Zeb Eron Binnarr (“Petitioner”) was convicted by a jury for failing to timely register as a sex offender pursuant to section 23-3-4601 of the South Carolina Code. Petitioner appealed his conviction primarily on the ground that he did not receive actual notice of a change in the law regarding sex offender registration requirements. The Court of Appeals affirmed Petitioner’s conviction. State v. Binnar, Op. No.2010-UP-077 (S.C. Ct.App. filed Feb. 2, 2010). This Court granted Petitioner’s request for a writ of certiorari to review the decision of the Court of Appeals. We reverse.
I. Factual/Procedural History
In 2002, Petitioner was convicted of criminal sexual conduct in the third degree. As a result of this conviction, Petitioner was required to register annually as a sex offender by the Sex Offender Registry Act.2 In February 2006, Petitioner registered with the Charleston County Sheriffs Office and, in turn, *159was given a form to sign stating he understood that he was required to register again the following year in February 2007.
On July 1, 2006, section 23-3-460 was amended to require sex offenders to register biannually.3 Due to this amendment, Petitioner was required to register again in August 2006, which was six months after his birth month. When Petitioner failed to register in August 2006, he was arrested in March 2007 and indicted pursuant to section 23-3-470.4
During Petitioner’s jury trial, the State called Detective Denise Catlett of the Charleston County Sheriffs Office, who testified that she managed the county’s sex offender registry. Catlett testified she was responsible for notifying sex offenders of the change in the law in 2006. According to Catlett, the change in the law was “all over the news” and “in the newspaper” for months preceding and after July 2006. Catlett testified she took additional steps to notify sex offenders of the change in the law by mailing letters to sex offenders at their address on file, which sex offenders were required to keep current,5 informing them of the new law and the requirement to re-register.
Catlett stated that, after the law changed and sex offenders failed to appear for the biannual registration, a certified letter was sent to the address on file for the sex offender. Catlett testified that Petitioner was mailed a letter to his address on file regarding the new registration requirements.6 This letter, *160which was mailed via regular mail, was not returned. When Petitioner failed to appear to re-register, the sheriffs office mailed a certified letter to him. Catlett confirmed that this letter was never picked up and was returned to the Charleston County Sheriffs Office after three attempted deliveries by the Postal Service. Catlett admitted that Petitioner may not have received either letter prior to his required registration date in August 2006. She stated, however, that she waited until January 14, 2007 to sign an arrest warrant for Petitioner.
At the conclusion of the State’s case, Petitioner’s counsel moved for a directed verdict. In his argument, counsel cited Lambert v. People of the State of California, 355 U.S. 225, 78 S.Ct. 240, 2 L.Ed.2d 228 (1957),7 for the proposition that Petitioner was entitled to actual notice of the change in the law in order to comply with Petitioner’s due process rights. Although the indictment for the offense alleged notice was given prior to Petitioner’s registration date,8 counsel claimed the State had failed to present evidence that it provided Petitioner with actual notice of the change in the law.
In response, the State asserted it was Petitioner’s responsibility to maintain a current address with the Charleston County Sheriffs Office. Based on the language of the statute, the State claimed “[t]here was no duty for notification” and that the letters were mailed as a “courtesy.” The State contended it satisfied any burden of notification by mailing a letter to Petitioner’s last known address and noted that this letter was not returned to the sheriffs office.
*161The trial judge denied Petitioner’s motion for a directed verdict. Although the judge recognized that the statute did not “mention the notification requirement,” he rejected any contention that it was a “law of strict liability.” Despite the absence of statutory language, the judge found the “Sheriffs Department undertook to give some notice.” Because there was circumstantial evidence the sheriffs office provided notice to Petitioner of the registration requirement, the judge ruled that whether Petitioner had notice of the change in the law was an issue for the jury.
Following the judge’s ruling, defense counsel called Petitioner as a witness. Petitioner testified he did not receive any notice of the change in the law that required him to re-register in August 2006 rather than February 2007. Petitioner also denied receiving any of the letters sent by Catlett; however, he confirmed he lived at the address on file with the Charleston County Sheriffs Office and that he was living at that address in 2006.
After closing arguments, the judge charged the jury, in part, by explaining the text of section 28-8-460 and the 2006 amendment to that statute. In outlining the elements of the offense, the judge relied on language in Lambert, stating:
The question is whether or not [Petitioner] had actual knowledge or should have had knowledge of the requirement to register in this particular case, because you must find beyond a reasonable doubt that the State has proven that [Petitioner] had actual knowledge of the duty to register or that the State has proven beyond a reasonable doubt that [Petitioner] had the probability of such knowledge. If the State fails to convince you beyond a reasonable doubt that he knew of his duty to register bi-annually or that they failed to convince you of the probability of that knowledge, then it has failed to meet its burden of proof in this case because the law requires either actual knowledge of the duty to register or proof of the probability of such knowledge and the subsequent failure to comply in order to meet the burden of proof which is upon the State. (Emphasis added.)
The judge further explained that in order to “constitute a crime an act has to be accompanied by some criminal intent *162... [a]nd in this particular case ... knowledge is the element that is required, either actual knowledge or the probability of such knowledge.”
Ultimately, the jury convicted Petitioner of the charged offense and the trial judge sentenced Petitioner to the statutorily-mandated term of ninety days in jail.9
Petitioner appealed his conviction to the Court of Appeals. On appeal, Petitioner asserted the trial judge erred in: (1) finding, as a matter of law, that section 23-1M60 did not contain a notice requirement as the lack of a notice requirement violated Petitioner’s procedural due process rights; (2) failing to apply the notice requirements contained in section 23-3-440 10 to section 23-3-460; and (3) denying the motion for directed verdict given there was no evidence presented that Petitioner received notification of the new registration requirement.
The Court of Appeals affirmed Petitioner’s conviction. State v. Binnarr, Op. No.2010-UP-077 (S.C. Ct.App. filed Feb. 2, 2010). In so ruling, the court specifically found the Legislature did not include language in section 23-3-460 requiring the State to notify sex offenders about the change in the registration requirements when it amended the statute in 2006. The court declined to apply the notification requirement of section 23-3^40 into section 23-3^60, finding a clear reading of that statute “reveals the statute only requires the State to give notice of the registration requirement to a sex offender within one day of the sex offender’s release from prison.” Id., slip op. at 1.
Additionally, the court found section 23-3^160 did not violate Petitioner’s procedural due process rights. Citing State *163v. Edwards, 302 S.C. 492, 397 S.E.2d 88 (1990),11 the court noted the new, biannual registration requirement became effective one month before Petitioner was required to register with the sheriffs office. Thus, the court concluded that Petitioner had “fair notice that the failure to register on a biannual basis could result in a crime.” Id., slip op. at 2. The court further found the sheriffs office provided fair notice to Petitioner of the new registration requirements when it mailed a blanket notice and a certified letter to Petitioner’s residence. Id.
Following the denial of his Petitions for Rehearing and Rehearing, Petitioner sought a writ of certiorari for this Court to review the decision of the Court of Appeals. This Court granted the petition.
II. Discussion
Petitioner asserts the Court of Appeals erred in holding that he was not entitled to actual notice of a change in the law regarding his registration as a sex offender. Petitioner claims the notice requirement is central to the Sex Offender Registry-statutes and, thus, the failure to provide him with actual notice of the 2006 amendment to section 23-3-460 violated his rights to due process and equal protection.
In support of this contention, Petitioner notes that in February 2006 the Charleston County Sheriffs Office gave him “written, hand delivered notice that his next registration would occur in February 2007.” Because the sheriffs office provided him with these explicit instructions, Petitioner claims he did not have “fair notice” of the new registration date as he was misled regarding the correct date. In order to comply *164with this principle of “fair notice,” Petitioner asserts that more was required than a simple recognition of the fact that the new law went into effect one month before he was required to register. At oral argument, Petitioner claimed he was entitled to in-person, written notification.
Recently, we addressed this precise question in State v. Latimore, 397 S.C. 9, 723 S.E.2d 589 (2012) (Shearouse Adv. Sh. No. 10 at 17). In Latimore, we held that “to satisfy due process a convicted sex offender must have actual notice of the 2006 change to section 23-3-460, which imposed an additional registration requirement, to be convicted of violating section 23-3-470 of the South Carolina Code.” Id., at 13, 723 S.E.2d at 591. Thus, based on Latimore, we agree with Petitioner that the Court of Appeals erred in declining to recognize that a defendant must have actual notice of the reporting requirements before he can be convicted of violating section 23-3-470. We find this error in conjunction with the lack of direct or substantial circumstantial evidence that Petitioner had actual notice of the change in the law warrants the reversal of Petitioner’s conviction.
In denying Petitioner’s motion for a directed verdict, the judge specifically rejected any contention that the statute was a “strict liability law.” As evidenced by his comments, it is clear the judge agreed with Petitioner’s claim regarding his entitlement to actual notice of his duty to re-register. Although the judge’s ruling was based on a correct interpretation of the law, i.e. that actual notice was required, our analysis is not concluded as the question becomes whether the State presented sufficient evidence to withstand Petitioner’s motion for a directed verdict.
“A defendant is entitled to a directed verdict when the state fails to produce evidence of the offense charged.” State v. Weston, 367 S.C. 279, 292, 625 S.E.2d 641, 648 (2006). “When reviewing a denial of a directed verdict, this Court views the evidence and all reasonable inferences in the light most favorable to the state.” Id. “If there is any direct evidence or any substantial circumstantial evidence reasonably tending to prove the guilt of the accused, the Court must find the case was properly submitted to the jury.” Id. at 292-93, 625 S.E.2d at 648.
*165Vital to our assessment of the sufficiency of the evidence are the provisions of our state and federal Due Process Clauses, which provide that no person shall be deprived of life, liberty, or property without due process of law. U.S. Const, amend. XIV, § 1; S.C. Const, art. I, § 3. “The fundamental requirements of due process include notice, an opportunity to be heard in a meaningful way, and judicial review.” Kurschner v. City of Camden Planning Comm’n, 376 S.C. 165, 171, 656 S.E.2d 346, 350 (2008).
“[D]ue process is flexible and calls for such procedural protections as the particular situation demands.” S.C. Dep’t of Soc. Servs. v. Wilson, 352 S.C. 445, 452, 574 S.E.2d 730, 733 (2002) (quoting Morrissey v. Brewer, 408 U.S. 471, 481, 92 S.Ct. 2593, 33 L.Ed.2d 484 (1972)). The requirements in a particular case depend on the importance of the interest involved and the circumstances under which the deprivation may occur. S.C. Dep’t of Soc. Servs. v. Beeks, 325 S.C. 243, 246, 481 S.E.2d 703, 705 (1997). Accordingly, a claim of denial of due process must be analyzed with a two-part inquiry: (1) whether the interest involved can be defined as “liberty” or “property” within the meaning of the Due Process Clause; and, if so (2) what process is due in the circumstances. Bd. of Regents of State Colls. v. Roth, 408 U.S. 564, 571-73, 92 S.Ct. 2701, 33 L.Ed.2d 548 (1972).
Here, Petitioner was subject to a ninety-day mandatory term of imprisonment for failing to register. Without question, imprisonment is recognized as one of the greatest deprivations of liberty. As our United States Supreme Court has explained:
Freedom from bodily restraint has always been at the core of the liberty protected by the Due Process Clause from arbitrary governmental action. Youngberg v. Romeo, 457 U.S. 307, 316, 102 S.Ct. 2452, 2458, 73 L.Ed.2d 28 (1982). “It is clear that commitment for any purpose constitutes a significant deprivation of liberty that requires due process protection.” Jones [v. U.S.], supra, 463 U.S. [354] at 361, 103 S.Ct. [3043] at 3048 [77 L.Ed.2d 694 (1983) ] (internal quotation marks omitted). We have always been careful not to “minimize the importance and fundamental nature” of the individual’s right to liberty. [U.S. v.] Salerno, supra, 481 *166U.S. [739] at 750, 107 S.Ct. [2095] at 2103 [95 L.Ed.2d 697 (1987) ].
Foucha v. Louisiana, 504 U.S. 71, 80, 112 S.Ct. 1780, 118 L.Ed.2d 437 (1992).
With these principles in mind, we find the State failed to produce any direct or substantial circumstantial evidence from which a jury could determine that Petitioner received actual notice of his duty to re-register. Because Petitioner denied receiving any letters from the Charleston County Sheriffs Office regarding the biannual re-registration requirement, there is no direct evidence of actual notice.
In terms of circumstantial evidence, the State presented Detective Denise Catlett as its only witness who testified that she “generally” sent letters via first-class mail to the more than 800 registered sex offenders in Charleston County, and that the letter addressed to Petitioner was not returned as undeliverable. She further testified the certified letter mailed to Petitioner regarding his failure to appear to re-register was returned to the Charleston County Sheriffs Office as unclaimed. Significantly, Catlett acknowledged that Petitioner may not have received either letter prior to his required registration date in August 2006.
We also note the State failed to produce a copy of the actual letter but, instead, simply relied on Catlett’s testimony that she, as a matter of practice, mailed these form letters out on the tenth of the month preceding the re-registration deadline. Without a copy of the letter, there was no evidence that the letter had been properly printed, addressed, and mailed to Petitioner. See 58 Am.Jur.2d Notice § 43 (2002) (“It is not sufficient to assert that the general custom of one’s office is to mail all letters. Proof of actual mailing or of an office practice and procedure followed in the regular course of business, which shows that the notice has been duly addressed and mailed, is required, even in the absence of a denial of receipt.”).
Thus, we cannot conclude that an unreturned letter, without more, constitutes substantial circumstantial evidence that Petitioner received actual notice of his duty to re-register prior to the original February 2007 deadline. Cf. Jones v. Flowers, 547 U.S. 220, 234, 126 S.Ct. 1708, 164 L.Ed.2d 415 (2006) *167(holding that taxpayer was not provided sufficient notice of a tax sale involving his property where unclaimed letters “suggested] that [the taxpayer] had not received notice that he was about to lose his property,” and concluding that the “State should have taken additional reasonable steps to notify [the taxpayer], if practicable to do so”).
In reaching this conclusion, we express our concern regarding the implementation of the biannual re-registration requirement. Because the change in the law imposed an additional registration requirement for sex offender registrants, who were formerly required to register annually, we believe the Sheriffs Office needed to do more than passively rely on an unreturned letter to ensure compliance with the change in the law. In this limited set of circumstances, we find the Sheriffs Office could have made a phone call or sent a deputy to Petitioner’s house as his contact information had not changed between August 2006, the new deadline, and February 2007, the original deadline.
Given the significant deprivation of liberty for one who is convicted of failing to re-register due to a change in the law, we hold that substantial circumstantial evidence of actual notice is not satisfied by a negative inference arising from unreturned first class mail. To hold otherwise would effectively minimize a person’s significant liberty interest as we have recognized the need for strict compliance to notice requirements even in cases where a property interest was at stake. Cf. Hawkins v. Bruno Yacht Sales, Inc., 353 S.C. 31, 39, 577 S.E.2d 202, 207 (2003) (recognizing that section 12-51-40 of the South Carolina Code, which controls the procedure for notifying delinquent taxpayers that property will be sold to collect delinquent taxes, required that “levy notices on personal property must be sent via certified mail, return receipt requested in order to accomplish ‘levy by distress’ ”).
III. Conclusion
In view of our decision in Latimore, we hold the Court of Appeals erred in declining to find that actual notice of the reregistration requirement found in section 23-3-460 was necessary to sustain a conviction under section 23-3-470. Because the State failed to provide any direct or substantial circumstantial evidence from which a jury could determine that *168Petitioner had actual notice of the change in the law, we find the trial judge erred in failing to direct a verdict of acquittal. Accordingly, we reverse Petitioner’s conviction.
