would already have significant identification information from the operator’s license of the driver. See 23 V.S.A. § 1012(a), (b) (on request of officer who reasonably suspects operator is violating motor vehicle law, operator must provide name, address, operator’s license and vehicle registration). There is no indication in the record that the officer knew in advance of the inquiry that defendant had been convicted of DUI in the past. See
Hughes,
¶ 13. Defendant has cited cases in which courts found that birth date and social security information could be sought to help prove an element of a crime. See, e.g.,
City of Fargo v. Wonder,
*421 ¶ 14. This brings us to defendant’s second argument — that we should follow Justice Marshall’s dissent in Muniz and reject the routine booking question exception as a matter of Vermont constitutional law.
¶ 15. Chapter I, Article 10 of the Vermont Constitution provides in relevant part, “[t]hat in all prosecutions for criminal offenses ... a person [cannot] be compelled to give evidence against oneself.” In
State v. Brunelle,
¶ 16. Defendant contends that we should employ the framework for constitutional inquiry established in
State v. Jewett,
¶ 17. Defendant, largely relying on case law from the 1800s and early 1900s, asserts that the privilege against self-incrimination is deeply rooted in our state’s jurisprudence. See
State v. Hobbs,
Both the self-incrimination and search and seizure provisions of the Vermont Constitution contain wording substantially different from the parallel clauses in the Federal Charter. Thus, it is possible that these clauses could be construed *422 differently from somewhat similar provisions in the Federal Constitution or they may be given the same interpretation even though the language differs.
¶ 18. Despite the historical recognition of the privilege against self-incrimination and the language of Chapter I, Article 10, we have consistently held that, in its application to adults, the Article 10 privilege against self-incrimination and that contained in the Fifth Amendment are synonymous. See
State v. Ely,
¶ 19. Defendant next turns to the holdings in other states, arguing first that we should consider Massachusetts’ and New Hampshire’s Constitutions because they have similar self-incrimination provisions, see Mass. Const., Pt. 1, art. 12 (“No subject shall be held to ... accuse, or furnish evidence against himself.”); N.H. Const., Pt. I, art. 15 (a person shall not “be compelled to accuse or furnish evidence against himself’), and they have been interpreted as providing broader protections than the Fifth Amendment. Even if we were to find in the decisions from these states a reason to overturn our settled interpreta
*423
tion of Chapter I, Article 10, this reconsideration would be of little benefit to defendant in this case. Both these states recognize the routine booking exception for questions concerning identification that are asked to process a suspect. See
Commonwealth v. White,
¶ 20. Defendant urges us to rely on two decisions from other states that he argues reject the Muniz analysis and require that we suppress the answers to the booking questions in this case. Before we examine those decisions, we make two points about the context in which these decisions are raised. As noted above, this Court has explicitly held that the requirements of Miranda are independently applicable under Chapter I, Article 10 of the Vermont Constitution. We are one of only a handful of states to so hold. See B. Latzer, Toward the Decentralization of Criminal Procedure: State Constitutional Law and Selective Disincorporation, 87 J. Crim. L. & Criminology 63,109-10 (1996) (six states have held that their constitutional self-incrimination provision includes Miranda protections: Conn., Fla., Haw., Miss., Ore., and Vt.). Some other states have adopted aspects of the Miranda rule, but not all of it. See id. As a result, the vast majority of state courts have never faced the question before us, and we do not know how they would rule. Indeed, they might never reach the question because they might reject the wholesale incorporation of the Miranda rules on which defendant asks us to build.
¶21. Moreover, the vast majority of state courts have explicitly relied upon a routine booking exception, often without specifying whether the decision is based only on the Fifth Amendment. See
State v. Vandeveer,
¶ 22. Nevertheless, defendant urges us to rely upon two decisions,
State v. Ketchum,
¶ 23. The first case,
State v. Ketchum,
was decided under Article I, Section 10 of the Hawaii Constitution, the self-incrimination provision. The court decided that it would not adopt a routine booking question exception to
Miranda,
as described in
Muniz. Ketchum,
[W]e reaffirm the principle that “interrogation” consists of any express question — or, absent an express question, any words or conduct — that the officer knows or reasonably should know is likely to elicit an incriminating response____ The totality of the circumstances must be considered to determine whether “interrogation” has occurred, with a focus upon the officer’s conduct, the nature of the question (including whether the question is a “routine booking question”), and any other relevant circumstance.
*426
¶ 24. The second decision,
Allred,
is even less supportive of defendant’s position here. Although the decision suggests some disagreement with
Muniz
under the self-incrimination provision of the Florida Constitution, that disagreement did not extend to
Muniz’s
holding on the routine booking question exception. In fact, the court explicitly adopted' the exception: “We find however [sic] that routine booking questions do not require
Miranda
warnings because they are not designed to lead to an incriminating response; rather, they are designed to lead to essential biographical data.”
¶ 25. Finally, defendant contends that for public policy reasons we should not recognize an exception to Miranda for questions concerning identity that are asked only for administrative purposes. Defendant argues that such an exception “may provide an incentive for police to attempt to circumvent Miranda.” We are not convinced.
¶ 26. In the leading case of
Rhode Island v. Innis,
*427 The safeguards of Miranda attach whenever a person in custody is subjected to interrogation. Under Miranda, the term “interrogation” encompasses only “words or actions ... that the police should know are reasonably likely to elicit an incriminating response.” Although the focus of the inquiry is on the perception of the suspect, the police cannot be held accountable for the unforeseeable results of their words and actions. Thus, an incriminating statement made in the course of casual conversation is not the product of interrogation.
¶ 27. A blanket rule prohibiting all questioning is overbroad and unworkable. We have already rejected it in FitzGerald. We believe that the objective standards developed in Innis and Muniz define a line sufficiently bright for predictable application.
¶ 28. We also conclude that the policy interests weigh heavily against defendant’s position where the questions go to the identity of the person the police have arrested. As we said above, establishing the identity of the arrested person is a central concern of the booking function. Indeed, the failure to provide satisfactory proof of identity may provide grounds for arrest. See V.R.Cr.P. 3(c)(1). It may determine the ability to gain pretrial release. If a suspect refuses to identify him or herself, it is likely that the police can determine identity by nontestimonial methods.
¶ 29. We view questions related to defendant’s identity for booking as being closer to requests for consent to search we allowed despite
Miranda
objections in
State v. Crannell,
¶ 30. For the above reasons, we conclude that none of the analysis considerations outlined in Jewett lead us to the conclusion that we should reject Muniz under Chapter I, Article 10 of the Vermont Constitution and hold that Miranda was violated when the police requested and obtained from defendant identifying information during booking, despite the fact that defendant had invoked his right to remain silent.
Affirmed.
Notes
The State concedes that these questions were Miranda violative. The trial court found, however, that defendant’s responses did not elicit any incriminating information, and defendant did not appeal this finding to this Court.
Muniz
was the first time the Supreme Court addressed the routine booking question exception. Prior to
Muniz,
numerous state and federal courts had adopted this exception. See
United States v. Disla,
We note that in
Muniz
and many of the federal and state decisions adopting the routine booking exception, suspects were questioned without first being given the
Miranda
warnings. In this case, in contrast, the
Miranda
warnings were administered and then appellant was questioned. Defendant has not argued that this distinction has any effect on the applicable law. Thus, he has argued his position as if he was never provided any
Miranda
warnings prior to the officer asking him the booking questions. We agree that it makes no difference with respect to the routine booking question exception whether defendant did or did not receive the warnings prior to questioning because the identification questions fall outside the scope of
Miranda.
When presented with factually similar situations —
Miranda
warnings administered and then routine booking questions asked — other courts have also relied on
Muniz
and have drawn no distinctions regarding the administration of the warnings. See
United States v. Foster,
