ORDER RE: PLAINTIFF’S REQUEST FOR ENTRY OF DEFAULT and DEFENDANTS’ MOTION TO DISMISS

I. INTRODUCTION

This case involves a contract dispute between plaintiff Hickory Travel Services (“HTS” or “Plaintiff’), an American corporation, and TUI AG, a large German Corporation, several of its subsidiaries, and a joint venture partly owned by TUI AG. Plaintiff served process upon TQ3 Maritz Americas, Inc, the other owner of the joint venture, and upon two American subsidiaries of TUI AG. Plaintiff now moves for default against defendants TUI AG, TUI Business Travel Deutschland GmbH, TUI Leisure Travel Management Holding GmbH, and First Travel Management International GmbH (collectively referred to as the “TUI Defendants”). The TUI Defendants claim that they have not been properly served, and move to dismiss the complaint or, in the alternative, to quash the service of process. For the following reasons, the Court finds that service was insufficient and grants the TUI Defendants’ motion to quash service.

II. BACKGROUND

This action originated with an alleged breach of contract. Plaintiff alleges that it contracted to provide services to a company called First Travel Management Services. Shortly after reaching this agreement, First Travel Management Services was purchased by Preussag AG, which later renamed itself TUI AG. In 2000, TUI AG, according to HTS, liquidated First Travel Management Services, breaching First Travel’s contract with HTS. HTS initiated legal action in Germany against TUI AG. That action was settled. As part of the settlement, TUI AG’s subsidiaries were to use HTS’s services. In September, 2002, TUI Business Travel, TUI Leisure Travel, and First Travel Management Inc. announced to HTS that they were terminating the settlement, whereupon HTS filed this action.

HTS initiated the action by attempting to serve process upon four entities. The first, Feralloy Corporation, is a steel manufacturing company. The second, Hapag-LIoyd (America) Inc., is a shipping company. Both Hapag-LIoyd (America) and Feralloy do business in California and were served through an authorized agent in California. HTS also attempted to serve process upon TQ3 Travel Solutions GmbH, a German corporation, and TQ3 Maritz Americas, a Missouri corporation doing business in Missouri. HTS attempted to serve both of these entities by serving Mary Barrows, a payroll clerk for TQ3 Maritz Americas in Missouri.

The corporate relationships between the served entities and the named defendants are complicated and subject to some dispute. *550 The parties agree that defendant TUI AG wholly owns Feralloy Corporation and Ha-pag-Lloyd (America) Inc. TQ3 Travel Solutions GmbH appears to be a joint venture, with a wholly owned subsidiary of TUI AG owning half and TQ3 Maritz Americas Inc., an entirely separate company, owning the other half. Beyond those general agreements, however, the parties dispute the exact nature of the corporate connections. HTS argues that Hapag Lloyd (America), Inc., Feralloy Corporation, TQ3 Travel Solutions GmbH, and, apparently, TQ3 Maritz Americas Inc. are all effectively part of the same giant TUI AG corporation, and that service on those parts constitutes service on both the whole and the other parts. Defendants, however, argue that each division, though owned wholly or in part by TUI AG, maintains a separate corporate identity and that service on the U.S. divisions does not constitute service on the named defendants. Moreover, Defendants argue that TQ3 Maritz Americas is an entirely separate company incapable of receiving service on behalf of the TUI Defendants, and that TQ3 Travel Solutions GmbH has not yet been properly served.

Accurately describing the corporate structure is a task better suited for a diagram than for words. The following figure, taken from the declaration of Cornelius L. McGrath submitted in support of Defendants’ reply brief, provides a partial summary of the structural relationship between TUI AG, its subsidiaries, and TQ3 Travel Solutions GmbH.

III. LEGAL STANDARD

A. Burden of Proof

A party must be properly served for the Court to obtain personal jurisdiction over that party. If the sufficiency of service is challenged, “the party on whose behalf service was made... has the burden to establish its validity.” Wishart v. Agents for International Monetary Fund Internal Revenue Service, 1995 WL 494586 at *2 *552 (N.D.Cal.1995). “Although Rule 4 is to be construed liberally, service is not effective unless a plaintiff has substantially complied with its requirements.” Id.

B. Sufficiency of Process

The sufficiency of process in federal courts is determined by Rule 4 of the Federal Rules of Civil Procedure. Rule 4 sets forth several ways for serving a foreign corporation. First, Rule 4(f)(1) provides that service may be accomplished in accordance with the procedures of the Hague Convention. If, however, the corporation has sufficient contacts with the United States that service may be completed within the United States, the Hague Convention’s requirements for international service do not apply. Volkswagen-werk Aktiengesellschaft v. Schlunk, 486 U.S. 694 , 108 S.Ct. 2104 , 100 L.Ed.2d 722 (1988) (holding that since Illinois law defined service as complete within the United States, the Hague Convention did not apply). The corporation then may be served in accordance with Rule 4(h)’s standard provisions for serving a corporation.

Rule 4(h) provides two ways of effecting service. First, Rule 4(h) states that service may be accomplished in accordance with Rule 4(e)(1), which allows service according to the procedures of the state in which the federal court sits. Second, service may be accomplished “by delivering a copy of the summons and of the complaint to an officer, a managing or general agent, or to any other agent authorized by appointment or by law to receive service of process and, if the agent is one authorized by statute to receive service and the statute so requires, by also mailing a copy to the defendant.” Fed. R. Civ. Proc. 4(h)(1).

Thus, determining whether service outside the Hague Convention is possible involves a two-part inquiry. First, the Court must determine whether state law procedures, as incorporated under Rule 4(e)(1) and limited by due process, allow for completed service within the state. Under this inquiry, state law on serving corporations is crucial, for it is state law that defines whether service has been completed within the United States. Schlunk, 486 U.S. at 706-08 , 108 S.Ct. 2104 ; Graval v. P.T. Bakrie & Bros., 986 F.Supp. 1326, 1330-31 (C.D.Cal.1996) (disapproved on other grounds by Rio Properties, Inc. v. Rio Intern. Interlink, 284 F.3d 1007 (9th Cir. 2002)). Federal law, in the form of due process limitations, may become relevant if state law is highly permissive in allowing service, see Schlunk at 707, 108 S.Ct. 2104 , but where state law is restrictive federal law cannot create a mechanism for service under Rule 4(e)(1).

California state law provides specific, limited methods for service of process upon corporations. California Corporations Code § 1505 requires all corporations doing business in California to designate agents to receive service of process. California Code of Civil Procedure § 416.10 sets forth who within a corporation may be served, and generally limits service to the heads of the corporation or to those persons designated by the corporation to receive it. Federal courts interpreting these provisions have found them to create no procedure for serving a foreign corporation by serving its domestic subsidiary. Graval, 986 F.Supp. at 1330 (“Under California law, service on a subsidiary does not constitute service on a parent corporation, even if the subsidiary is considered to be an ‘alter-ego’ of the parent corporation.”); Orion Tire Corp. v. General Tire, Inc., 1992 WL 295224 at *1 (C.D.Cal.1992) (distinguishing Schlunk because “California does not have a provision allowing for substituted service upon a subsidiary corporation... California law requires service only on those authorized to accept service.”).

If state law does not allow for service of process, the Court still must determine whether service may be completed under the alternative method described in the above-quoted text from Rule 4(h)(1). In order to perform this analysis, the Court must determine whether the right corporate entity was served. Other federal courts addressing this issue have used jurisdictional analysis to determine whether service on a subsidiary counts as service upon its parent. Gallagher v. Mazda Motor of America, 781 F.Supp. 1079 , 1083 n. 8 (E.D.Pa.1992) (noting that federal courts use such an analysis even if *553 they do not explicitly describe it as such). 1 Under this analysis, the Plaintiff must demonstrate either that the subsidiary functions as the parent’s agent or as its alter ego. Id. at 1083-85 ; Akzona v. E.I. Du Pont De Nemours & Co., 607 F.Supp. 227, 237 (D.Del. 1984). 2

For purposes of jurisdictional analysis, a subsidiary functions as the parent’s agent if it accomplishes tasks that the parent in its absence would have to accomplish itself. Doe v. Unocal, 248 F.3d 915 , 928 (9th Cir.2001); Gallagher, 781 F.Supp. at 1083-84 . In other words, if the subsidiary functions as an indispensable part of the parent’s business, it is the parent’s agent. Id. The fact that the subsidiary performs a function that the parent finds useful, or that the subsidiary makes money for the parent, is insufficient to establish agency if the parent could carry on its core business in the absence of that subsidiary’s work; for agency to exist, the subsidiary’s activity must be integral to the parent’s business. See Gallagher at 1085 (noting that a holding company’s investments weren’t necessarily its agents, since the holding company could divest of those investments and still be a holding company).

A subsidiary functions as the parent’s alter ego if the subsidiary is so intertwined with the parent that it functions as part thereof, and if disregarding that unity of interest would result in fraud or injustice. See Doe v. Unocal, 248 F.3d at 925. The federal courts have generally respected corporate efforts to maintain separate identities, and will not pierce the formalities of separation merely because of a showing of complete ownership. Wright & Miller, Federal Practice & Proc. § 1104. The parent corporation may even direct some of the activities of the subsidiary, and report the subsidiary’s income as its own, without having separate corporate identities be disregarded. Id. at 925-27; Akzona, 607 F.Supp. at 238 .. If, however, the parent is involved in directing the day-to-day management of the subsidiary, or if the management of the parent and subsidiary is so intertwined that separation is merely a fiction, a court may disregard the formalities of separation and consider service on the subsidiary to be service upon the parent. Unocal, 248 F.3d at 925-26.

C. Remedies for Insufficient Service

If service is insufficient, the Court may either dismiss the case or retain jurisdiction but quash service. So long as there is a chance that the plaintiff still could accomplish service, the latter remedy is preferred. Umbenhauer v. Woog, 969 F.2d 25, 30 (3rd Cir.1992). The Court also has discretion to order jurisdictional discovery where jurisdictional facts are in dispute or more factual basis is needed. nMotion, Inc. v. Environmental Tectonics Corp., 196 F.Supp.2d 1051, 1055 (D.Or.2001).

IV. DISCUSSION

A. Sufficiency of Process

In order to prove that Defendants were properly served, Plaintiff must illustrate that a series of purportedly separate corporations *554 are in fact bound by continuous chains of either agency or alter-ego relationships. To show that TUI AG was properly served, for example, Plaintiff must show either 1) that Hapag-Lloyd (America), Inc. is the alter ego or agent of Hapag-Lloyd Container Linie GmbH, that Hapag-Lloyd Container Linie GmbH is the alter ego or agent of Hapag-Lloyd AG, and that Hapag-Lloyd AG is the alter ego or agent of TUI AG; 2) that a similar chain of connection exists connecting Feralloy Corporation through its parents to TUI AG; 3) that a similar chain of connection binds TQ3 Maritz Americas 3 to TUI AG, or 4) that any of these served companies are in fact directly the agent of TUI AG even in the absence of a chain connecting them through their parents. To demonstrate that the other TUI defendants were properly served, Plaintiff needs to demonstrate either a chain beginning with TQ3 Maritz Americas and moving upward through TQ3 Travel Solutions GmbH or that, in addition to TUI AG being properly served through Hapag-Lloyd (America) or Feralloy Corporation, the remaining TUI defendants are the alter egos or agents of TUI AG.

Any of these showings would be rather complicated, necessitating discussion of a series of corporate connections. In seeking to show the requisite connections, Plaintiff relies primarily on general arguments about the TUI group as a whole. These arguments, however, do not suffice to show that TUI AG’s divisions are alter egos for TUI AG itself or TUI AG’s agents. Plaintiffs arguments with respect to the TQ3 Maritz Americas are even more convoluted and incomplete, with companies inconsistently named and connections only partially described.

The crux of Plaintiffs alter ego argument is based on the facts that TUI AG wholly owns its subsidiaries, refers to them as divisions and not separate companies, reports their earnings in annual statements, boasts of corporate integration, and has made decisions about restructuring the businesses of some of those subsidiaries. All of these assertions are relevant to alter ego status, but even in combination they do not suffice to make a prima facie case of alter ego relationships. See Unocal, 248 F.3d at 925-27. Plaintiff has not shown that management structures are interchangeable and has made only admittedly speculative claims, without any evidentiary support, that TUI AG is involved in the day-to-day management of its subsidiaries. These general allegations do not suffice to show that the TUI corporate structure is in fact one integrated company.

Plaintiffs agency arguments are similarly incomplete. Plaintiff suggests that each division is an agent of TUI AG because in those divisions’ absence TUI AG would have to use its own employees to carry on the substantial amounts of business that those divisions provide. To show agency in this context, however, Plaintiff must show that TUI AG could not carry on its own business — not just that it would lose the business of those divisions — in those divisions’ absence. Unocal, 248 F.3d at 928-29; Gallagher, 781 F.Supp. at 1085 . Plaintiffs argument overlooks the possibility that TUI might simply ignore the markets those divisions serve. Plaintiff has made no showing that TUI AG — which characterizes itself solely as a holding company — would be unable to properly function if it divested of Feralloy Corporation’s manufacturing business or Hapag-Lloyd’s shipping business. Under Plaintiffs reasoning, basically any corporate division that makes money for the parent is an agent of the parent. The test of agency in this context is not nearly so broad.

Plaintiff has provided further evidence of agency or alter ego relationships only for a few connections within the TUI AG side of the overall corporate structure. Specifically, in addition to the general allegations already discussed, Plaintiff has asserted that Hapag-Lloyd (America) has received orders on behalf of Hapag-Lloyd Container Linie GmbH and that TUI AG made restructuring divisions about Hapag-Lloyd AG after purchas *555 ing it. 4 The relationship between Hapag-Lloyd (America), Inc. and Hapag-Lloyd Container Linie GmbH may establish an alter ego or agency relationship, but this is only one link in an otherwise unestablished chain,

Plaintiffs discussion of the TQ3 Maritz Americas Inc. side of the corporate tree is even more convoluted. Plaintiff argues that service upon TQ3 Maritz Americas constitutes service upon both TQ3 Travel Solutions GmbH and the TUI Defendants. 5 This argument apparently is based upon Plaintiffs belief that TQ3 Maritz Americas Inc., the TUI Defendants, and TQ3 Travel Solutions Inc. GmbH are all in fact one big company. TQ3 Maritz Americas Inc. and the TUI Defendants are under entirely separate ownership, however, and showing that they work together and are working closely with TQ3 Travel Solutions GmbH, their joint venture, is not the same as establishing an absence of corporate separation. Given the complexity of the corporate relationships and the similarity of the various entities’ names, Plaintiffs confusion is understandable, but nevertheless Plaintiff has not made a prima facie showing of service upon the TUI Defendants through service upon TQ3 Maritz Americas.

Thus, key links in each chain that might connect the served entities to the actual'defendants remain undemonstrated, and Plaintiff has not made a prima facie case that process has been properly served upon the TUI Defendants. Absent such a showing, the Court cannot grant Plaintiffs request for default.

B. Jurisdictional Discovery

In the absence of sufficient facts to demonstrate jurisdiction, the Court has discretion to allow jurisdictional discovery. Such discovery is typically allowed where an insufficient factual record exists or where key jurisdictional facts are contested. Here, an insufficient factual record does exist, but Plaintiff currently is so far, both in fact and in law, from asserting a prima facie case of proper service that the Court does not see jurisdictional discovery as merited.

C. Quashing Service

Although the Court may dismiss the case, quashing service is the typical remedy if initial defects in service might be corrected, and the Court chooses to quash service rather than to dismiss the case.

V. CONCLUSION

Because Plaintiff has not properly served the TUI Defendants, the Court orders service quashed. Plaintiffs motion for entry of default is DENIED.

IT IS SO ORDERED.

. Plaintiff does not concede that this analysis should be used, instead arguing that Schlunk establishes the principle that service on a wholly owned domestic subsidiary constitutes service upon its parent. Justice Brennan's concurrence does contain language suggesting that such service is possible, see Schlunk at 708, 108 S.Ct. 2104 , but the majority holding, which Justice Brennan was briefly summarizing, does not hold that such service is always sufficient. Instead, the majority held that where service on a domestic subsidiary was defined by Illinois law as constituting service upon its foreign parent, that service did not need to be completed in accordance with the Hague Convention. Id. at 706-07 , 108 S.Ct. 2104 . In other words, the Court assumed that such service was valid under Illinois law; it did not create a general federal precedent always allowing service on a foreign corporation through its wholly owned domestic subsidiary.

. California law also uses agency/alter ego analysis to determine whether a court may exercise jurisdiction over a defendant. See Sonora Diamond Corp. v. Superior Ct., 83 Cal.App.4th 523 , 99 Cal.Rptr.2d 824 (2000). This does not mean, however, that the California courts have folded that jurisdictional analysis into their analysis of the procedural sufficiency of process; procedural sufficiency still is measured under the more specific standards set forth in the California Code of Civil Procedure and the California Corporations Code. See Graval, 986 F.Supp. at 1330 ; Orion Tire Corp., 1992 WL 295224 at *1.

. Plaintiff apparently asserts that it has served TQ3 Travel Solutions GmbH, but the individuals served both work for TQ3 Maritz Americas, Inc.

. Some of Plaintiff’s asserted factual bases for its argument appear to be irrelevant. For example, Plaintiff attached to one declaration a newspaper article that purportedly showed that TUI was engaged in decisions regarding the management structure of its subsidiaries. Pevzner Decl. Exh. E. The article appears to be about TUI UK, which is not a party to this action or a link in any of the chains potentially connecting the served entities to the actual defendants.

. Plaintiff claims to have directly served TQ3 Travel Solutions GmbH, but the person it served' — Mary Burrows, a payroll clerk — works for TQ3 Maritz Americas, Inc.
