This page helps you use official Collin County, Texas inmate search tools to check whether someone is in jail, review basic custody details, and move to the right county resource for bonds, visitation, mail, or case follow-up.

The main starting points are Judicial Online Search and the Sheriff’s Office inmate information pages. This site is independent and does not provide legal advice or guarantees.

Collin County inmate lookup

Start with the county’s online inmate list. It covers current inmates and people released within the past 24 hours.

  • Search the official inmate lookup.
  • Browse the list or search for the person you need.
  • Open the matching record to review details such as arrest date, release date, days confined, SO number, housing information, and charges.
  • Use the linked court information on the record when you need to follow the case beyond the jail listing.

The county’s broader inmate information page also points users to the jail list and related jail services for people already in custody.

A matching record may also show items such as mug shots, bond amounts, and time served when those details are available in the county’s online system.

Case and court follow-up

If you need more than the custody record, the county’s court tools can help you move from the inmate listing to case details and court schedules.

  • Justice System App Online Judicial Search can connect inmate results to criminal cases.
  • Case Search covers many active and historical case types, but its case data updates daily at 6 p.m.
  • Case Record Inquiry can be useful when you need court-side changes reflected in real time.

For a wider set of case and calendar tools, review the county’s case information options.

Some older records are not available through the online search tools and require a manual case record search through the appropriate clerk’s office.

Bond and release options

After you confirm someone is in custody, the next step may be bond or release review.

  • Cash or surety bonds are accepted at 4300 Community Ave., McKinney, TX 75071.
  • Bonds can be posted at any time because the Sheriff’s Office is open 24/7 for bonds.
  • Cash bonds may be paid in cash, money order, or cashier’s check payable to Collin County Sheriff’s Office.
  • Pretrial release bonds require approval by a judge and carry a non-refundable fee of 3% of the bond amount or $20.00, whichever is higher.

For the county’s bond process and related jail guidance, check the inmate bond information.

Visits, calls, and deposits

Once you find the person you need, the next questions are often how to visit, how calls work, and how to add money to an account.

  • Inmates at the Collin County Detention Facility can make pre-paid account calls only.
  • All visitors must arrive 20 minutes before scheduled visitation time.
  • Visits last 25 minutes, with 5 additional minutes added for walking time to the cluster.
  • Only one adult visitor per inmate is allowed each visitation day, and the visitor must be on the inmate’s visitation list.
  • Money for commissary and other inmate account uses goes through the county’s approved deposit options rather than cash, checks, or money orders by mail.

Visitation times can change without notice, and late visitors are not permitted to go to visitation.

Mail and property rules

Mail and property follow separate jail rules, so it helps to check them before you send anything or try to pick up belongings.

  • Personal mail must be sent to Collin County Detention Facility, inmate’s full name, inmate SO number, P.O. BOX 247, Phoenix, MD 21131.
  • Legal mail and publications from a publisher, distributor, or authorized retailer should be sent to Collin County Detention Facility, 4300 Community Ave., McKinney, TX 75071.
  • The front desk does not accept personal mail in person.
  • Bulk property may be released one time while the inmate is in custody, between 6:00 a.m. and 9:00 a.m. daily, on an all-or-nothing basis.
  • Valuable property may be released on an all-or-nothing basis at any time.

Personal mail sent directly to the facility is returned to the sender, and the jail does not accept checks or money orders through personal mail.

Common questions

Does the online list show only current inmates?

No. The Sheriff’s Office says the jail list includes current inmates and people released within the past 24 hours. If you do not see someone right away, check the jail list again and then review linked case information if needed.

Can I see court information after I find an inmate?

Yes. The county’s online judicial tools can connect inmate results to criminal case information. If you need broader case or calendar access, use the county’s case information page and choose the tool that matches your need.

Some historical records require a manual case record search. That includes older criminal cases in District Courts from 1800 through 1987, older criminal cases in County Court at Law from 1800 through 1999, and some older civil, probate, and Justice Court records. When that happens, contact the appropriate clerk’s office for a manual lookup.

Can I call or leave a message for an inmate?

The jail does not accept messages for inmates, and inmates cannot receive incoming calls. Calls work through pre-paid phone accounts, and inmates can also buy phone time from commissary funds. If you are trying to stay in contact, set up the phone option first and then review visitation rules.

Where do I post a bond for someone in the Collin County jail?

Bonds are accepted at 4300 Community Ave., McKinney, TX 75071. The Sheriff’s Office states that bonds can be posted 24/7, and cash or surety bonds are accepted. If you are planning a cash bond, confirm the payment form before you go.
