Grand Prairie and the DSCC at a glance
Grand Prairie, Texas, is where the Bureau of Prisons decides, in most cases, which prison a newly sentenced person goes to, and where it computes the release date. The Designation and Sentence Computation Center (DSCC) does that work. It is one of three offices in the Bureau’s Grand Prairie Office Complex, holds nobody, and sits under the Central Office rather than a region.

What is the Grand Prairie Office Complex?
The Bureau’s Offices page, read September 18, 2026, says the complex “was created to better serve employees and consolidate various processes to achieve more streamlined, efficient, and cost-effective Bureau-wide operations,” and that its staff have “expertise in human resources; inmate classification, designations, and sentence calculation; and financial management.” The Human Resource Services Center and the Field Acquisition Office serve the Bureau’s own staff and purchasing; only the DSCC deals with people in custody.
The Bureau’s records give the complex the same street address as the South Central Regional Office. They are different offices: the region oversees prisons such as those on our Texas page, while the DSCC works for every institution in the country.
Program Statement 5100.08 (Sept. 12, 2006) records “the movement of most designation/redesignation functions (04-08-17) to the Designation and Sentence Computation Center (DSCC), Grand Prairie, Texas” (at p. 7).
What does the Designation and Sentence Computation Center do?
Program Statement 5800.15, the Correctional Systems Manual (Jan. 1, 2009), lists its job at p. 13: “Ensuring placement of inmates in facilities commensurate with their security and program needs”; “Computation of various types of sentences in order to establish an inmate’s statutory release date”; “Auditing sentence computations”; and “Monitoring the status of contract prisoners.” The manual succeeded the Inmate Systems Management Manual. At p. 14 its staff are “Section Chiefs, attorneys, supervisory staff, classification, computation and designation staff.”
Two other decisions sit with its lawyers. Under PS 5331.02 (as amended May 7, 2026) at p. 1, DSCC legal staff review a person’s offenses to decide whether completing RDAP can shorten the sentence, and “will ordinarily have 30 working days” to do it. And under PS 5160.06 at p. 3, “The DSCC Sentence Computation Section Chief is delegated the Bureau’s authority to designate a state institution for concurrent service of a federal sentence.”
How does a designation request reach the DSCC?
Through the Marshals, not the family. PS 5100.08 at p. 23 sets out the chronology: the person is sentenced; the clerk sends the judgment to the U.S. Marshals Service; and “The USMS makes a request to the DSCC advising that the inmate is now ready for designation to a facility.” The DSCC then collects the presentence report, the judgment with its statement of reasons, and the Marshals’ custody report.
The same page sets the pace: the DSCC “will ordinarily complete the initial designation within three working days of receiving all the necessary documentation.” Cases with medical or mental-health concerns go to the Office of Medical Designations and Transfers in Washington. For the rest, a designator scores the file in SENTRY and picks an institution (at pp. 14–15), and “will make every effort to accommodate recommendations from the courts, ie. RDAP, locality, etc.” (at p. 26).
The statute frames that choice. Under 18 U.S.C. § 3621(b), the Bureau places a prisoner “in a facility as close as practicable to the prisoner’s primary residence, and to the extent practicable, in a facility within 500 driving miles of that residence,” subject to bed space, security, program and health needs and the court’s recommendation. The same subsection ends: “Notwithstanding any other provision of law, a designation of a place of imprisonment under this subsection is not reviewable by any court.” See our pages on designation, security levels and the classification policy.
How does the DSCC compute a federal sentence?
From two statutory dates. A sentence “commences on the date the defendant is received in custody awaiting transportation to, or arrives voluntarily to commence service of sentence at, the official detention facility at which the sentence is to be served.” 18 U.S.C. § 3585(a). Jail time before that counts under § 3585(b) only if it “has not been credited against another sentence.”
The judge does not do that arithmetic. “After a district court sentences a federal offender, the Attorney General, through BOP, has the responsibility for administering the sentence.” United States v. Wilson, 503 U.S. 329, 335 (1992). PS 5800.15 at p. 32 requires a computation to be done and audited “immediately” within 30 days of release, within five working days inside six months, and otherwise within 30 calendar days.
State time is the hard case. When someone owes both a state and a federal sentence, the Bureau treats a request for federal credit for state time as a request for a nunc pro tunc designation of the state prison (PS 5160.06 at p. 6). Where such a designation may be appropriate, the Section Chief writes to the federal sentencing court and, if no answer comes “after at least 60 days,” decides on the § 3621(b) factors (at p. 7). The Supreme Court has held that a federal judge may order the sentence to run consecutively to a state sentence not yet imposed. Setser v. United States, 566 U.S. 231 (2012). See our nunc pro tunc page and the Sentence Computation Manual.
What can a defense lawyer or family do?
Most of the leverage comes before the DSCC opens the file. The designator works from the presentence report and the judgment, so an error left in the report travels into the security score, and a recommendation the judge never wrote cannot be weighed. PS 5100.08 at p. 23 notes that the statement of reasons “may contain information which overrides the PSR and may affect scoring decisions.”
After sentencing, a family cannot learn the destination early. PS 5100.08 at p. 28: release of designation information “is prohibited, for security reasons, until the inmate has arrived at the designated facility.” A scoring mistake found later is raised through the institution’s case management coordinator, who contacts the DSCC, with disagreements settled by the Central Office (at p. 27).
A computation dispute goes through the administrative remedy process, and PS 1330.18 at pp. 8–9 names “sentence computation” among the issues for which consideration “should be given to accepting a Request or Appeal” even when “somewhat untimely.” Family and lawyers can help draft, but PS 1330.18 at p. 8 is plain that “no person may submit a Request or Appeal on the inmate’s behalf.” Our page on challenging a computation covers what follows.
How do I contact the DSCC?
Use the DSCC’s own lines, which the Bureau’s Grand Prairie page listed on September 18, 2026: telephone 972-352-4400 or 972-352-4499, fax 972-352-4395, and the mailbox BOP-CPD-DSC-PolicyCorrespondence-S@bop.gov. The complex’s main number, 972-352-4500, is the one that page gives the Field Acquisition Office, a purchasing office, so it is the wrong call for a designation or computation question. Staff mail goes to a named person, “Designation & Sentence Computation Center,” at the staff-mail address.
Nothing for a person in custody belongs here. The DSCC holds nobody, so a letter sent there for a prisoner is misdirected; see writing to someone in federal prison.
Frequently Asked Questions
How long does an initial designation take?
Program Statement 5100.08 says the DSCC will ordinarily complete an initial designation within three working days of receiving all the documents it needs from the Marshals and the probation office. The clock starts only once the presentence report and judgment are in hand.
Does a judge’s recommendation decide the prison?
No. The recommendation is one factor the Bureau must consider under 18 U.S.C. § 3621(b), and Program Statement 5100.08 says designators make every effort to accommodate it. The final choice is the Bureau’s, and the statute says a designation under that subsection is not reviewable by any court.
Can I find out where my relative has been designated before they arrive?
Ordinarily not. Program Statement 5100.08 prohibits release of designation information to the public, for security reasons, until the person has arrived at the designated facility. The person may be told the destination but not the date. Once they arrive, the institution appears in the Bureau’s inmate locator.
Who fixes an error in jail credit?
The Bureau computes the credit, not the sentencing judge; the Supreme Court said so in United States v. Wilson. A mistake is raised informally with staff first and then through the administrative remedy process, where Program Statement 1330.18 lists sentence computation among issues to accept even when somewhat late.
Is the DSCC the same as the South Central Regional Office?
No. Both sit in the U.S. Armed Forces Reserve Complex in Grand Prairie, but the regional office oversees the prisons of the South Central Region and decides BP-10 appeals from them. The DSCC designates and computes sentences for people across the country, and the roster files it under the Central Office.
What is a nunc pro tunc designation?
A designation of a state prison, after the fact, as the place a federal sentence was served, so that state time counts toward it. Under Program Statement 5160.06, the DSCC Sentence Computation Section Chief decides these, ordinarily after writing to the federal sentencing court and waiting at least 60 days for an answer.
Where we can help
The files we see from Grand Prairie are a designation far from home or at the wrong security level, a release date that ignores jail credit, and state and federal sentences that should have overlapped and did not. Some of it is court work under § 2241.
