St. Clair County, Michigan Custody Guide 2026
Find St. Clair County Jail Inmates, Booking Records and Custody Status
Use the official St. Clair County Sheriff inmate lookup to check whether someone is currently held at the Intervention & Detention Center in Port Huron. Search by last name, first name or booking number, then use the jail, court or Michigan Department of Corrections system according to what happens next.
This guide also explains what to do when the person does not appear, how to verify bond and court information, schedule a visit, fund commissary, send mail under the new 2026 mailing rules and distinguish a county-jail booking from an MDOC prison or supervision record.

Which St. Clair County Search Should You Use?
Someone arrested or currently in county custody
Start with the official St. Clair County Sheriff Inmate Lookup. It searches current booking records held by the Sheriff’s Office.
Someone transferred to state prison or MDOC supervision
Use Michigan OTIS for eligible offenders who are or were under Michigan Department of Corrections jurisdiction or supervision.
Need the criminal court case
Search the St. Clair County court system. A jail record confirms custody; the court file controls hearings, charges, case status and judicial orders.
Do not treat “not found” as proof of release: the person may be in booking, transferred, housed elsewhere, released before the latest update, held under a different spelling or moved into state custody.
Start Here: Choose What You Need to Know
Is the person in jail now?
Search the Sheriff’s current-custody database by name or booking number.
Need the correct booking?
Match the full name, booking identifier and available custody information before taking another action.
Need bond information?
Confirm the amount and court first. Bond payment location changes depending on whether the court is open.
Want to visit or receive calls?
Create an InmateSales account and schedule qualifying visits at least 24 hours ahead.
Want to send money or mail?
Use TouchPay for inmate funds and the correct 2026 mail address for non-legal correspondence.
Need an arrest or police report?
Contact the Sheriff’s Service Bureau or submit a written FOIA request.
How to Use the Official St. Clair County Inmate Lookup
The Sheriff’s dedicated inmate portal searches people currently in custody. It accepts a last name, first name or booking number, and the county states that a search can begin with as little as one letter.
Start with the last name.
Enter the surname only. This is often safer than entering a full name when you are unsure about middle names, initials or spelling.
Broaden the search when needed.
The official portal allows a single-letter search. For example, entering the first letter of a surname can reveal current bookings beginning with that letter.
Add the first name to narrow results.
Use this when several people have the same surname.
Use the booking number for a precise lookup.
If you received a booking number from the jail, court, arrest paperwork or family member, enter it directly instead of relying on name matching.
Open the matching custody record.
Compare all available identifiers instead of assuming the first name match is the correct person.
Check the portal’s refresh notice.
The inmate site displays when its data was last refreshed and states that information is updated periodically throughout the day.
Verify time-sensitive details before paying or traveling.
Bond, release, transfer and court status can change after the online record updates.
Best search order: booking number → exact surname → surname + first name → first letter of surname.
Search Problems That Commonly Hide a Current Booking
| Problem |
Try This |
Why It Helps |
| Full name returns nothing |
Search only the surname. |
Middle names, hyphens or alternate spellings can narrow the search too much. |
| Unsure of spelling |
Search the first letter or first few letters. |
The official lookup supports partial searching. |
| Several people appear |
Add the first name and compare booking information. |
Never rely on surname alone when multiple current records match. |
| Arrest happened very recently |
Check again later or call the jail. |
Booking and public-data updates are not necessarily instantaneous. |
| Person was there yesterday |
Check court records and MDOC OTIS. |
The person may have been released, transferred or moved into another custody system. |
| You only know an alias |
Search known legal names and name variations separately. |
The custody record may not be indexed under the nickname you know. |
Verify the Person Before Paying Bond or Sending Money
Full name
Match spelling.
Booking number
Copy it exactly.
Custody status
Confirm still held.
Court
Identify the case court.
Bond
Verify live amount.
Inmate ID
Needed for deposits/mail.
Money-transfer warning: TouchPay requires the inmate name, inmate ID and St. Clair County site ID. Confirm the correct inmate before submitting funds because two people can have similar names.
What Happens After a St. Clair County Arrest?
Arrest / Intake
Identity and booking information are processed.
Current Jail Record
Eligible current custody appears in the Sheriff lookup.
Arraignment / Court
Court orders control charges, bond and future hearings.
Release or Sentence
The person may bond out, be released, serve county time or receive another disposition.
Transfer / MDOC
Some sentenced people later appear in Michigan OTIS instead of the county jail lookup.
72-hour classification: the Sheriff states that inmates confined for more than 72 hours are generally classified and assigned to general population, subject to exceptions required by conditions or security.
If the Person Is Not Listed in the St. Clair County Jail Search
Check the spelling
Search only the surname, then use fewer letters. Do not rely on a nickname.
Consider booking delay
A very recent arrest may not be visible in the public portal immediately.
Check state custody
Use
Michigan OTIS when a transfer to MDOC custody or supervision is possible.
Check the court case
A court file can show proceedings even when the person is no longer in the county jail.
Call the jail
General inquiries:
810-987-1700. For bond or substantiated emergency inmate-contact questions, use
810-987-1720.
Do not assume release time
Court orders, holds, processing and transportation can affect when physical release actually occurs.
How Bond Works at St. Clair County Jail
The correct payment location depends on whether the court is open.
During regular county court business hours
The Sheriff instructs that bond must be paid at the court. Confirm the correct court and case before traveling.
When the court is closed
The jail accepts cash bonds and credit cards, subject to the Sheriff’s rules. Licensed bonding agents are treated differently.
Verify the inmate is still in custody.
Search the current inmate portal immediately before arranging payment.
Identify the court and case.
Do not rely only on verbal bond information from a third party.
Confirm the current bond amount.
Call
810-987-1720 when jail bond information needs confirmation.
Determine where payment must be made.
Court-open and court-closed procedures are different.
For authorized credit-card payment, follow the official route.
The jail lists
GovPayNow and telephone number
1-888-604-7888.
Keep the payment confirmation.
Save the receipt and case information until release is confirmed.
Release is not always immediate after payment: jail processing, court paperwork, holds or another jurisdiction can affect the actual release time.
