Contra Costa County, California · Jail custody, police reports and criminal court records
Find the Booking First, Then Verify the Contra Costa Court Case
A Contra Costa County arrest can create separate Sheriff custody records, police reports, bail entries and Superior Court documents. Those records do not always update together.
Start with live custody, preserve the booking identifiers, identify the arresting agency and then verify the prosecutor’s filed charges and final disposition.

BOOKING → REPORT → DISPOSITION
Arrest does not mean conviction. A booking charge records an allegation connected to custody. The District Attorney may decline, replace or amend charges, and the court may dismiss a count or find the defendant not guilty.
Current custody
Use the Sheriff’s In-Custody Locator.
Past booking
Request an out-of-custody record from Records & ID.
Police narrative
Request it from the agency that made the arrest.
Final outcome
Verify it through Contra Costa Superior Court.
DOJ self-review
California Record Review processing fee: $25.
Which Contra Costa County record do you actually need?
SHERIFF CUSTODY
Is the person jailed now?
Use the In-Custody Locator for the current booking, booking number, facility and custody-related information.
Best first stop after a recent arrest.
CUSTODY RECORDS
Was the person released?
Historical or out-of-custody requests are handled through the Sheriff’s Records & ID process.
A missing live result can simply mean release or transfer.
ARRESTING AGENCY
What did officers report?
Request the incident report, arrest report or releasable supplements from the police or Sheriff unit that created them.
The jail does not automatically own the police narrative.
SUPERIOR COURT
What happened to the charge?
Research the criminal case and obtain the complaint, orders, disposition or judgment when formal proof is required.
Use this to separate an allegation from a conviction.
CALIFORNIA DOJ
What is on my state record?
Request your own fingerprint-based California criminal history for accuracy review.
Another person’s complete DOJ summary history is confidential.
Fastest reliable sequence: current custody → booking number → arresting agency → criminal court case → final disposition.
How to search the Contra Costa In-Custody Locator
Open the official Sheriff locator
Use the Sheriff website rather than a paid people-search page.
Open the In-Custody Locator
Search by booking number when you have it
A booking number is more precise than a common-name search.
Otherwise begin with the legal name
Try the surname first when the middle name, suffix or spelling is uncertain.
Open every plausible result
Do not assume that the first matching name belongs to the person you are researching.
Verify the booking event
Compare the booking number, arrest date, facility, charge information and other displayed identifiers.
Record the current detention facility
Contra Costa custody can involve Martinez, West County or Marsh Creek facilities.
Save every charge and bail entry separately
One person can have several allegations, court cases, warrants or holds.
Do not stop at the booking result
Continue to Superior Court records to learn what prosecutors actually filed.
24-hour inmate-information help: 925-646-4496. The Sheriff’s general Inmate Information page also routes users to current custody, reports, visits, commissary, deposits and mail.
How to find a Contra Costa arrest after release
A person disappearing from the live locator does not mean the arrest never happened or the case was dismissed.
Search current custody one last time
Confirm the person is not merely housed at another Contra Costa detention facility.
Record everything already known
Save the full legal name, date of birth, arrest date, booking number, agency and court case number.
Use the correct custody-record email
For a person still in custody, use csbrecords@so.cccounty.us.
Use Records & ID after release
For an out-of-custody record, use recordsinfo@so.cccounty.us.
State the exact record needed
Ask for the booking/custody record connected to the known booking date instead of requesting “everything.”
Continue to court even if the jail record is unavailable
A criminal case can remain searchable after the custody record is no longer visible online.
Copy-ready historical custody request
I am requesting the releasable custody or booking record for [full legal name], date of birth [date], connected to an arrest or booking on or about [date]. Known identifiers are booking number [number], arresting agency [agency] and court case number [number]. Please provide the record electronically when available and advise of any required fee before processing.
What Contra Costa jail fields mean
| Field | What it identifies | What it does not prove | Next step |
|---|---|---|---|
| Booking number | A specific county custody event. | The final court charge. | Save it for jail, mail, money and records questions. |
| Booking date | When county intake was recorded. | When the alleged conduct occurred. | Compare it with the police report and court filing. |
| Facility | Where the person is presently assigned. | The person will remain there. | Recheck before visiting or mailing legal documents. |
| Arresting agency | The law-enforcement agency responsible for the arrest. | The Sheriff created the incident report. | Request the narrative from the listed agency. |
| Charge | An allegation entered during arrest or booking. | What the District Attorney ultimately filed. | Compare it with the complaint or information. |
| Bail amount | A bail entry associated with the case or charge. | Payment will clear every hold. | Confirm every case and detainer first. |
| Hold or warrant | Another court or agency may affect release. | The local bail amount controls release. | Identify the agency that owns the hold. |
| Release | The end of the displayed custody event. | Dismissal, acquittal or innocence. | Read the Superior Court disposition. |
| Booking photo | An image associated with custody when displayed or releasable. | Guilt or identity by itself. | Match official numbers and biographical details. |
Verify the right person before relying on the arrest record
Full first and last name are consistent
Middle name, alias or suffix is consistent
Date of birth or age matches
Arrest date matches the known incident
Arresting agency matches the location
Booking number matches another record
Court case follows the same event
Facility and custody timeline make sense
Minimum identity rule: Match at least two independent identifiers before publishing an allegation, sending money or treating the result as belonging to a particular person.
No Contra Costa County arrest result? Check these causes
Booking is still being processed
Identification, medical intake, property inventory and data entry can delay a new result.
The person was already released
Request an out-of-custody record and continue to court records.
The spelling is different
Try a former name, maiden name, hyphenated surname, suffix or alternate spelling.
A city police department made the arrest
The detailed police report may be held by Concord, Richmond, Antioch, Pittsburg, Walnut Creek or another city agency.
The arrest occurred outside Contra Costa County
Search the county where the person was actually taken into custody.
The person was transferred
Check another county, California state prison or federal custody when the local custody period has ended.
No court filing appears yet
Prosecutor review and court filing can occur after the initial arrest.
The record is legally restricted
Juvenile, sealed and other protected records may not be publicly available.
Missing-booking call script
I am trying to confirm the custody status of [full legal name], date of birth [date]. The arrest may have occurred on [date] through [agency]. Can you confirm whether the person is currently being processed, housed at another Contra Costa facility, released, transferred or listed under another booking number?

Confirm the Sheriff created the report
The Records & ID Unit maintains Sheriff reports for unincorporated areas and Sheriff contract cities.

Ask for the incident report, arrest report or specifically identified releasable supplement.
Use the report number when known
A report number reduces mistaken records and unnecessary searching.

Include the booking number, full legal name and arrest date.
Bring valid identification for counter services
The Records Unit requires valid ID and states that a DMV renewal paper receipt is not accepted as identification.
Prepare the accepted payment type
The office states that counter fees are paid by exact cash or check; credit and debit cards are not accepted there.
Allow for the records-response process
The Sheriff states that the Records Unit has ten days to respond to requests.

Who maintains each Contra Costa arrest record?
| Record | Likely custodian | Use these identifiers | Avoid this mistake |
|---|---|---|---|
| Current custody | Contra Costa Sheriff Custody Services | Name and booking number. | Searching the Superior Court for live housing. |
| Historical county booking | Custody Services / Records & ID | Name, birth date, arrest date and booking number. | Assuming a released person should remain on the live locator. |
| Sheriff incident report | Sheriff Records & ID Unit | Report number, date and location. | Requesting it from the jail cashier or court clerk. |
| City police report | The municipal police department | Agency report number and incident details. | Sending every report request to the Sheriff. |
| Formal charges | Contra Costa Superior Court / District Attorney | Criminal case number and defendant name. | Treating the jail allegation as the final charge. |
| California RAP sheet | California Department of Justice | Fingerprint-supported personal request. | Trying to obtain another person’s complete DOJ history. |
Verify the formal charge and final court disposition
The jail booking is not the final criminal court record. The court complaint, amended filings and final disposition control the legal outcome.
Open the court’s Criminal Records page
Use the official court instructions to access the public portal or request records.
Open Contra Costa criminal records
Use the case number when known
A case number is safer than a name search when several people share the same name.
Confirm the defendant and courthouse
Contra Costa criminal matters can be handled in Martinez, Pittsburg or Richmond.
Identify the formal complaint or information
Compare the prosecutor’s filed counts with the original booking allegations.
Check amended charges
Counts can be added, reduced, replaced or dismissed after filing.
Read warrant entries chronologically
An issued warrant may later be served, recalled or otherwise resolved.
Find a disposition for every count
One charge may be dismissed while another results in a plea or conviction.
Request documents when the online summary is not enough
The court states that minutes, case documents and orders may require a records request.

Ask the recipient whether certification is required
Do not automatically pay a certification fee for a personal-reference copy.
Use the current criminal-record request form
Follow the court’s mail and payment instructions.
Get the current court records forms
Confirm every charge and hold before arranging bail
The court’s criminal page currently publishes felony and misdemeanor bail schedules, but a schedule is not a substitute for the defendant’s current court order. Bail can change after judicial review.
Release on recognizance
The court may permit release without depositing money, subject to appearance and other conditions.
Cash bail
A specified amount may need to be deposited using the authorized court or custody procedure.
Surety bond
A licensed bail agent may arrange the bond subject to the agreement, premium and any collateral.
Hold or detention
Another warrant, court case or detention order can prevent release despite a displayed amount.
Confirm the booking number
Match the full legal name and the correct custody event.
List every active charge
Do not assume one bail figure resolves the entire booking.
Ask about every hold
Determine whether another county, state agency, court or federal authority controls release.
Confirm the newest court order
The amount in the initial booking data may differ from the later judicial order.
Ask where payment must be completed
Obtain instructions from the current jail or Superior Court before sending funds.
Verify a private bail agent
Check the California license and obtain the premium, collateral and refund terms in writing.
Keep all receipts
Save the payment confirmation, bond contract, court case number and booking information.
Allow release processing
Release can take additional time while staff verify the order, clear holds and complete property paperwork.
Bail verification script
I am calling about booking number [number] for [full legal name]. Please confirm every active case or charge, the current bail or release condition for each one, any outside holds, and the approved method and location for completing the release process.
