Short answer

The Bureau of Prisons designates the place of imprisonment under 18 U.S.C. section 3621(b), subject to bed availability, the person's security designation, programmatic needs, mental and medical health needs, faith-based requests, recommendations of the sentencing court and other security concerns, placing people as close as practicable to their primary residence and, to the extent practicable, within 500 driving miles. Classification and designation functions are centralized at the Designation and Sentence Computation Center. CaseSteps never predicts a facility.

Attorney review pending. This is general education, not legal advice.

Plain-English overview

The direct answer: the Bureau of Prisons decides. Under 18 U.S.C. § 3621(b) the Bureau designates the place of imprisonment, and its classification and designation functions are centralized at the Designation and Sentence Computation Center at the Grand Prairie Office Complex in Texas.

The statute directs the Bureau, subject to bed availability, the person's security designation, programmatic needs, mental and medical health needs, any faith-based request, recommendations of the sentencing court and other security concerns of the Bureau, to place the person in a facility as close as practicable to their primary residence, and to the extent practicable within 500 driving miles of it.

Designation is not transportation. A designation decision says where; it does not say when a person will physically arrive, and CaseSteps gives no timing of any kind.

Why this matters

Families often treat the judge's words at sentencing as the placement decision, and then treat any other outcome as a mistake. The authority is statutory and it sits with the Bureau.

The major considerations, without predicting any placement

  • The level of security and staff supervision the person requires.
  • The level of security and staff supervision the institution provides.
  • The person's medical care level and the care level of the institution.
  • Mental-health care needs.
  • Program needs, such as substance-abuse treatment, education and vocational training, or counseling.
  • Bed-space capacity and population concerns.
  • Release residence and the 'as close as practicable' standard, including the 500-driving-mile provision.
  • Recommendations of the sentencing court.
  • Separation needs and other security or operational concerns, including protection of victims, witnesses and the public.

Ten things people treat as one thing

Sentence commencement

The date a federal term of imprisonment begins under 18 U.S.C. § 3585(a).

Prior-custody credit

Credit under § 3585(b) for time in official detention before the sentence commenced, computed by the Bureau of Prisons.

Good-conduct time

Up to 54 days per year of the sentence imposed under § 3624(b), based on the Bureau's determination about institutional conduct.

First Step Act Time Credits

A separate credit earned by eligible people for successfully completing assigned qualifying programming, with its own earning and application rules.

A projected release date

A forward-looking figure produced by the Bureau's computation that changes as records change.

A conditional or projected prerelease date

A different figure about community placement, not the end of the term of imprisonment.

Designation

The Bureau's decision under § 3621(b) about which facility a person is assigned to.

Transportation

The physical movement to that facility, which happens separately and on no published timetable.

Federal custody, state custody, primary jurisdiction

Which sovereign holds primary custodial jurisdiction is a separate question from who is physically holding someone on a given day.

A court recommendation and the BOP's authority

A sentencing court may recommend a facility or program; § 3621(b) leaves the designation decision with the Bureau of Prisons.

How the process is described in official material

Before a designation is made, the Designation and Sentence Computation Center must receive all sentencing material for consideration. Those documents come from the sentencing court, the United States Probation Office and the United States Marshals Service.

Program Statement 5100.08 states that the Center will ordinarily complete the initial designation within three working days of receiving all the necessary documentation, which it identifies as the presentence report, the judgment, the statement of reasons and Central Inmate Monitoring documentation where applicable.

That three-working-day statement is about the designation decision only. It is not a promise that any documentation arrives on any schedule, and it is not a promise that physical transportation will occur within three days or within any other period. CaseSteps will not estimate how long anything takes.

The same criteria apply to initial designation and to a later redesignation for transfer. Requests for transfer originate with the unit team at the person's current facility.

Common misunderstandings

  • "Three working days means transfer in three days." It does not. The statement is about completing the initial designation once all necessary documentation has been received.
  • "Designation means a bus is coming." Designation and transportation are separate steps.
  • "Everyone goes within 500 miles of home." The statute uses 'as close as practicable' and 'to the extent practicable,' subject to the listed factors. The Bureau states that placement beyond 500 driving miles is generally due to specific security, programming or population concerns.
  • "Someone will be told the transfer date." The Bureau states that designation and transfer information is withheld for security reasons until arrival, and that a person confined in a Bureau facility may be advised of the destination but not of the date or time of transfer.

Records that may help clarify the issue

  • The judgment and commitment order, including any judicial recommendation.
  • The statement of reasons.
  • The presentence report as it affects classification and program needs.
  • Medical and mental-health records relevant to care level.
  • Any Central Inmate Monitoring or separation information in the file.
  • Do not upload any of these records to CaseSteps, and do not type case numbers, dates or names anywhere on this site. Nothing here accepts files or keeps what you type.

Questions for appropriate Bureau of Prisons staff

  • In general terms, what stage is the designation process at?
  • Which documents does the Designation and Sentence Computation Center still need?
  • How are program or medical needs raised for consideration?
  • How does a person request that the unit team consider a transfer closer to a release residence later on?

Exactly where each statement above comes from — source checked: September 6, 2026

  • Designation authority and the listed factors, including bed availability, security designation, programmatic needs, mental and medical health needs, faith-based requests, court recommendations, other security concerns, 'as close as practicable' and 500 driving miles: 18 U.S.C. § 3621(b), official U.S. Code text on GovInfo, read September 6, 2026.
  • Centralization at the Designation and Sentence Computation Center, the documents required before designation, the security/programming/population explanation for placement beyond 500 driving miles, and the criteria list applying equally to designation and redesignation: Bureau of Prisons Designations page, read September 6, 2026.
  • 'The Designation and Sentence Computation Center will ordinarily complete the initial designation within three working days of receiving all the necessary documentation' from the United States Marshals Service and the United States Probation Officer — presentence report, judgment, statement of reasons and Central Inmate Monitoring documentation: Program Statement 5100.08, Chapter 3, page 1, read September 6, 2026 in the version carrying Change Notice CN-3 dated May 6, 2026.
  • Non-disclosure of transfer dates: Bureau of Prisons Designations page, and Program Statement 5100.08, Chapter 3, page 6.
  • Change Notice CN-3 (May 6, 2026) updates Section 1 of Program Statement 5100.08 and states that classification, designation and redesignation procedures are consistent with the statutory authority in 18 U.S.C. § 3621(b).

What CaseSteps cannot do

CaseSteps does not calculate prior-custody credit, good-conduct time, First Step Act Time Credits, a release date or any other figure.

CaseSteps does not predict a facility, a designation, a transfer date, a transportation route or how long anyone will remain in a detention facility, and it does not say whether sentences run concurrently or consecutively in a particular case or whether a detainer is valid.

The Bureau of Prisons performs the official sentence computation and holds the designation authority. Individual questions belong with appropriate Bureau staff and with qualified counsel.

Questions to discuss with counsel

  • In general terms, which considerations under § 3621(b) are most relevant to my situation?
  • Is there anything in the record that counsel should address before designation material is complete?
  • How does a judicial recommendation get communicated to the Bureau of Prisons?
  • What is the general process if a designation appears inconsistent with documented medical needs?
  • Which questions here belong with the Bureau of Prisons rather than with the court?

This is general federal legal education, not legal advice. Procedures and outcomes depend on the facts, the controlling law, court orders and local practices. Confirm deadlines and decisions with qualified counsel.
