OPINION OF THE COURT

In September 2006, defendant Sean Smith was charged in a New York County indictment with one count each of criminal possession of a weapon in the second degree, criminal possession of a weapon in the third degree, unlawful possession of marijuana, and unlicensed driving. He ultimately pleaded guilty to both weapons charges and unlicensed driving in full satisfaction of the indictment. In exchange for his guilty plea, defendant was promised prison terms of five years for each felony weapon charge and 15 days for unlicensed driving, all to run concurrently, and five years of postrelease supervision. At his plea hearing, Supreme Court informed defendant that he would be required to register as a gun offender pursuant to New York City’s Gun Offender Registration Act (GORA).

In January 2009, defendant appeared for sentencing. When asked by the sentencing court if the People had anything to say, the prosecutor stated:

“Your Honor, the People rely on the promised sentence of five years in jail and five years [of] post-release supervision and Gun Offender Registration.

*672“And. I have provided . . . [the GORA] registration [form] to defense counsel.”

Defense counsel requested that defendant receive credit for time served, but did not otherwise object to the sentence as stated by the prosecutor. When the court pronounced defendant’s sentence, it stated that he was subject to GORA and advised him of his obligations thereunder. At no time during the sentencing hearing did defendant challenge the legality of GORA or its application to him.

Defendant appealed from the judgment of conviction and sentence, arguing for the first time that GORA was preempted by state law. The Appellate Division, First Department, unanimously affirmed, concluding that “the registration and other requirements of GORA are not part of the sentence, or otherwise part of the judgment. Instead, they are analogous to the requirements of the Sex Offender Registration Act (SORA), and a SORA determination . . . may not be reviewed on an appeal from a criminal judgment” (People v Smith, 69 AD3d 450, 450-451 [1st Dept 2010]). Thus, the Court stated, it was affirming the judgment of conviction and sentence “on the ground that no reviewable issue ha[d] been raised” (id. at 451).

A Judge of this Court granted defendant leave to appeal, and we now affirm.

Based on the New York City Council’s finding that gun offenders pose “unique dangers” to the citizens of New York City, the City Council, effective March 24, 2007, adopted GORA, a regulatory scheme to monitor gun offenders residing within the city (see Council of City of NY Intro No. 362, Comm on Pub Safety, Rep of Governmental Affairs Div, Background [June 27, 2006]; Local Law No. 29 [2006] of City of NY). GORA states that a person convicted of specified gun offenses in a court in New York City is a “gun offender” subject to registration with the New York Police Department (NYPD) (see Administrative Code of City of NY § 10-602 [d], [e]). Among other things, GORA requires that a gun offender register at the time sentence is imposed (see id. § 10-603 [a]) and personally appear at the NYPD Gun Offender Monitoring Unit within 48 hours of the date of conviction or the date of release from prison, whichever is later (see id. § 10-603 [d]). Failure to comply with GORA requirements is a misdemeanor punishable by a fine up to $1,000 and/or up to one year of imprisonment (see id. § 10-608).

The threshold question on this appeal is whether GORA registration is subject to appellate review pursuant to CPL *673450.10. “Appealability of determinations adverse to a defendant cannot be presumed because ‘a defendant’s right to appeal within the criminal procedure universe is purely statutory’ ” (People v Nieves, 2 NY3d 310, 314 [2004]). As relevant here, Criminal Procedure Law § 450.10 “authorizes a defendant to appeal from a judgment in a criminal case, which brings up for review many of the orders and rulings that precede or are part of it” (Nieves at 314). A judgment is “comprised of a conviction and the sentence imposed thereon and is completed by imposition and entry of the sentence” (CPL 1.20 [15]).

In People v Stevens (91 NY2d 270 [1998]) and People v Kearns (95 NY2d 816 [2000]), we held that the registration and notification requirements of SORA—regardless whether the specific risk level determination was made at the time of sentencing or post-judgment—are not a “traditional, technical or integral part of a sentence” that becomes incorporated within the judgment of conviction (Stevens, 91 NY2d at 276; Kearns, 95 NY2d at 818).1 Accordingly, SORA registration and notification requirements are not reviewable on direct appeal from a judgment of conviction and are not individually appealable within the criminal proceeding (Kearns, 95 NY2d at 818).

We agree with the Appellate Division that GORA’s registration and notice requirements, like SORA’s, are not a “traditional, technical or integral” part of defendant’s sentence or subsumed within the judgment of conviction. Notably, neither the Penal Law nor the Criminal Procedure Law directs or authorizes a sentencing court to impose GORA registration as part of a defendant’s sentence. If the sentencing court here had omitted advising defendant of his obligation to register as a gun offender, defendant would have nonetheless remained obligated to register under the terms of GORA (see Administrative Code of City of NY § 10-603 [a] [“A gun offender shall register with the department at the time sentence is imposed”]). In other words, pursuant to the terms of GORA, the registration of a gun offender is an administrative matter between the City of New York, the NYPD, and the offender, not a component of a gun offender’s sentence to be imposed by the sentencing court.

*674Defendant’s reliance on Nieves (2 NY3d 310 [2004]) and People v Hernandez (93 NY2d 261 [1999]) is misplaced. In both cases, we concluded that the matter sought to be appealed—initial certification as a sex offender by the trial court upon conviction and orders of protection issued during a sentencing proceeding—were part of the judgment of conviction and therefore appealable (Nieves, 2 NY3d at 312; Hernandez, 93 NY2d at 267-268). Significantly, in both cases, the challenged issues were “actually and temporally” part of the judgment of conviction (Hernandez, 93 NY2d at 270; see also Nieves, 2 NY3d at 315 [“CPL 530.13 (4) authorizes a court to issue permanent orders of protection for the benefit of victims and witnesses ‘(u)pon conviction of any offense.’ By using this language, the Legislature signaled that orders of protection issued at sentencing are part of the final adjudication of the criminal action involving defendant”]). Moreover, certification as a sex offender upon conviction and orders of protection issued at the time of sentencing are made part of the order of commitment, which is incorporated into the certificate of conviction (see e.g. Kearns, 95 NY2d at 818). Notably, the GORA registration and notice requirements do not appear on defendant’s “Uniform Sentence and Commitment” form, further supporting our conclusion that such requirements are not part of a defendant’s sentence.

In short, like SORA registration and notice requirements,2 GORA registration and accompanying notice requirements cannot be deemed a technical or integral part of a defendant’s sentence nor be incorporated into the judgment of conviction. Accordingly, GORA registration is not reviewable on direct appeal from a judgment in a criminal proceeding.

Defendant further argues that GORA is preempted by Executive Law § 259-a. Because we conclude, as did the Appellate Division, that the imposition of GORA registration is not reviewable on direct appeal, we need not reach that argument. We observe, however, that there are appropriate means by which GORA could be challenged as preempted by state law, including a CPLR article 78 proceeding or a declaratory judgment action.

*675Accordingly, the order of the Appellate Division should be affirmed.

Chief Judge Lippman and Judges Graffeo, Read, Smith, Pigott and Jones concur.

Order affirmed.
