Inmate Money Accounts

How Do You Deposit Money for an Inmate in the Sonoma Main Adult Detention Facility?

There are FOUR options for putting money on an inmate's books:

Option 1 - Dropping Money at the Jail
Bring money to the jail in person. 
Either the jail personnel will process the Inmate Account payment or you will use a Jail ATM self-serve kiosk in the lobbies that accepts cash, debit or credit cards.

Option 2 - Deposit Inmate Money Online
Sonoma Main Adult Detention Facility uses Jail ATM to process all online deposits to an inmate's account. The company charges you a small fee for doing so, but the fee probably isn't as much as gas and parking would cost to take it to the jail in person.

Option 3 - Mail the Inmate Deposit to the Jail
Mailing a deposit takes more time to process than the other methods but can be done if you live too far away to bring it in person and you don't have a debit/credit card for online deposits. Never send cash. Always send a Money Order from the US Post Office, a reputable bank or Western Union. Call the Sonoma Main Adult Detention Facility first as they may want you to do this online or at the jail kiosk instead.
Make the Money Order out to the inmate's name and put their Inmate ID# in memo section of the Money Order.
