Opinion for the court by Circuit Judge HENDERSON.
In this аppeal, Joseph Peters challenges the district court’s dismissal of his suit against the National Railroad Passenger Corporation (Amtrak) for injuries arising out of a train derailment as well as its denial of his motion for relief from the dismissal order. The district court concluded that Peters was bound by a settlement in a class action filed in the Eastern District of Pennsylvania. We affirm.
I.
On the night of January 29, 1988, Peters was a passenger on the “Night Owl,” a train operated by Amtrak between Washington, D.C. and Boston, Massachusetts. While operating in the vicinity of Chester, Pennsylvania, the “Night Owl” collided with a ballast regulator, a pieсe of maintenance equipment travelling on the same track, and derailed, injuring Peters and other passengers. Peters and others were admitted to Sacred Heart Medical Center (Sacred Heart) in Chester, Pennsylvania for treatment.
Thereafter, on March 1, 1988, a class action suit, сaptioned Sala v. National R.R. Passenger Corp., No. 88-1572 (E.D.Pa. Mar. 1, 1988), was filed on behalf of the injured passengers in the federal district court for the Eastern District of Pennsylvania. Oh April 29, 1988, the district court certified the class and directed Amtrak to provide a passenger list to the class counsel. Amtrak compiled the list from Sacred Heart’s records on the injured passengers. The records included progress notes listing Peters’ address as “930 Wes-tend Avenue, New York, NY.” 1 It did not provide Peters’ apartment number or zip code. 2
At the district court’s direction, class counsel sent to the class members, by first class mail, a notice of pendency of class action on August 26, 1988, and a notice of proposed settlement on July 28, 1989. Peters maintains he received neither notice. *1485 On September 27, 1989, the district court approved the settlement agreement and on April 23,1990, it issued an order dismissing the class action with prejudice.
On January 4, 1991, Peters sued Amtrak in the federal district court for the District of Columbia seеking $500,000 in compensatory and $1,000,000 in punitive damages for the injuries he sustained in the train wreck. Amtrak moved for judgment on the pleadings under Fed.R.Civ.P. 12(c) asserting the defense of res judicata. Amtrak argued that Peters was bound by the settlement in the class action because he was a member of the class and had not optеd out. Peters argued that he was not bound because he had not received notice.
The district court granted Amtrak’s motion holding that due process required only that Amtrak use its “best efforts” and did not “guarantee ... actual notice.” District Court Memorandum at 6. The district court further held that Amtrak’s “attempts to notify [Peters] of the pendency of the class action were reasonable” and that Peters was bound by the settlement. Id. at 6-7.
Thereafter, on April 19, 1991, Peters moved under Fed.R.Civ.P. 60(b) for relief from the district court’s order. Peters argued that he had just received from the hospital the emergency department record whiсh included his apartment number. Peters also pointed to an Amtrak Injury/Illness Report he had submitted to Amtrak’s New York office to argue that Amtrak had misled the court about its knowledge of his address. On May 24, 1991, the district court denied the motion without opinion.
Peters now appeals arguing that Amtrak had a duty to use reasonable efforts in providing class counsel with the passengers’ names and addresses which duty it breached when it provided an incomplete address for Peters. We note that in his opposition to Amtrak’s motion to dismiss, Peters argued that Amtrak had a duty under both the due process clause and rule 23 of the Federal Rules of Civil Procedure to provide the best notice practicable. Peters claimed below that Amtrak breached that duty when the notices were mailed to his Manhattan address without an apartment number and with an incorrect zip code.
II.
A. Standard of Review
We review the district court’s grant of Amtrak’s rule 12(c) motion
de novo. See International Paper Co. v. Town of Jay,
B. Peters’ Inadequate Notice Claim
Where, as here, a class action is maintainable because common questions of law or fact predominate,
see
Fed.R.Civ.P. 23(b)(3), rule 23 requires that “the court ... direct to the members of the class the best notice practicable under the circumstances, including individual notice to all members who сan be identified through reasonable efforts.” Fed.R.Civ.P. 23(c)(2).
*1486
The rule provides that “[individual notice must be sent to all class members whose names and addresses may be ascertained through reasonable effort.”
Eisen v. Carlisle & Jacquelin,
It is beyond dispute that notice by first class mail ordinarily satisfies rule 23(c)(2)’s requirement that class members receive “the best notice practiсable under the circumstances.”
See, e.g., Eisen,
We reject Peters’ argument. While
Mul-lane
and
Eisen
require that each individual identifiable “through reasonable effort” receive notice, their endorsement of first class mail as the means of accomplishing that notice as well as their emphasis on “notice
reasonably calculated
... to apprise interested parties,”
Mullane,
We thus turn to the question whether the notices mailed to Peters were “reasonably calculatеd” to notify him of the class action notwithstanding the address did not include his apartment number and used an incorrect zip code. We are not prepared to say as a matter of law that the omission of Peters’ apartment number and zip code rendered the notices not “reasonably calculated under all the circum *1487 stances” to notify him. With respect to the zip code, it was class counsel not Amtrak who added the incorrect zip code. We note that under section 122.32 of the U.S. Postal Service Domestic Mail Manual, the use of a zip code remains voluntary. See United States Postal Service Domestic Mail Manual § 122.32, at 55 (Mar. 1992). While a zip code undoubtedly adds to the preciseness of an address, we doubt that its use would remain voluntary if its omission rendered the mail not reasonably calculated to reach its destination.
Class counsel’s error, however, does not affect our analysis. We do not believe thаt such an error was foreseeable by Amtrak and can fathom no reason that Amtrak should bear the burden of it. Class counsel was, after all, appointed to represent Peters; his putative negligence is not an adequate basis to disturb Amtrak’s settled expectation of the finality of the class action. If, for example, Peters had failed to receive the notices because the post office lost them, Peters would have no argument that he was denied due process. Yet Amtrak had no more control over the actions of class counsel than it has over the actions of the post office.
It might be argued that Peters’ claim is distinguishable because, unlike the postal service, class counsel is subject to the control of the court and under rule 23(c)(2), it is ultimately the court’s responsibility to ensure that due process is provided. But the court must also ensure that Amtrak’s due process rights are not violated. As the Supreme Court has noted, “ ‘the doctrine of
res judicata
is not a mere matter of practice and procedure inherited from a more technical time than ours. It is a rule of fundamental and substantial justice, “of public policy and of privatе peace,” which should be cordially regarded and enforced by the courts....’”
Federated Dep’t Stores, Inc. v. Moitie,
As for mailing the notices without Peters’ apartment number, we cannot say that it was reasonably foreseeable to those preparing either the address list (Amtrak) or the mailings (class counsel) that Peters’ address was incomplete. Unless they had particularized knowledge that 930 West End Avenue was a high rise apartment house or was located in an area of apartment houses, they would not have a reasonable basis for believing that the address was incomplete. Acсordingly, we conclude that the absence of Peters’ apartment number did not render the notices not “reasonably calculated” to inform him of his rights.
III.
We next turn to Peters’ rule 60(b) motion based on his assertion that Amtrak was duty-bound to use reasonable efforts to provide class counsel with the passengers’ addresses as ordered by the district court in
Sala.
The
Sala
court ordered Amtrak to “furnish to plaintiff a list of the names and addresses of all passengers on the Night Owl.”
See Sala v. Amtrak,
No. 88-1572,
We need not decide the questions whether Amtrak had a duty to use reasonable efforts in compiling the address list and whether it breached that duty with respect to Peters. The
Sala
court, not the district court below, is the proper court to interpret and enforce its own order and we conclude
*1488
that the district court properly declined to consider this argument. While the court might have entertained a timely motion to transfer to the Eastern District of Pennsylvania under 28 U.S.C. § 1404(a) or arguably a motion to dismiss on the ground of
forum non conveniens, see, e.g., Piper Aircraft Co. v. Reyno,
IV.
In summary, we affirm the district court’s grant of Amtrak's motion to dismiss on the ground that the mailed notices, despite the absence of Peters’ apartment number and zip code from his mailing address, were “rеasonably calculated” to apprise him of the class action. We also affirm the district court’s denial of Peters’ rule 60(b) motion and decline to decide whether Amtrak failed to use reasonable efforts in compiling the address list. Accordingly, the district court’s dismissal is
Affirmed.
Notes
. Amtrak did not use the hospitаl’s emergency department record which contained more detailed information than the progress notes. See J.A. 126-128 (affidavit of David Dawson). In Peters' case, the emergency department record contained his address, including his apartment number, and a telephone number. While the district court made no such finding, the record suggests that the emergency department record could not be released without Peters' written authorization. See J.A. 209 (affidavit of Phyllis Newon).
Peters also alleges that several days after the accident, he submitted an Amtrak Injury/Illness Report to Amtrak's New York office, setting forth his full address. Amtrak disputеs this. Peters did not produce this document until his rule 60(b) motion for relief from the order and did not explain why the document was not produced earlier.
. While the passenger list Amtrak provided did not include Peters' zip code, the record shows that class counsel added a zip code, albeit an inсorrect one.
. This is not to say that Peters should be without a remedy. Rather, we simply believe that to the extent Peters’ claim is actionable, his redress, if any, should come from those responsible for causing his harm.
See, e.g., Zimmer Paper Prods., Inc. v. Berger & Montague P.C.,
. Peters did not present either the
Sala
order or the claims form to the district court in his opposition to Amtrak’s motion to dismiss but instead waited until his rule 60(b) motion for relief from the district court’s dismissal. In that motion, however, Peters did not set forth an adequate basis for relief.
See
Fed.RXiv.P. 60(b) (providing,
inter alia,
for relief for "mistake, inadvertence, surprise, or excusable neglect," "newly discovered evidence" and "fraud”). It was incumbent on Peters to make such a showing. Even if we assumed that Peters sought relief on the basis that the materials were "newly discovered evidence,” Peters made no showing that they could not have been diligently discovеred in time to be included in his opposition to Amtrak’s motion to dismiss.
See, e.g., Cloverleaf Standardbred Owners Ass’n v. National Bank of Washington,
Moreover, had we reached these issues, we note that Peters would be hard put to prove causation. The claims form Peters submitted to Amtrak lists his apartment number as 31 A; the affidavit Peters submitted in supрort of his opposition to Amtrak’s motion to dismiss lists his apartment number as 41E and does not state that he moved following the accident. Thus, even if Amtrak had included the apartment number from Peters' claim form on the address it gave to class counsel, the mailing would have been sent to the wrong address.
