Franklin County Inmate Population
Franklin County, Idaho does not publish a standard Franklin County jail roster or a local jail population dashboard in the official sources reviewed for this build. The official Franklin County Sheriff's Office page lists the sheriff's office at 39 West Oneida in Preston and links to VINELink and Caribou detention information. The official Franklin County District and Magistrate Court page adds detention-center and visitor-information links for Bannock County Detention Center, Cache County Jail, and Caribou County Detention Center. That local court page is the strongest Franklin source for how custody questions are routed.
The result is a Franklin County inmate population that may be counted in more than one place. A person arrested in Franklin County may be booked, transported, or housed by a contract jail. Cache County Jail, in Logan, Utah, states on its official corrections recruiting page that it houses Franklin County inmates along with Cache County, Utah State Prison, ICE, and U.S. Marshals Service inmates. Bannock and Caribou are also linked from Franklin County court or sheriff pages. Sentenced felony residents are not part of a county jail roster after transfer to Idaho Department of Correction jurisdiction.
Franklin County Inmate Population Data
Franklin County's own published facts page gives useful county context, but it does not provide a jail census, a rated local jail capacity, or annual booking totals. The county reports a 2020 Census population of 14,194, a land area of 667 square miles, and Preston as the county seat. Those figures describe the county community served by the sheriff and court system. They do not say how many people are in jail on a given day.
For jail-capacity facts, the researched sources point away from Franklin County and toward the housing facilities. Bannock County publishes a 330-inmate rated capacity for its detention center and describes its 1955, 1994, and double-bunking history. Cache County's own jail page does not publish a capacity figure in the captured text, but the research notes a Utah Department of Corrections jail directory figure of 374 total jail beds that should be checked against the original directory before relying on it as a final Cache capacity citation. Caribou's capacity was not found in official Caribou or Franklin sources.
| Measure | Figure | Source / Status |
|---|---|---|
| Franklin County population | 14,194 | Franklin County official facts page, 2020 Census |
| Franklin County jail capacity | Not located | No Franklin-run capacity page found |
| Franklin County jail current population | Not located | No Franklin roster or jail dashboard found |
| Bannock County Detention Center capacity | 330 inmates | Bannock County official jail page |
| Franklin-linked detention facilities | Cache, Bannock, Caribou, sheriff intake | Franklin court and sheriff pages |
Franklin County Jail Trends
No multi-year Franklin County jail average daily population table was located in the official sources. That absence matters. It means a Franklin County inmate population trend cannot be stated as a rising or falling local jail count without more source material, such as commissioner minutes, jail contracts, sheriff budget records, or a direct records response. The best supported trend is operational: Franklin County custody lookup is routed through the sheriff and outside detention facilities rather than through a local public roster.
The published facility context still helps readers avoid false assumptions. Bannock County says its current facility was built in 1994 for 264 inmates and was later double-bunked in several pods, bringing current rated capacity to 330. Cache County confirms that Franklin County inmates may be housed there. Those facts do not create a Franklin-only inmate population count, but they explain why a Franklin County inmate search can cross state and county lines.

| 2021 | Not published | Check contracts, minutes, or records requests for any jail-housing totals. |
| 2022 | Not published | No official Franklin jail dashboard found. |
| 2023 | Not published | Outside reports point to Cache housing in at least some Franklin cases. |

Who Counts as Franklin Inmates
The Franklin County inmate population can include several legal statuses. A recent arrestee may still be in sheriff custody while paperwork, transport, or court scheduling is underway. A pretrial detainee may be held at Cache County Jail, Bannock County Detention Center, Caribou County Detention Center, or another jail named by the sheriff or court. A person serving a short local sentence may also remain in jail custody. Once a felony sentence places the person under IDOC jurisdiction, the county jail search path usually no longer applies.
Federal and immigration custody are separate. Cache County states it houses ICE and U.S. Marshals Service inmates, but a Franklin County arrest does not by itself mean the person is in federal or immigration custody. A detainer is a hold from another agency. A detainer may keep someone in custody after local bond questions are resolved, so it should be checked with the jail that physically holds the person.
- Booking
- Jail intake after arrest, including identification, property, screening, and custody processing.
- Detainer
- A hold from another agency, such as IDOC, ICE, USMS, or another county.
- Pretrial
- Custody before the criminal case is resolved by dismissal, plea, trial, or sentencing.
- IDOC
- Idaho Department of Correction, the state system for sentenced felony residents, probation, and parole.
Franklin County Inmate Record Laws
Idaho law supports public access to many government records, but the right is not a promise that every jail record is online. Franklin County Court's records request form cites Idaho public-record law and requires a written request for court documents. Law-enforcement records may have exemptions, open-investigation limits, privacy limits, or agency policy rules. For Franklin County inmate records, the office holding the record matters as much as the statute.
Key access rules:
Idaho Code 9-338 is the public-record right-to-examine rule, subject to exemptions.
Idaho Code 9-339 controls public-record response timing and is cited by Franklin County Court's form.
Idaho Code 31-2202 describes sheriff duties, including jail and prisoner responsibilities.
Idaho Code 20-601 addresses county jails and lawful commitments.
For court records after a Franklin arrest, the court form asks for party names, case number when known, and specific document titles. It lists copy, certification, audio, and older-file research fees. It also says cases can be researched at the court public kiosk or through iCourt.
Start With Franklin Sheriff Custody
A recent Franklin County inmate search should start with the Franklin County Sheriff's Office when the housing location is unknown. The sheriff's page lists Sheriff Cuyler Stoker, phone 208-852-1234, fax 208-852-2580, and the office address at 39 West Oneida, Preston, ID 83263. The office is the local law-enforcement contact for arrest routing, transport questions, and whether a person has been placed in Cache, Bannock, Caribou, or another facility.
The Franklin County Sheriff's Office source page shows the local contact and detention resource links used for this custody path.
This is the local starting point, but it should not be read as a live Franklin County jail roster or proof that all Franklin inmates are housed in Preston.

Use for recent arrest routing and questions about which jail holds the person.
Search Franklin County Inmates
Because no Franklin County online jail roster was located, the best search method is a fallback chain. Have the person's full name, date of birth, arrest date, and the arresting agency or city if known. If one facility cannot confirm custody, ask whether the person was released, transferred, sent to court, or placed with another agency.
- Call Franklin County Sheriff's Office at 208-852-1234 for recent arrest routing and housing information.
- Call Cache County Jail at 435-755-1227 because Cache officially says it houses Franklin County inmates.
- Call Bannock County Detention Center at 208-236-7125 because Franklin County Court links Bannock detention information.
- Call Caribou County Sheriff's Office or Detention Center at 208-547-2561 because Franklin County pages link Caribou detention information.
- Check VINELink for custody notification, then use IDOC, BOP, or ICE locators if state, federal, or immigration custody is possible.
Note: A missing online roster result is not proof of release, especially where roster pages are unavailable or phone-only.
Franklin County Roster Search Limits
Franklin County does not have a captured roster search-field table because no official Franklin roster was found. Cache County's jail page describes current and last-30-day booking rosters, but both were unavailable in the captured text and labeled unofficial. Bannock's official jail page links a current jail inmate list, but the linked URL returned HTTP 404 on June 8, 2026. Caribou's detailed roster fields were not captured.
| System | Search Fields Found | Practical Use |
|---|---|---|
| Franklin County jail roster | No roster found | Call sheriff for housing path. |
| Cache County Jail | Unavailable roster sections | Call 435-755-1227 for booked-inmate information. |
| Bannock County Detention Center | Roster link found, but 404 during research | Call 208-236-7125. |
| IDOC Resident/Client Search | Last name, first name, IDOC number | Use for sentenced, probation, and parole status. |
| BOP Inmate Locator | Number or name, with optional race, age, sex | Use for federal custody from 1982 to present. |
Franklin County Detention Facilities
Franklin County inmate population questions may involve four linked custody paths. The primary local contact is not a stand-alone rostered jail in the researched sources. It is the sheriff's office and contract-placement path. The other facilities are where day-to-day jail rules, visitation, mail, money, and booking information may be controlled.
- Franklin County Sheriff's Office / Contract Jail Placement handles local sheriff intake, routing, and contract-placement questions for Franklin County arrests.
- Cache County Jail is an official Franklin housing path; Cache says it houses Franklin County inmates along with ICE, USMS, Utah State Prison, and Cache County inmates.
- Bannock County Detention Center is linked from Franklin County Court and publishes a 330-inmate rated capacity, detention phone, VINE, Securus, and Access Corrections information.
- Caribou County Detention Center is linked by Franklin County sheriff and court pages, but its detailed roster and visit rules were not captured in official sources.
Cache and Bannock Custody
Cache County is important because it directly names Franklin County as one of the inmate sources housed at its jail. Its official jail page also warns that current and recent booking lists are informational, unofficial, and currently unavailable in the captured text. It tells users to call 435-755-1227 for booked-inmate information. The current list also excludes Utah State or Federal inmates housed at Cache, so one visible list would not cover every person in that building even when available.
The Cache County Sheriff's Office careers page is the source that names Franklin County among jail population sources.
That official Cache statement is why Logan, Utah, can be relevant to a Franklin County inmate population search even though Franklin County is in Idaho.
Bannock County Detention Center is also linked from Franklin County's court detention resources. Bannock publishes a 330-inmate capacity, phone number 208-236-7125, VINE link, Securus visitation account path, Access Corrections deposits, and bond-posting instructions. Its current roster link could not be inspected because the URL returned 404 during research, so Bannock custody should be checked by phone if the roster is not working.
State Federal ICE Lookup
County jail custody, state prison custody, and federal custody are separate systems. The Franklin County inmate population search starts with the sheriff or housing jail for recent arrests and local court commitments. If a person is sentenced to Idaho Department of Correction custody, use the IDOC Resident/Client Search. IDOC covers people on court probation or currently under IDOC jurisdiction, including incarcerated, probation, and parole statuses.
Federal custody uses the BOP Inmate Locator, which covers federal inmates from 1982 to the present and shows fields such as name, register number, age, race, sex, release date, and location. Immigration custody uses ICE ODLS. VINELink is a notification path rather than a complete roster, but Franklin and Bannock both link to VINE.
| Custody Type | Where to Look | What It Covers |
|---|---|---|
| Recent Franklin arrest | Franklin sheriff, then Cache/Bannock/Caribou | Local routing and current jail custody. |
| Sentenced Idaho felony resident | IDOC Resident/Client Search | Incarceration, probation, and parole under IDOC. |
| Federal prisoner | BOP Inmate Locator | Federal custody from 1982 to present. |
| Immigration detainee | ICE ODLS | Immigration detention, subject to ICE search limits. |
Franklin County Records Requests
Past or released Franklin County inmate records may require a records request because no Franklin jail archive was found online. Start by identifying the agency that holds the record. Court documents are handled through Franklin County Court. Booking, transport, or law-enforcement records may start with the sheriff or the jail that physically housed the person. If Cache, Bannock, or Caribou created the booking record, Franklin County may not be the office with the full jail file.
Franklin County Court's March 2024 public-records form requires the parties, case number if known, and specific document titles. It lists $1.00 per page for copies, $2.00 per certified document, $12.00 for an audio recording on flash drive, and a $20 nonrefundable research fee for files prior to October 1, 2018. The form says response may take up to three business days, or up to ten business days with written notice under Idaho Code 9-339.
Visits Mail and Money
Visitation, mail, and inmate funds depend on the housing jail. Franklin County did not publish a local jail visitation calendar, commissary vendor, or inmate mail rule page in the sources reviewed. Cache County Jail uses NCIC video visitation and gives on-site visit windows. Bannock County points visitors to Securus for visits and Access Corrections for deposits. Caribou details were not captured in official sources, so phone verification is needed before travel or deposits.
| Facility | Visit or Money Details Found | Phone |
|---|---|---|
| Cache County Jail | NCIC visits; two free on-site visits weekly; JailATM money; CBM commissary. | 435-755-1227 |
| Bannock County Detention Center | Securus visits; Access Corrections deposits; bond at sheriff's office. | 208-236-7125 |
| Caribou County Detention Center | Detailed official schedule not captured. | 208-547-2561 |
Franklin County Inmate FAQ
Is there a Franklin County jail roster? No official Franklin County online jail roster was located in the researched sources. The sheriff and court pages instead point users to detention information for outside facilities, especially Cache, Bannock, and Caribou.
How big is the Franklin County inmate population? A single Franklin jail ADP or current count was not published in the located sources. The most accurate answer is that Franklin County custody is distributed through contract or linked facilities, with sentenced felony residents searched through IDOC.
Can VINELink replace calling the jail? VINELink can help with custody notifications, but it is not the same as a complete jail records file. Use it with the sheriff, housing jail, court records, and state or federal locators.
Are Franklin County mugshots online? No Franklin mugshot gallery was found. Cache County says booking photos are no longer available to download, and Bannock's roster link could not be inspected during research.
Where do court charges appear? Filed charges appear through Franklin County Court records and Idaho iCourt after the prosecutor files or approves the case. Booking charges and filed court charges may differ.
