opinion: Justice Stevens
  delivered the opinion of the Court.
  In Edwards v. Arizona, 451 U. S. 477, 484-485 (1981), we held that a suspect who has “expressed his desire to deal with the police only through counsel is not subject to further interrogation by the authorities until counsel has been made available to him, unless the accused himself initiates further communication, exchanges, or conversations with the police.” In this case Arizona asks us to craft an exception to that rule for cases in which the police want to interrogate a suspect about an offense that is unrelated to the subject of their initial interrogation. Several years ago the Arizona Supreme Court considered, and rejected, a similar argument, stating:
  “The only difference between Edwards and the appellant is that Edwards was questioned about the same offense after a request for counsel while the appellant was reinterrogated about an unrelated offense. We do not believe that this factual distinction holds any legal significance for fifth amendment purposes. ” State v. Routhier, 137 Ariz. 90, 97, 669 P. 2d 68, 75 (1983), cert. denied, 464 U. S. 1073 (1984).
  We agree with the Arizona Supreme Court’s conclusion.

  On April 16, 1985, respondent was arrested at the scene of a just-completed burglary. The arresting officer advised him that he had a constitutional right to remain silent and also the right to have an attorney present during any interrogation. See Miranda v. Arizona, 384 U. S. 436, 467-479 (1966). Respondent replied that he “wanted a lawyer before answering any questions.” This fact was duly recorded in the officer’s written report of the incident. In due course, respondent was convicted of the April 16, 1985, burglary.
  On April 19, 1985, while respondent was still in custody pursuant to the arrest three days earlier, a different officer interrogated him about a different burglary that had occurred on April 15. That officer was not aware of the fact that respondent had requested the assistance of counsel three days earlier. After advising respondent of his rights, the officer obtained an incriminating statement concerning the April 15 burglary. In the prosecution for that offense, the trial court suppressed that statement. In explaining his ruling, the trial judge relied squarely on the Arizona Supreme Court’s opinion in State v. Routhier, 137 Ariz., at 97, 669 P. 2d, at 75, characterizing the rule of the Edwards case as “clear and unequivocal.”
  The Arizona Court of Appeals affirmed the suppression order in a brief opinion, stating:
  “In Routhier, as in the instant case, the accused was continuously in police custody from the time of asserting his Fifth Amendment right through the time of the impermissible questioning. The coercive environment never dissipated.” App. to Pet. for Cert. 24.
  The Arizona Supreme Court denied a petition for review. Id., at 25. We granted certiorari to resolve a conflict with certain other state court decisions. 484 U. S. 975 (1987). We now affirm.

  A major purpose of the Court’s opinion in Miranda v. Arizona, 384 U. S., at 441-442, was “to give concrete constitutional guidelines for law enforcement agencies and courts to follow.” “As we have stressed on numerous occasions, ‘[o]ne of the principal advantages’ of Miranda is the ease and clarity of its application. Berkemer v. McCarty, 468 U. S. 420, 430 (1984); see also New York v. Quarles, [467 U. S. 649, 662-664 (1984)] (concurring opinion); Fare v. Michael C., 442 U. S. [707, 718 (1979)].” Moran v. Burbine, 475 U. S. 412, 425 (1986).
  The rule of the Edwards case came as a corollary to Miranda's, admonition that “[i]f the individual states that he wants an attorney, the interrogation must cease until an attorney is present.” 384 U. S., at 474. In such an instance, we had concluded in Miranda, “[i]f the interrogation continues without the presence of an attorney and a statement is taken, a heavy burden rests on the government to demonstrate that the defendant knowingly and intelligently waived his privilege against self-incrimination and his right to retained or appointed counsel.” Id., at 475. In Edwards, we “reconfirmed] these views and, to lend them substance, emphasize[d] that it is inconsistent with Miranda and its progeny for the authorities, at their instance, to reinterro-gate an accused in custody if he has clearly asserted his right to counsel.” 451 U. S., at 485. We concluded that re-interrogation may only occur if “the accused himself initiates farther communication, exchanges, or conversations with the police.” Ibid. Thus, the prophylactic protections that the Miranda warnings provide to counteract the “inherently compelling pressures” of custodial interrogation and to “permit a full opportunity to exercise the privilege against self-incrimination,” 384 U. S., at 467, are implemented by the application of the Edwards corollary that if a suspect believes that he is not capable of undergoing such questioning without advice of counsel, then it is presumed that any subsequent waiver that has come at the authorities’ behest, and not at the suspect’s own instigation, is itself the product of the “inherently compelling pressures” and not the purely voluntary choice of the suspect. As Justice White has explained, “the accused having expressed his own view that he is not competent to deal with the authorities without legal advice, a later decision at the authorities’ insistence to make a statement without counsel’s presence may properly be viewed with skepticism.” Michigan v. Mosley, 423 U. S. 96, 110, n. 2 (1975) (concurring in result).
  We have repeatedly emphasized the virtues of a bright-line rule in cases following Edwards as well as Miranda. See Michigan v. Jackson, 475 U. S. 625, 634 (1986); Smith v. Illinois, 469 U. S. 91, 98 (1984) (per curiam); Solem v. Stumes, 465 U. S. 638, 646 (1984); see also Shea v. Louisiana, 470 U. S. 51 (1985); Oregon v. Bradshaw, 462 U. S. 1039, 1044 (1983) (plurality opinion) (Rehnquist, J.). In Fare v. Michael C., 442 U. S. 707, 718 (1979), we explained that the “relatively rigid requirement that interrogation must cease upon the accused’s request for an attorney . . . has the virtue of informing police and prosecutors with specificity as to what they may do in conducting custodial interrogation, and of informing courts under what circumstances statements obtained during such interrogation are not admissible. This gain in specificity, which benefits the accused and the State alike, has been thought to outweigh the burdens that the de-cisión in Miranda imposes on law enforcement agencies and the courts by requiring the suppression of trustworthy and highly probative evidence even though the confession might be voluntary under traditional Fifth Amendment analysis.” The Edwards rule thus serves the purpose of providing “clear and unequivocal” guidelines to the law enforcement profession. Surely there is nothing ambiguous about the requirement that after a person in custody has expressed his desire to deal with the police only through counsel, he “is not subject to further interrogation by the authorities until counsel has been made available to him, unless the accused himself initiates further communication, exchanges, or conversations with the police.” 451 U. S., at 484-485.

  Petitioner contends that the bright-line, prophylactic Edwards rule should not apply when the police-initiated interrogation following a suspect’s request for counsel occurs in the context of a separate investigation. According to petitioner, both our cases and the nature of the factual setting compel this distinction. We are unpersuaded.
  Petitioner points to our holding in Michigan v. Mosley, 423 U. S., at 103-104 (quoting Miranda v. Arizona, 384 U. S., at 479), that when a suspect asserts his right to cut off questioning, the police may “ ‘scrupulously honor’ ” that right by “immediately ceas[ing] the interrogation, resum[ing] questioning only after the passage of a significant period of time and the provision of a fresh set of warnings, and restrict[ing] the second interrogation to a crime that had not been a subject of the earlier interrogation.” 423 U. S., at 106. The police in this case followed precisely that course, claims the State. However, as Mosley made clear, a suspect’s decision to cut off questioning, unlike his request for counsel, does not raise the presumption that he is unable to proceed without a lawyer’s advice. See id., at 101, n. 7; id., at 110, n. 2 (White, J., concurring in result), quoted supra, at 681.
  Petitioner points as well to Connecticut v. Barrett, 479 U. S. 523, 525 (1987), which concerned a suspect who had “told the officers that he would not give a written statement unless his attorney was present but had ‘no problem’ talking about the incident.” We held that this was a limited request for counsel, that Barrett himself had drawn a distinction between oral and written statements and thus that the officers could continue to question him. Petitioner argues that Roberson’s request for counsel was similarly limited, this time to the investigation pursuant to which the request was made. This argument is flawed both factually and legally. As a matter of fact, according to the initial police report, respondent stated that “he wanted a lawyer before answering any questions.” As a matter of law, the presumption raised by a suspect’s request for counsel — that he considers himself unable to deal with the pressures of custodial interrogation without legal assistance — does not disappear simply because the police have approached the suspect, still in custody, still without counsel, about a separate investigation.
  That a suspect’s request for counsel should apply to any questions the police wish to pose follows, we think, not only from Edwards and Miranda, but also from a case decided the same day as Barrett. In Colorado v. Spring, 479 U. S. 564, 577 (1987), we held that “a suspect’s awareness of all the possible subjects of questioning in advance of interrogation is not relevant to determining whether the suspect voluntarily, knowingly, and intelligently waived his Fifth Amendment privilege.” In the face of the warning'that anything he said could be used as evidence against him, Spring’s willingness to answer questions, without limiting such a waiver, see Connecticut v. Barrett, supra, indicated that he felt comfortable enough with the pressures of custodial interrogation both to answer questions and to do so without an attorney. Since there is “no qualification of [the] broad and explicit warning” that “anything [a suspect] says may be used against him,” 479 U. S., at 577 (emphasis in original), Spring’s decision to talk was properly considered to be equally unqualified. Conversely, Roberson’s unwillingness to answer any questions without the advice of counsel, without limiting his request for counsel, indicated that he did not feel sufficiently comfortable with the pressures of custodial interrogation to answer questions without an attorney. This discomfort is precisely the state of mind that Edwards presumes to persist unless the suspect himself initiates further conversation about the investigation; unless he otherwise states, see Connecticut v. Barrett, supra, there is no reason to assume that a suspect’s state of mind is in any' way investigation-specific, see Colorado v. Spring, supra.
  Finally, petitioner raises the case of Maine v. Moulton, 474 U. S. 159, 161 (1985), which held that Moulton’s “Sixth Amendment right to the assistance of counsel was violated by the admission at trial of incriminating statements made by him to his codefendant, a secret government informant, after indictment and at a meeting of the two to plan defense strategy for the upcoming trial.” That case did not involve any Miranda issue because Moulton was not in custody. In our opinion, we rejected an argument that the statements should be admissible because the police were seeking information regarding both the crime for which Moulton had already been indicted, and a separate, inchoate scheme. Following Massiah v. United States, 377 U. S. 201, 207 (1964), we recognized, though, that the continuing investigation of uncharged offenses did not violate the defendant’s Sixth Amendment right to the assistance of counsel. Our recognition of that fact, however, surely lends no support to petitioner’s argument that in the Fifth Amendment context, “statements about different offenses, developed at different times, by different investigators, in the course of two wholly independent investigations, should not be treated the same.” Brief for Petitioner 32. This argument overlooks the difference between the Sixth Amendment right to counsel and the Fifth Amendment right against self-incrimination. The former arises from the fact that the suspect has been formally charged with a particular crime and thus is facing a state apparatus that has been geared up to prosecute him. The latter is protected by the prophylaxis of having an attorney present to counteract the inherent pressures of custodial interrogation, which arise from the fact of such interrogation and exist regardless of the number of crimes under investigation or whether those crimes have resulted in formal charges.
  In sum, our cases do not support petitioner’s position.

  Petitioner’s attempts at distinguishing the factual setting here from that in Edwards are equally unavailing. Petitioner first relies on the plurality opinion in Oregon v. Bradshaw, 462 U. S., at 1044 (Rehnquist, J.), which stated that Edwards laid down “a prophylactic rule, designed to protect an accused in police custody from being badgered by police officers in the manner in which the defendant in Ed wards was.” Petitioner reasons that “the chances that an accused will be questioned so repeatedly and in such quick succession that it will ‘undermine the will’ of the person questioned, or will constitute ‘badger[ing],’ are so minute as not to warrant consideration, if the officers are truly pursuing separate investigations.” Brief for Petitioner 16. It is by no means clear, though, that police engaged in separate investigations will be any less eager than police involved in only one inquiry to question a suspect in custody. Further, to a suspect who has indicated his inability to cope with the pressures of custodial interrogation by requesting counsel, any further interrogation without counsel having been provided will surely exacerbate whatever compulsion to speak the suspect may be feeling. Thus, we also disagree with petitioner’s contention that fresh sets of Miranda warnings will “reassure” a suspect who has been denied the counsel he has clearly requested that his rights have remained untrammeled. See ibid. Especially in a case such as this, in which a period of three days elapsed between the unsatisfied request for counsel and the interrogation about a second offense, there is a serious risk that the mere repetition of the Miranda warnings would not overcome the presumption of coercion that is created by prolonged police custody.
  The United States, as amicus curiae supporting petitioner, suggests that a suspect in custody might have “good reasons for wanting to speak with the police about the offenses involved in the new investigation, or at least to learn from the police what the new investigation is about so that he can decide whether it is in his interest to make a statement about that matter without the assistance of counsel.” Brief for United States as Amicus Curiae 11. The simple answer is that the suspect, having requested counsel, can determine how to deal with the separate investigations with counsel’s advice. Further, even if the police have decided temporarily not to provide counsel, see n. 6, supra, they are free to inform the suspect of the facts of the second investigation as long as such communication does not constitute interrogation, see Rhode Island v. Innis, 446 U. S. 291 (1980). As we have made clear, any “further communication, exchanges, or conversations with the police” that the suspect himself initiates, Edwards v. Arizona, 451 U. S., at 485, are perfectly valid.
  Finally, we attach no significance to the fact that the officer who conducted the second interrogation did not know that respondent had made a request for counsel. In addition to the fact that Edwards focuses on the state of mind of the suspect and not of the police, custodial interrogation must be conducted pursuant to established procedures, and those procedures in turn must enable an officer who proposes to initiate an interrogation to determine whether the suspect has previously requested counsel. In this case respondent’s request had been properly memorialized in a written report but the officer who conducted the interrogation simply failed to examine that report. Whether a contemplated reinterrogation concerns the same or a different offense, or whether the same or different law enforcement authorities are involved in the second investigation, the same need to determine whether the suspect has requested counsel exists. The police department’s failure to honor that request cannot be justified by the lack of diligence of a particular officer. Cf. Giglio v. United States, 405 U. S. 150, 154 (1972).
  The judgment of the Arizona Court of Appeals is
  Affirmed.
  Justice O’Connor took no part in the consideration or decision of this case.
  Tr. 26 (Apr. 3, 1986).
  “Routhier was based on Edwards versus Arizona which held that once the defendant has invoked his right to counsel, he may not be re-interrogated unless counsel has been made available to him or he initiates the conversation.
  “The Routhier court states that whether the defendant is re-interrogated about the same offense or an unrelated offense makes no difference for Fifth Amendment purposes.
  “The Routhier court further stated that Edwards is clear and unequivocal, there is to be no further interrogation by authorities once the right to counsel is invoked. The Court in that ease finding that the assertion of the right to counsel is an assertion by the accused that he is not competent to deal with authorities without legal advice. And that the resumption of questioning by the police without the requested attorney being provided, strongly suggests to the accused that he has no choice but to answer.” App. to Pet. for Cert. 15-16.
  See State v. Dampier, 314 N. C. 292, 333 S. E. 2d 230 (1985) (Edwards inapplicable to interrogation by authorities from different State concerning unrelated matter); McFadden v. Commonwealth, 225 Va. 103, 300 S. E. 2d 924 (1983) (Edwards inapplicable when authorities from different county question suspect about different crime); see also Lofton v. State, 471 So. 2d 665 (Fla. App.) (no Edwards violation when suspect is represented by attorney in unrelated matter, then questioned without counsel present), review denied, 480 So. 2d 1294 (Fla. 1985); State v. Newton, 682 P. 2d 295 (Utah 1984) (same); State v. Cornethan, 38 Wash. App. 231, 684 P. 2d 1355 (1984) (alternative holding: Edwards inapplicable to interrogation in unrelated investigation; court also holds that representation by attorney in unrelated matter does not suffice as request for counsel for Edwards purposes); cf. State v. Harriman, 434 So. 2d 551 (La. App.) (adopts petitioner’s view here, but only after holding that suspect had initiated conversation regarding second investigation), writ denied, 440 So. 2d 729 (La. 1983); but see United States ex rel. Espinoza v. Fairman, 813 F. 2d 117, 124-126 (CA7) (same rule as Arizona), cert. denied, 483 U. S. 1010 (1987); Luman v. State, 447 So. 2d 428 (Fla. App. 1984). (same); Radovsky v. State, 296 Md. 386, 464 A. 2d 239 (1983) (same); see also Boles v. Foltz, 816 F. 2d 1132, 1137-1141 (CA6) (Gibson, J., dissenting) (same; majority does not reach issue), cert. denied, 484 U. S. 857 (1987); cf. United States v. Scalf, 708 F. 2d 1540, 1544 (CA10 1983) (knowledge of request for counsel “is imputed to all law enforcement officers who subsequently deal with the suspect”); State v. Arceneaux, 425 So. 2d 740 (La. 1983) (same).
  It is significant that our explanation of the basis for the “per se aspect of Miranda” in Fare v. Michael C., 442 U. S., at 719, applies to the application of the Edwards rule in a case such as this. As we stated in Fare:
  “The rule in Miranda . . . was based on this Court’s perception that the lawyer occupies a critical position in our legal system because of his unique ability to protect the Fifth Amendment rights of a client undergoing custodial interrogation. Because of this special ability of the lawyer to help the client preserve his Fifth Amendment rights once the client becomes enmeshed in the adversary process, the Court found that ‘the right to have counsel present at the interrogation is indispensable to the protection of the Fifth Amendment privilege under the system’ established by the Court. [384 U. S.], at 469. Moreover, the lawyer’s presence helps guard against overreaching by the police and ensures that any statements actually obtained are accurately transcribed for presentation into evidence. Id., at 470.
  “The per se aspect of Miranda was thus based on the unique role the lawyer plays in the adversary system of criminal justice in this country.” 442 U. S., at 719.
  Tr. 26 (Apr. 3, 1986) (emphasis added); see id., at 23; Tr. 12 (Oct. 17, 1985, a.m.).
  The United States, as amicus curiae supporting petitioner, suggests similarly that “respondent’s failure to reiterate his request for counsel to [the officer involved in the second investigation], even, after [that officer] gave respondent complete Miranda warnings, could not have been the result of any doubt on respondent’s part that the police would honor a request for counsel if one were made.” Brief for United States as Amicus Curiae 10. This conclusion is surprising, considering that respondent had not been provided with the attorney he had already requested, despite having been subjected to police-initiated interrogation with respect to the first investigation as well. See n. 7, infra. We reiterate here, though, that the “right” to counsel to protect the Fifth Amendment right against self-incrimination is not absolute; that is, “[i]f authorities conclude that they will not provide counsel during a reasonable period of time in which investigation in the field is carried out, they may refrain from doing so without violating the person’s Fifth Amendment privilege so long as they do not question him during that time.” Miranda v. Arizona, 384 U. S. 436, 474 (1966).
  Indeed, the facts of this case indicate that different officers investigating the same offense are just as likely to bypass proper procedures as an officer investigating a different offense, inasmuch as the record discloses no less than five violations of the Edwards rule, four concerning the April 16 burglary and only one concerning the April 15 burglary. See Tr. 23-24, 49 (Apr. 3, 1986); Tr. 8-12 (Oct. 17, 1985, p.m.). It is only the last violation that is at issue in this case.
