How to Send Money to Martinez Detention Facility (CA)

To add money to someone's account at Martinez Detention Facility, you'll need to use a money order or cashier's check. These are the only forms the facility accepts. Using the right one from the start saves you from delays or rejected mail.

Do not send cash or a personal check. If you do, the facility will return the envelope and everything inside it to the sender.

For context: Inmate services and programs are funded through the Inmate Welfare Fund (IWF), which gets its revenue from commissary sales and Inmate Industry operations. The money you send goes directly to your loved one's account, separate from how the facility funds its programs.

1. Choose an approved payment type. Use a money order or a cashier’s check.
2. Fill it out clearly. Make sure the inmate’s name and booking number are written on the front so staff can credit the right person.
3. Avoid rejected forms. Do not mail cash or a personal check, since it will be sent back to you.

Before mailing anything, confirm the current deposit rules with Martinez Detention Facility. Check the official county sheriff information page or call the facility directly. Policies can change, so verify which payment forms are accepted right now.

You can also ask what happens if an unapproved payment type arrives. Cash or personal checks get returned to the sender.
