The Collin County Detention Facility’s direct phone number is (972) 547-5200. The Sheriff’s Office main administrative line is (972) 547-5100. Neither number will connect you to someone in custody, because inmates at the Collin County Jail cannot receive incoming calls. Every call from the facility is outgoing, placed by the inmate through the jail’s contracted phone provider, so reaching a person inside means setting up an account on your end and waiting for them to call you.
Which Number to Call for What
The detention facility is located at 4300 Community Avenue in McKinney, Texas. Staff on the (972) 547-5200 line can answer questions about housing assignments, bond amounts, and booking status. The (972) 547-5100 line handles Sheriff’s Office matters beyond the jail itself. Staff on either line will not transfer you to an inmate and will not pass along messages.
Finding the Inmate First
Before setting up a phone account, confirm the person is in custody and get their identification number. Collin County runs a Judicial Online Search portal through its Case Information page at collincountytx.gov.1Collin County. Case Information Searching by name pulls up the inmate ID, current bond amount, booking photo, and time-served record. You’ll need that ID when you fund a phone or commissary account.
How Calls From the Jail Actually Work
The Collin County Sheriff’s Office contracts with ViaPath Technologies and ICSolutions for inmate telephone and communication services.2Collin County. Inmate Information: Visitation and Phones Inmates place calls from phones in their housing area. The call reaches you as either collect or prepaid, depending on how your account is configured. Each call opens with an automated recording identifying the facility and the caller, and you’ll be prompted to accept charges before the line connects.
Any phone that can accept collect or prepaid calls will work. Standard cell phones and landlines are generally fine. Some VoIP and app-based services don’t route these calls properly, and when a call fails, the problem is almost always on the receiving side rather than at the jail.
Setting Up a Prepaid Account
A prepaid account through the provider lets the inmate reach you without you accepting collect charges each time. Select the Collin County Detention Facility during signup, enter your phone number, and fund the balance. Calls draw from the balance automatically. Funding typically caps at $100.00 per transaction, paid by credit card or electronic check.
When Calls Aren’t Getting Through
Blocked numbers are the most common cause. Carriers sometimes flag inmate calls as spam, and a previous unpaid collect balance can trigger an automatic block. If expected calls aren’t coming through, contact the provider’s support line. For general Securus-managed facilities, mobile support is 972-734-1111 and the landline number is 1-800-844-6591.3Securus Technologies. Contact Us For Collin County specifically, check the visitation and phones page on the county website for current provider contact information, since the contract is with ViaPath Technologies and ICSolutions.2Collin County.

What You Can and Can’t Do on the Call
Every call is recorded and monitored. The only exception is a call between an inmate and their attorney of record, and that protection depends on the lawyer’s number being properly registered with the jail. An automated notice confirms the recording at the start of each call. Recorded conversations are routinely used as evidence, so treat everything said on the line accordingly.
Calls have a set time limit and the system disconnects automatically when it expires. A cooldown period usually follows so one person doesn’t tie up a housing unit’s phone. Attempting a three-way call, forwarding the call to another line, or handing the receiver to a different person on the outside will drop the call immediately, and the inmate can lose phone privileges for an extended period afterward.
What Calls Will Cost Starting April 2026
The Martha Wright-Reed Just and Reasonable Communications Act gave the FCC authority to cap what providers charge for calls from jails and prisons. New rate caps take effect April 6, 2026, and apply to all audio and video calls regardless of whether the call crosses state lines.4Federal Communications Commission. Incarcerated People’s Communications Services
Collin County’s detention facility had an average daily population above 1,100 in fiscal year 2024, placing it in the large-jail tier: $0.10 per minute for audio calls and $0.19 per minute for video.4Federal Communications Commission. Incarcerated People’s Communications Services The FCC also prohibited ancillary charges like automated payment fees and third-party transaction fees, so the per-minute rate should track closely to your actual cost.5Federal Register.

Keeping the Phone Account Funded
The phone account and an inmate’s commissary account are separate systems, funded through different vendors. If your prepaid phone balance runs out, an inmate with phone access still won’t be able to reach you until you top it up. Check the balance regularly if you’re expecting calls, and confirm the provider hasn’t flagged your number after any billing gap.
