California State Prison, Los Angeles County (LAC – Lancaster): How to find Inmate Information, Contact Inmates and More

California State Prison, Los Angeles County, commonly called LAC or Lancaster, is a state-run men’s prison operated by the California Department of Corrections and Rehabilitation (CDCR).

LAC is in Lancaster in the Antelope Valley. Confirm the current housing assignment through CIRIS; the prison’s name does not mean a person is held in the Los Angeles County jail system.

The address for LAC is:

California State Prison, Los Angeles County
44750 60th Street West
Lancaster, CA 93536
(661) 729-2000

Driving directions: Google Maps

LAC includes several yards with different security levels, from minimum- to maximum-security housing. It is not a county jail and does not house people awaiting bail hearings.

Most men held here have been convicted in state court and are serving their sentences.

How bail works for LAC

Ordinary pretrial bail is not posted at a CDCR prison to release someone serving a state sentence. Any exceptional release pending appeal or postconviction order must be addressed in court; it is a different process from posting county-jail bail.

If you are trying to secure a release on bail, you must do so at the county level. This usually happens at the Los Angeles Inmate Reception Center (IRC) or in the courthouse handling the case, before the defendant is moved to state custody.

How to look up an inmate’s information

Family and friends can locate an inmate using the CDCR online inmate locator by entering the inmate’s full name or CDCR number. You can also call LAC’s main line at (661) 729-2000 to confirm housing and mailing details.

If you do not have the CDCR number, you can contact the CDCR Identification Unit at (916) 445-6713 with the inmate’s full name and date of birth to get help locating them.

How to contact someone being held at LAC

Calls are initiated by the incarcerated person. CDCR pays ordinary audio-call charges; family members do not need to fund those calls. Access, monitoring and duration rules still apply.

Use the assigned facility’s inmate-mail P.O. box, rather than the physical visiting address:

Incarcerated person’s full name, CDCR number and housing
California State Prison, Los Angeles County
Facility A and ASU: P.O. Box 4430
Facility B: P.O. Box 4490
Facility C: P.O. Box 4610
Facility D: P.O. Box 4670
Minimum Support Facility: P.O. Box 4730
Lancaster, CA 93539, with the matching box-specific ZIP+4

Always include the inmate’s CDCR number on the envelope and on any money orders or correspondence. All mail is screened before it is delivered.

Many inmates at LAC have access to CDCR’s electronic messaging system through an approved vendor. Friends and family must create an account with the vendor and be on the inmate’s approved contact list. Messages are monitored and may carry a small fee.

Use CDCR-approved trust-account deposit methods for commissary and other approved paid services. Audio calls are free. The official LAC page lists P.O. Box 8487, Lancaster, CA 93539-8487 for inmate money orders; follow the applicable payee and deposit instructions.

Visiting inmates at LAC

All visitors must be approved by CDCR before their first visit. Once approved, you can schedule visits through the CDCR Visitation Scheduling Application (VSA). Visiting days are generally offered on weekends and certain holidays. Weekend slots often fill quickly, so book early.

Visitors must bring valid photo identification and comply with CDCR’s dress code and security rules. Minors must be accompanied by an approved adult and may need a certified birth certificate and notarized consent if they are not accompanied by a parent or legal guardian.

How to get help for someone who has been arrested

By the time someone reaches LAC, they are typically serving a state sentence. However, there may still be opportunities for post-conviction motions, appeals, sentence reductions, or program-based credits that can shorten the time in custody. An experienced defense attorney can explain these options and advocate for the inmate’s rights.

Why does the housing assignment matter at Lancaster?

Purpose	Correct resource
Personal mail	Use the facility A, B, C, D or Minimum Support P.O. box above, with the CDCR number and housing.
Legal mail	The official LAC page separately lists P.O. Box 8457, Lancaster, CA 93539-8457. Counsel must follow confidential-mail requirements.
Visit	The physical address is 44750 60th Street West. Check current approval, appointment and restrictions.
Electronic contact	The August 21, 2026 CDCR schedule lists LAC as pending transition to Securus. Check the current platform before paying for messages or video.

The same name and CDCR number should appear consistently on letters and deposit records. Confirm the housing unit after a transfer; a correct prison name with the wrong P.O. box can delay delivery.
