Jefferson County Jail Overview
Jefferson County Jail is included in the Bonneville County facility map because an official ICE PREA audit identifies it as a nearby ICE contract jail in Rigby, about 15 miles north of Idaho Falls. It is not a Bonneville County jail, and it is not run by the Bonneville County Sheriff's Office. The facility is operated by the Jefferson County Sheriff's Office under an intergovernmental service agreement with DHS and ICE.
The ICE audit states that Jefferson County Jail housed adult male ICE detainees. It did not accept juvenile ICE detainees, female ICE detainees, or family units during the audit scope. The audit also says ICE detainees were housed in the same units as county inmates and separated by custody level based on prior jail experience and criminal history. That means the facility can have both regional county inmates and ICE detainees, but the search channel depends on the person's custody authority.
For a Bonneville County arrest that remains in local adult custody, use the Bonneville County Jail roster. For a person transferred to ICE custody, use ICE ODLS. For federal sentenced custody, use the BOP locator. For IDOC custody, use the state Resident/Client Search. Jefferson County Jail matters because immigration custody can move a person out of the local Bonneville roster path even when the arrest or family connection began near Idaho Falls.
Jefferson County Jail Capacity
The official ICE PREA audit listed Jefferson County Jail with a facility housing capacity of 135. During the January 24-26, 2023 audit, the report identified five ICE detainees. Those figures are audit-specific and should not be read as a current live count. The audit count also reflects ICE detainees, not the whole regional jail population at all times.
Because no current Jefferson County Jail daily population feed was found in the official sources, custody should be checked through the right authority. ICE ODLS covers current ICE custody and CBP custody longer than 48 hours. Local Jefferson County jail custody may require Jefferson County channels. Bonneville County Jail custody remains on the Bonneville sheriff roster only while the person is held there.
Jefferson County Jail ICE Lookup
The correct immigration custody lookup is the ICE Online Detainee Locator System. ICE says ODLS locates people currently in ICE custody or in CBP custody for more than 48 hours. The system does not search people under 18. An A-number search requires a nine-digit A-number and country of birth. A biographical search requires exact first name, exact last name, and country of birth, with optional birth date fields. ICE also lists the Detention Reporting and Information Line at 1-888-351-4024.
- Open ICE ODLS for immigration custody, or use the DRIL phone line when online search is not enough.
- Search by A-number and country of birth if the A-number is known.
- Use exact first name, exact last name, and country of birth for a biographical search.
- Confirm the facility name and custody status before planning a visit or sending mail.
Do not use the Bonneville County Jail roster for someone who has already been transferred to ICE custody unless the person is still physically listed in the Bonneville jail. ICE detainers can complicate release timing, but an ICE detainer is not the same thing as current ICE detention. ICE explains detainers as requests tied to custody transfer, including a 48-hour request period after local release authority.
Jefferson County Jail Contact
The facility map lists Jefferson County Jail at the courthouse complex in Rigby. The phone number below is the published jail contact. For ICE custody, ODLS or DRIL may be a better first step because the custody authority is federal immigration enforcement. For a local county inmate held by Jefferson County, the sheriff's office or jail should be contacted directly.

Regional county jail and ICE contract channel identified in official audit
Bonneville County readers should also keep location in mind. Rigby is outside Bonneville County, but it is close enough to Idaho Falls that regional custody transfers can create confusion. A person arrested in Bonneville County may first appear on the Bonneville roster, then disappear after release, transfer, state placement, federal transfer, or ICE custody movement.
Jefferson County Jail Visits
Jefferson County Jail is documented through the ICE PREA audit and facility map, not through a full official Jefferson County visitation page. For ICE detainees, visitation should be confirmed through ICE facility information and the jail before travel. Immigration detention visits may follow federal and facility rules that differ from ordinary county visitation.
| Visit Item | Source Status | Practical Use |
|---|---|---|
| ICE detainee visits | Confirm through ICE facility information and Jefferson County Jail | Use ODLS or ICE facility resources to confirm location first. |
| County inmate visits | Not detailed in the available official source | Call Jefferson County Jail for the current county-jail schedule. |
| Legal visits | May follow separate ICE or jail procedures | Confirm with the facility before travel. |
The Bonneville County Jail Telmate schedule does not apply to Jefferson County Jail unless Jefferson County independently publishes the same vendor and rules. Do not assume the visit type, fee, or schedule based on a different county facility.
Jefferson County Jail Mail
No official Jefferson County Jail mail, commissary, phone, or deposit fee table was found in the available Bonneville source set. For ICE detainees, mail rules often depend on ICE facility standards and the local jail contract facility. For county inmates, the Jefferson County Jail should be asked for its current address format, allowed items, rejected items, and money-deposit method. No fee table should be inferred from Bonneville County Jail or IDOC rules.
| Service | Provider / Detail |
|---|---|
| ICE custody lookup | ICE ODLS or DRIL at 1-888-351-4024. |
| Mail and phone | The official source did not publish a Jefferson-specific table. |
| Money deposits | No official fee table was published in the official source. |
Families should verify the person's exact custody status before sending funds. A person may be in local jail custody, ICE custody, federal pretrial custody, federal sentenced custody, or state custody, and each path has a different mail and money system.
Jefferson County Jail Intake
For the ICE channel, the key event is custody transfer or immigration detention, not a Bonneville County jail booking. ICE ODLS searches current ICE custody and CBP custody longer than 48 hours. The ICE detainer resource explains that a detainer asks a law-enforcement agency to notify ICE before release and to maintain custody briefly so ICE can assume custody. That process can be mistaken for a jail sentence, but it is a federal immigration custody action.
The ICE audit says adult male ICE detainees at Jefferson County Jail were housed in the same units as county inmates and separated by custody level. It also says the facility did not accept juvenile, female, or family-unit ICE detainees during that audit. Those facts should guide search expectations. If the person is under 18 or is a female ICE detainee, the audit does not support assuming placement at Jefferson County Jail.
About Jefferson County Jail
Jefferson County Jail is a regional facility in the Bonneville custody map because of its ICE connection near Bonneville County. It is not listed as a Bonneville County facility in the local adult jail system, and it is not the first place to search for a routine Idaho Falls arrest. Its value is as a nearby immigration custody channel, especially when a person is no longer visible on the Bonneville County Jail roster and family members suspect an ICE transfer.
Federal custody paths also differ. The BOP locator covers federal sentenced inmates from 1982 to present and shows public fields such as name, register number, age, race, sex, release date, and location. The U.S. Marshals Service handles federal pretrial custody in Idaho, but no public USMS inmate locator was found. ICE ODLS is the correct public immigration locator, and Jefferson County Jail is one of the nearby facility names to watch for in ICE custody results.
Note: Confirm ICE custody and facility placement before travel because transfers can change faster than public references update.
