OPINION

McDONALD, J.—

Plaintiff Alexandra M. Alvarez appeals a judgment entered after the trial court sustained the demurrer filed by defendant Brookstone Company, Inc. (Brookstone), to her complaint that alleged a violation of Civil Code1 section 1747.08 for requesting and recording her ZIP code as part of a credit card transaction. On appeal, Alvarez contends that because Pineda v. Williams-Sonoma Stores, Inc. (2011) 51 Cal.4th 524 [120 Cal.Rptr.3d 531, 246 P.3d 612] (Pineda) held that conduct violates section 1747.08, the judgment against her must be reversed. Brookstone concedes Pineda held the conduct violates section 1747.08, but argues Pineda's holding should not be applied retrospectively to its conduct and therefore the judgment should be affirmed. We conclude Pineda should be applied retrospectively and reverse the judgment to the extent it dismissed the section 1747.08 claim.

FACTUAL AND PROCEDURAL BACKGROUND

Because we are reviewing the trial court's order sustaining Brookstone's demurrer, we assume as true all facts alleged in Alvarez's complaint. (Pineda, supra, 51 Cal.4th at p. 528.)

On December 10, 2008, Alvarez filed a putative class action complaint, alleging that throughout the past 12 months Brookstone violated section 1747.08 when its retail store cashiers requested and recorded personal identification information in the form of ZIP Codes from her and other customers during credit card transactions.2 Her complaint also alleged Brookstone violated customers' constitutional right to privacy by requesting and recording that information and then covertly determining their home addresses.

On March 4, 2009, Alvarez filed a first amended complaint, alleging the same causes of action but adding the allegation that Brookstone also violated section 1747.08 by requesting and recording customers' e-mail addresses during credit card transactions.3

Brookstone filed a demurrer to the complaint, citing our holding in Party City Corp. v. Superior Court (2008) 169 Cal.App.4th 497 [86 Cal.Rptr.3d 721] (Party City), disapproved in Pineda, supra, 51 Cal.4th at page 534, that a ZIP Code is not "personal identification information" within the meaning of section 1747.08. Brookstone also argued Alvarez could not state a cause of action for violation of her right to privacy. It filed a motion to strike those portions of the complaint that alleged it collected and used customers' e-mail addresses on the ground Alvarez did not allege it requested her e-mail address and therefore she did not have standing to pursue relief for its collection of other customers' e-mail addresses. Alvarez opposed both the demurrer and motion to strike. In the event the trial court determined ZIP Codes were not personal identification information under section 1747.08, Alvarez requested leave from the court to file a motion to conduct precertification discovery to identify a suitable class representative who provided a personal e-mail address to Brookstone during a credit card transaction.

On or about July 27, 2009, the trial court issued its order sustaining Brookstone's demurrer to the complaint without leave to amend. Citing Party City, the court concluded ZIP Codes are not personal identification information under section 1747.08 and there was no reasonable expectation of privacy in that information. The court denied Alvarez's alternative request for leave to conduct discovery to ascertain a proposed class representative for the class of customers whose e-mail addresses were requested and recorded. Based on its ruling, the court concluded Brookstone's motion to strike was moot.

On May 11, 2010, the trial court entered judgment for Brookstone, dismissing the complaint with prejudice. Alvarez timely filed a notice of appeal challenging the judgment.4

DISCUSSION

I

Demurrer Standard of Review

"On appeal from a judgment of dismissal entered after a demurrer has been sustained, this court reviews the complaint de novo to determine whether it states a cause of action. [Citation.] We assume the truth of all material facts properly pleaded, but not contentions, deductions or conclusions of fact or law." (Folgelstrom v. Lamps Plus, Inc. (2011) 195 Cal.App.4th 986, 989 [125 Cal.Rptr.3d 260].) We construe the complaint "liberally ... with a view to substantial justice between the parties." (Code Civ. Proc., § 452.) If the complaint states a cause of action on any possible legal theory, we must reverse the trial court's order sustaining the demurrer. (Palestini v. General Dynamics Corp. (2002) 99 Cal.App.4th 80, 86 [120 Cal.Rptr.2d 741].)

Section 1747.08

(1) The Song-Beverly Credit Card Act of 1971 (Act) (§ 1747 et seq.) is "designed to promote consumer protection." (Florez v. Linens 'N Things, Inc. (2003) 108 Cal.App.4th 447, 450 [133 Cal.Rptr.2d 465].) Section 1747.08 generally prohibits businesses from requesting "personal identification information" during credit card transactions and then recording that information. (§ 1747.08, subd. (a)(2).) Section 1747.08, subdivision (b), defines "personal identification information" as "information concerning the cardholder, other than information set forth on the credit card, and including, but not limited to, the cardholder's address and telephone number." Any business or person who violates section 1747.08 "shall be subject to a civil penalty" up to $250 for the first violation and up to $1,000 for each subsequent violation. (§ 1747.08, subd. (e).)

III

Pineda's Holding

(2) On February 10, 2011, the California Supreme Court issued its opinion in Pineda, holding that "a ZIP Code constitutes `personal identification information' as that phrase is used in section 1747.08." (Pineda, supra, 51 Cal.4th at p. 527.) It concluded "requesting and recording a cardholder's ZIP Code, without more, violates the [Act]." (Id. at pp. 527-528.) Following an extensive analysis of section 1747.08's language, Pineda concluded: "[T]he only reasonable interpretation of section 1747.08 is that personal identification information includes a cardholder's ZIP Code." (Pineda, at p. 534, italics added.) Pineda expressly disapproved our contrary conclusion in Party City Corp. v. Superior Court, supra, 169 Cal.App.4th 497. (Pineda, at p. 534.)

(3) Pineda further concluded that, assuming the contrary interpretation of section 1747.08's language was also reasonable, its legislative history and purpose supported the plaintiff's interpretation of section 1747.08. (Pineda, supra, 51 Cal.4th at pp. 534-536.) The court reaffirmed its initial conclusion, stating: "[I]n light of the statutory language, as well as the legislative history and evident purpose of the statute, we hold that personal identification information, as that term is used in section 1747.08, includes a cardholder's ZIP Code." (Id. at p. 536.)

Pineda rejected the defendant's assertion that its construction of section 1747.08 violated due process. (Pineda, supra, 51 Cal.4th at p. 536.) It further rejected the defendant's assertion that its interpretation of section 1747.08 should be prospectively applied only. (Pineda, at p. 536.) Pineda applied its interpretation retrospectively and reversed the Court of Appeal's judgment affirming the trial court's judgment dismissing the plaintiff's complaint. (Id. at p. 537.)

IV

Retrospective Application of Pineda's Holding to This Case

Alvarez contends the California Supreme Court's holding in Pineda should be applied retrospectively to her case and, as a result, the judgment dismissing her complaint must be reversed. Although Brookstone concedes that Pineda disapproved Party City Corp. v. Superior Court, supra, 169 Cal.App.4th 497's contrary interpretation of section 1747.08 on which the trial court relied in sustaining its demurrer, it argues Pineda's holding should be prospectively applied only. We conclude the general rule of retrospective application of court decisions should apply to this case.

A

Brookstone argues retrospective application of Pineda's holding would violate due process of law because section 1747.08 was reasonably susceptible to other interpretations (e.g., Brookstone's proffered interpretation) before the issuance of Pineda. It further argues that section 1747.08's language did not clearly prohibit its alleged conduct and therefore it was not given fair notice or warning that section 1747.08 prohibits the requesting and recording of a customer's ZIP Code.

However, the premise of Brookstone's argument is not persuasive. Pineda expressly concluded: "[T]he only reasonable interpretation of section 1747.08 is that personal identification information includes a cardholder's ZIP Code." (Pineda, supra, 51 Cal.4th at p. 534, italics added.) Therefore, despite Brookstone's attempts to show the contrary, the California Supreme Court held that its interpretation of section 1747.08 was the only reasonable interpretation of that statute. Pineda further concluded section 1747.08 "provides constitutionally adequate notice of proscribed conduct." (51 Cal.4th at p. 536.) We reject Brookstone's due process argument that it did not have fair notice or warning of section 1747.08's prohibition against requesting and recording the ZIP Codes of customers during credit card transactions.

B

Brookstone also asserts considerations of fairness and public policy weigh against retrospective application of Pineda's holding. It argues there would be a greater burden on the courts and the administration of justice were Pineda applied retrospectively.5 It also argues Pineda's change in decisional law (e.g., disapproving Party City Corp. v. Superior Court, supra, 169 Cal.App.4th 497) was unexpected or unforeseeable in light of seemingly reasonable contrary interpretations of section 1747.08 by this and other courts in cases preceding Pineda's issuance on February 10, 2011.6

(4) We are not persuaded by Brookstone's arguments. Pineda's interpretation of section 1747.08 was foreseeable. Pineda concluded its interpretation was the only reasonable interpretation of section 1747.08.7 (Pineda, supra, 51 Cal.4th at p. 534.) To the extent Brookstone's cited "respected legal minds" may have interpreted section 1747.08 differently prior to the issuance of Pineda, that does not make those contrary interpretations reasonable. (See, e.g., Party City, supra, 169 Cal.App.4th at pp. 502, 518-520.) Pineda expressly concluded Party City's interpretation was not only incorrect, but also unreasonable.8 (Pineda, supra, 51 Cal.4th at p. 534.) If the California Supreme Court concludes an interpretation of the plain language of a statute is the only reasonable one, a party cannot persuasively assert that interpretation was unexpected or unforeseeable simply because certain attorneys, trial courts, and/or Courts of Appeal may have previously reached contrary conclusions regarding that statute. Pineda stated: "In our view, the statute provides constitutionally adequate notice of proscribed conduct, including its reference to a cardholder's address as an example of personal identification information (§ 1747.08, subd. (b)) as well as its prohibition against retailers recording any of the information contained on identification cards (id., subd. (d)).... [I]t is difficult to see how a single decision by an inferior court [(i.e., Party City)] could provide a basis to depart from the assumption of retrospective operation." (Pineda, supra, 51 Cal.4th at p. 536.) We reject Brookstone's argument that "[b]ecause reasonable minds could and did differ on whether a ZIP code was `information concerning the cardholder,' retroactive application of the Pineda interpretation of Section 1747.08 is patently unfair." Furthermore, we reject Brookstone's apparent argument that because Pineda's interpretation of section 1747.08 was based, in part, on the retailer's subsequent use of ZIP Code information outside of the credit card transaction, it did not have sufficient or fair notice of that interpretation.9 We conclude retrospective application of Pineda's holding to this case would not constitute "a manifest injustice," as asserted by Brookstone.

C

(5) Brookstone also asserts Pineda's holding should not be applied retrospectively to this case because it reasonably relied on Party City's interpretation in deciding how to conduct its credit card transactions in compliance with section 1747.08. However, Alvarez's complaint was filed on December 10, 2008, and it challenged Brookstone's conduct for the past 12-month period (i.e., Dec. 11, 2007, through Dec. 10, 2008). Party City was not issued until December 19, 2008 (nine days after Alvarez's complaint was filed). Therefore, contrary to Brookstone's apparent assertion, it could not have relied on Party City's interpretation of section 1747.08 in deciding how to conduct its credit card transactions during the period of December 11, 2007, through December 10, 2008. Like in Pineda, "while Party City, supra, 169 Cal.App.4th 497, reached a contrary conclusion [from Pineda], both defendant's conduct and the filing of plaintiff's complaint predate that decision; it therefore cannot be convincingly argued that the practice of asking customers for their ZIP Codes was adopted in reliance on Party City." (Pineda, supra, 51 Cal.4th at p. 536.) The court further stated: "[I]t is difficult to see how a single decision by an inferior court could provide a basis to depart from the assumption of retrospective operation." (Ibid.) Although Brookstone may have relied greatly on Party City in determining its litigation strategy and its conduct in defending against Alvarez's complaint (e.g., by filing a demurrer to the complaint based on Party City), that type of conduct generally is not relevant to the question of whether a party reasonably relied on established case law that is later disapproved or otherwise changed. Furthermore, we reject Brookstone's assertion that the California Supreme Court implicitly sanctioned or approved Party City's holding when it denied the plaintiff's petition for review of that decision and only later disapproved that opinion when it issued Pineda. The California Supreme Court in Pineda stated, in effect, that our decision in Party City could not "provide a basis to depart from the assumption of retrospective operation." (Ibid.) We, like the court in Pineda, conclude Brookstone "identifies no reason that would justify a departure from the usual rule of retrospective application." (Ibid.) None of the many cases cited by Brookstone persuade us to reach a contrary conclusion. We conclude Pineda's holding must be applied retrospectively to this case.

V

Alvarez's Alternative Relief

Alvarez requests that we reverse the trial court's order purportedly finding she did not have standing to represent the class of customers whose e-mail addresses were requested and recorded by Brookstone during credit card transactions. However, Alvarez does not cite, nor have we found, any express language in the challenged order (or elsewhere) showing the trial court made that finding. Alvarez has not carried her burden on appeal to provide a sufficient record on which we can review the purported error in denying her standing to represent the class of e-mail customers.

Alternatively, Alvarez requests we reverse the trial court's order denying her alternative request for leave to conduct discovery to identify a suitable representative for Brookstone customers whose e-mail addresses were requested and recorded during credit card transactions. She apparently requests that relief from us in the event we were to decide Pineda does not apply retrospectively to this case, thereby leaving only the e-mail claim but apparently without a class representative with standing.10

(6) However, because we reverse in part the trial court's order sustaining the demurrer to the complaint and the judgment entered thereon, we need not, and should not, address matters the trial court should address in the first instance on remand of this matter, including determining the scope of the putative class and the representative(s) with standing to represent the class, which issues the court apparently has not yet determined. We decline to award Alvarez the additional or alternative relief she requests on appeal. Nevertheless, to the extent the trial court finds Alvarez does not have standing or is otherwise not similarly situated to members of the putative class and cannot represent the class, the court should follow the general rule liberally allowing amendments of complaints by plaintiffs without standing to substitute in new plaintiffs with standing and, in the exercise of its reasonable discretion, grant or deny any future motion filed by Alvarez for precertification discovery of the identities of class members. (See, e.g., CashCall, Inc. v. Superior Court (2008) 159 Cal.App.4th 273, 288-291 [71 Cal.Rptr.3d 441].)

DISPOSITION

The judgment is affirmed as to the second cause of action for violation of the constitutional right to privacy. The judgment is reversed as to the first cause of action for violation of section 1747.08 and the matter is remanded for further proceedings consistent with this opinion. Alvarez shall recover her costs on appeal.
