*260 OPINION OF THE COURT
Stephen Lieata appeals the district court’s dismissal of his suit, which it treated as alleging a breach of contract, against the United States Postal Service for lack of subject matter jurisdiction. We conclude that we must reverse in light of Congress’s specific grant to the district courts of original jurisdiction over such claims.
I.
FACTS AND PROCEDURAL HISTORY
Because the district court dismissed the complaint under Federal Rule of Civil Procedure 12(b)(1) before the Postal Service filed an answer, we review only whether the allegations on the face of the complaint, taken as true, allege facts sufficient to invoke the jurisdiction of the district court.
See Haydo v. Amerikohl Mining Inc.,
According to the complaint, the Postal Service has established a program which encourages employee participation by awarding 10% of the total economic benefit of any implemented suggestion, up to a maximum award of $35,000. Lieata, a machinist employed by the Postal Service, submitted a suggestion in July 1989 for a modified roller for one of the Service’s package sorters. Li-cata’s suggestion was implemented at the local level and research indicated that if implemented nationwide, the modified roller could save the Service $500,000 in the first year. Although the modification was formally disapproved for national implementation in June 1991, Lieata claims that the Service continued to authorize the manufacture and use of the rollers without paying him his share of the savings.
On March 31, 1993, Lieata filed suit in the District Court for the District of New Jersey seeking $35,000 damages, as well as interest, costs, and attorney’s fees. He alleged jurisdiction under 39 U.S.C. § 409(a) (1988) and 28 U.S.C. § 1339 (1988). Both parties and the district court read the complaint to allege some kind of common law breach of contract claim. App. at 16 n. 3, 73-74, 159. The Service filed a Motion to Dismiss or, in the Alternative, for Summary Judgment prior to filing an answer, arguing that the district court lacked subject matter jurisdiction, that the complaint failed to state a claim upon which relief could be granted, or that summary judgment should be entered based on the affidavit and exhibits attached to the motion.
The district court dismissed the complaint for lack of subject matter jurisdiction, reasoning that section 409(a) was insufficient to maintain jurisdiction without a cause of action, and that if the claim sounded in contract it was barred by the Tucker Act.

DISCUSSION
A.
Section 409 of the Postal Reorganization Act of 1970, entitled “Suits by and against the Postal Service,” provides:
(a) Except as provided in section 3628 of this title [governing appeals of postal rate-making], the United States district courts shall have original but not exclusive jurisdiction over all actions brought by or against the Postal Service. Any action brought in a State court to which the Postal Service is a party may be removed to the appropriate United States district *261 court under the provisions of chapter 89 of title 28.
39 U.S.C. § 409(a) (1988).
When interpreting a statute we look first to its plain meaning, and if the language is unambiguous no further inquiry is necessary.
See Sacred Heart Medical Ctr. v. Sullivan,
Nor is there anything in our precedents that prevents us from attributing to section 409(a) its plain meaning. We have described section 409(a) as a “general grant of jurisdiction to the district courts,”
Air Courier Conference of America v. United States Postal Serv.,
Indeed, most courts of appeals to consider the question have found that section 409(a) is what it seems to be — a grant of jurisdiction to the district courts for suits in which the Postal Service is a party.
See, e.g., Continental Cablevision,
Despite the clear language and considerable precedent, there is a split of authority in the circuits as to whether section 409 provides an independent basis for subject matter jurisdiction.
See Hexamer v. Foreness,
We believe the Postal Service conflates the issues of subject matter jurisdiction, sovereign immunity, and a valid cause of action. Section 409(a) does not speak to sovereign immunity. It is 39 U.S.C. § 401(1) that waives the Service’s sovereign immunity by providing that it may “sue and be sued in its official name.”
See Loeffler v. Frank,
Further, we believe that the Postal Service’s argument, relying on
Peoples Gas,
that subject matter jurisdiction is absent without a cause of action is “seriously flawed” because “whether or not ‘a cause of action’ exists goes to the merits, not to the question of subject-matter jurisdiction.”
Continental Cablevision,
Jurisdiction, therefore, is not defeated as respondents seem to contend, by the possibility that the averments might fail to state a cause of action on which petitioners could actually recover. For it is well settled that the failure to state a proper cause of action calls for a judgment on the merits and not for a dismissal for want of jurisdiction. Whether the complaint states a cause of action on which relief could be granted is a question of law and just as issues of fact it must be decided after and not before the court has assumed jurisdiction over the controversy. If the court does later exercise its jurisdiction to determine that the allegations in the complaint do not state a ground for relief, then dismissal of the case would be on the merits, not for want of jurisdiction.

Thus, after reviewing the language and history of the statute, we hold that absent some other statutory bar, section 409(a) grants district courts subject matter jurisdiction over actions to which the Postal Service is a party.
B.
Nor do we agree with the district court’s alternative holding that the Tucker Act precludes subject matter jurisdiction over this suit.
The Tucker Act is one of the few places in the federal statutes which provides both jurisdiction and a waiver of sovereign immunity for non-tort actions against the United States and it generally requires recourse to the Court of Federal Claims.
See Bowen v. Massachusetts,
However, it is well settled that a claim brought against the Postal Service in its own name is not a claim against the United States and thus is not governed by the Tucker Act.
See Continental Cablevision,
The Federal Circuit, the court of appeals that probably spends the most time mastering the intricacies of jurisdiction under the Tucker Act, has noted the unusual position of the Postal Service in., that “in contradistinction to other federal entities, [it] may sue and be sued on contract claims in courts other than the Court of Federal Claims.”
Benderson Dev. Co. v. United States Postal Serv.,
It follows that we must reverse the district court’s Rule 12(b)(1) dismissal without precluding the Postal Service from either raising new Rule 12(b)(1) objections if appropriate on remand or proceeding to press its Rule 12(b)(6) motion. See Fed.R.Civ.P. 12(b)(6). We caution that our decision rests only on subject matter jurisdiction. We do not imply that we have found Licata’s claim viable, or that we have rejected the Service s arguments that go to that issue. 7
III.
CONCLUSION
For the foregoing reasons, we will reverse the order of the district court dismissing plaintiffs suit for lack of subject matter jurisdiction and remand for proceedings consistent with this opinion.
Notes
. Because of our interpretation of section 409(a), we need not address whether jurisdiction would be proper under 28 U.S.C. § 1339.
. The district courts of this circuit are also divided over the meaning of section 409(a).
Compare Hudak v. United States Postal Serv.,
No. Civ.A. 94-0007,
. Although we believe the statutory language alone is sufficient to overcome the Service’s argument, we note that the scant legislative history of this provision "refute[s] any argument that a literal construction of [section 409(a)] is so absurd or illogical that Congress could not have intended it.”
Conroy v. Aniskoff,
-U.S. • — —, -,
. Also irrelevant to the jurisdictional question is whether a private right of action exists under the Postal Reorganization Act,
see Gaj v. United States Postal Serv.,
. The district court did not have jurisdiction over this suit under the Little Tucker Act because Lieata sought the sum of $35,000 in his complaint.
. In the course of the oral argument, the court sua sponte raised the possibility that the Contract Disputes Act of 1978 (CDA), 41 U.S.C. §§ 601-13 (19.58 & Supp. IV 1992), would bar the district court’s jurisdiction. Although we are free to reach subject matter jurisdiction issues, and indeed are obliged to, even if they were not considered by the district court, if it is clear that the court lacked jurisdiction, this is not such a case. In the first place, the parties did not raise nor did they brief the applicability of the Contract Disputes Act. Therefore, if the Service believes it appropriate, it is free to raise this issue in the district court, or, of course, that court may raise the issue sua sponte.
In the second place, the Contract Disputes Act's only express limitation on district court jurisdiction is effected by its amendment of the Little Tucker Act to withdraw the district court's concurrent jurisdiction over those contract claims for sums not exceeding $10,000 that would otherwise be subject to the CDA,
See
28 U.S.C. § 1346(a)(2). Two circuits, after careful consideration, have held that where there is an independent basis for district court jurisdiction (as there is for claims against the Postal Service), both the Contract Disputes Act and the Tucker Act are irrelevant.
See In re Liberty Constr.,
. The Postal Service urges us to affirm the district court, inter alia, because Licata's claim was an aspect of a collective-bargaining agreement and therefore the complaint failed to state a claim upon which relief could be granted. It appears that much of its argument rests on affidavits and exhibits introduced in the district court, as distinguished from the facts alleged in the complaint. This would necessarily require a summary judgment decision, something we are not prepared to rule on in the first instance.
