OPINION
Hoping to represent a nationwide class of consumers, Daniel Pilgrim and Patrick Kirlin sued two companies responsible for creating and marketing a healthcare discount program, alleging that the companies had used deceptive advertising to sell *945 their product. The consumer-protection laws of many States, not just of Ohio, govern these claims and factual variations among the claims abound, making a class action in this setting neither efficient nor workable nor above all consistent with the requirements of Rule 28 of the Federal Rules of Civil Procedure. We affirm.
I.
In 2007, Universal Health Card and Coverdell & Company created a program designed to provide healthcare discounts to consumers. Membership in the program gave consumers access to a network of healthcare providers that had agreed to lower their prices for members. Universal placed ads in newspapers around the country encouraging customers to visit its website or call its toll-free hotline to learn more about the program and to sign up for a membership. Coverdell was responsible for maintaining the network of healthcare providers and for reviewing Universal’s advertising materials.
Some people did not like the program. They discovered healthcare providers listed in the discount network that had never heard of the program, and complained that the newspaper advertisements, designed to look like news stories and dubbed “advertorials,” were deceptive.
Two disenchanted consumers, Pilgrim and Kirlin, sued Universal and Coverdell in federal court, seeking to represent a nationwide class of all people who had joined the program. The opt-out class encompassed 30,850 people. The district court exercised jurisdiction under a provision of CAFA, the Class Action Fairness Act of 2005, 28 U.S.C. § 1332(d), which grants jurisdiction over class actions in which the amount in controversy exceeds $5 million and the parties are minimally diverse. The plaintiffs complained that the defendants advertised the program as “free” when it included a nonrefundable registration fee and a monthly membership fee after the first thirty days. Even then, the program was worthless, they added, because the advertised providers in their area did not offer the featured discounts. Based on these and other allegedly deceptive practices, the plaintiffs claimed that the companies had violated the Ohio Consumer Sales Practices Act as well as Ohio’s common law prohibition against unjust enrichment.
Coverdell filed a motion to dismiss the complaint under Rule 12(b)(6), which the district court granted. It reasoned that Universal, not Coverdell, peddled and sold the memberships, making Coverdell too far removed from the transactions to qualify as a “supplier” under Ohio law or to have to answer to an unjust-enrichment claim under Ohio law.
Of more pertinence to this appeal, Universal filed a motion to strike the class allegations, which the district court also granted. It reasoned that, under Ohio’s choice-of-law rules, it would have to analyze each class member’s claim under the law of his or her home State. “Such a task,” the district court concluded, “would make this case unmanageable as a class action” and would dwarf any common issues of fact implicated by the lawsuit. Reasoning that the claims of the named plaintiffs did not exceed $75,000, the district court dismissed the lawsuit without prejudice for lack of subject matter jurisdiction.
II.
Rule 23 of the Federal Rules of Civil Procedure governs class actions in federal court. To obtain class certification, a claimant must satisfy two sets of requirements: (1) each of the four prerequisites under Rule 23(a), and (2) the prerequisites *946 of one of the three types of class actions provided for by Rule 23(b). A failure on either front dooms the class. A district court’s class-certification decision calls for an exercise of judgment; its use of the proper legal framework does not. So long as the district court applies the correct framework, we review its decision for an abuse of discretion.
In this instance, the district court opted to focus on a failure to meet the predominance requirement under Rule 23(b), more particularly under Rule 23(b)(3), the only conceivable vehicle for this claim. To demonstrate predominance, parties seeking class recognition must show that “questions of law or fact common to class members predominate over any questions affecting only individual members.” Fed.R.Civ.P. 23(b)(3). The plaintiffs could not do that here, the district court held, because each class member’s claim would be governed by the law of the State in which he made the challenged purchase, and the differences between the consumer-protection laws of the many affected States would cast a long shadow over any common issues of fact plaintiffs might establish. That judgment is sound and far from an abuse of discretion for three basic reasons.
Reason one: different laws would govern the class members’ claims. As the parties agree (quite properly, we might add), Ohio’s choice-of-law rules determine which, consumer-protection laws cover these claims. See
Muncie Power Prod., Inc. v. United Techs. Automotive, Inc.,
Gauged by these factors, the consumer-protection laws of the potential class members’ home States will govern their claims. As with any claim arising from an interstate transaction, the location-based factors point in opposite directions: injury in one State, injury-causing conduct in another; residence in one State, principal place of business in another. Yet the other factors point firmly in the direction of applying the consumer-protection laws of the States where the protected consumers lived and where the injury occurred. No doubt, States have an independent interest in preventing deceptive or fraudulent practices by companies operating within their borders. But the State with the strongest interest in regulating such conduct is the State where the consumers — the residents protected by its consumer- protection laws — are harmed by it. That is especially true when the plaintiffs complain about the conduct of companies located in separate States (Universal in Ohio; Coverdell in Georgia), diluting the interest of any one *947 State in regulating the source of the harm yet in no way minimizing the interest of each consumer’s State in regulating the harm that occurred to its residents.
To conclude otherwise would frustrate the “basic policies underlying” consumer-protection laws.
Morgan,
Working to overcome this conclusion, plaintiffs offer up a pair of Ohio common pleas court decisions that applied the Ohio Consumer Sales Practices Act to out-of-state sales by Ohio suppliers.
See Parker v. Berkley Premium Nutraceuticals, Inc.,
In the final analysis, Morgan’s choice-of-law rules make clear that the consumer-protection laws of the State where each injury took place would govern these claims. In view of this reality and in view of plaintiffs’ appropriate concession that the consumer-protection laws of the affected States vary in material ways, no common legal issues favor a class-action approach to resolving this dispute.
Reason two: any potential common issues of fact cannot overcome this problem. Even if a nationwide class covering claims governed by the laws of the various States could overcome this problem by demonstrating considerable factual overlap, a point we need not decide, this is not such a case. The defendants’ program did not
*948
operate the same way in every State and the plaintiffs suffered distinct injuries as a result. A core part of the claim is that the program was worthless because the listed healthcare providers near the plaintiffs did not offer the promised discounts or because there were no listed providers near them in the first place. But to establish the point, the plaintiffs would need to make particularized showings in different parts of the country, particularly since the program apparently satisfied some consumers, as confirmed by the unchallenged reality that fifteen percent of those who signed up remained enrolled months after the suit was filed. Where and when featured providers offered discounts is a prototypical factual issue that will vary from place to place and from region to region.
Cf. Wal-Mart Stores, Inc. v. Dukes,
564 U.S. -,
On top of that, the advertisements varied to account for the different requirements of each State’s consumer-protection laws, a point plaintiffs acknowledge but cannot overcome. “Other than variations to ensure compliance with consumer regulations of the different states,” they say, “the advertisements that were published [in various local newspapers] were substantially the same.” Plaintiffs’ Br. at 12. The key words are “[o]ther than” and “substantially,” and these qualifications show that the plaintiffs’ claims are not even linked by a common advertisement. Variations designed to account for differences in the applicable laws not only might suggest that the defendants were trying to comply in different ways with their legal obligations in each State, but they also confirm the varied nature of the claims, injuries and defenses. Even if, as the plaintiffs claim, callers heard identical sales pitches, Internet visitors saw the same website and purchasers received the same fulfillment kit, these similarities establish only that there is some factual overlap, not a predominant factual overlap among the claims and surely not one sufficient to overcome the key defect that the claims must be resolved under different legal standards.
Reason three: this conclusion is consistent with decisions of this court and several others. In a case involving negligence claims against a prosthetics manufacturer, we refused to allow a nationwide class covered by the laws of different States. “If more than a few of the laws of the fifty states differ,” we explained, “the district judge would face an impossible task of instructing a jury on the relevant law.”
In re Am. Med. Sys., Inc.,
The plaintiffs’ other objection to the district court’s class-action ruling goes to the timing, not the substance, of it. Given more time and more discovery, they say, they would have been able to poke holes in the court’s class-certification analysis. We think not.
That the motion to strike came before the plaintiffs had filed a motion to certify the class does not by itself make the court’s decision reversibly premature. Rule 23(c)(1)(A) says that the district court should decide whether to certify a class “[a]t an early practicable time” in the litigation, and nothing in the rules says that the court must await a motion by the plaintiffs. As a result, “[ejither plaintiff or defendant may move for a determination of whether the action may be certified under Rule 23(c)(1).” 7AA Charles Allen Wright et al.,
Federal Practice and Procedure
§ 1785;
see also, e.g., Vinole v. Countrywide Home Loans, Inc.,
To say that a defendant may freely move for resolution of the class-certification question whenever it wishes does not free the district court from the duty of engaging in a “rigorous analysis” of the question, and “sometimes it may be necessary for the court to probe behind the pleadings before coming to rest on the certification question.”
Gen. Tel. Co. v. Falcon,
That leaves one final point. After the district court granted the motion to strike the class allegations, it dismissed the action without prejudice for lack of jurisdiction. The jurisdictional determination is mistaken.
See Metz v. Unizan Bank,
III.
For these reasons, we affirm the district court’s judgment striking the class allegations and dismissing this lawsuit without prejudice against both defendants.
