How to Contact an Inmate at Saint Louis County Jail (MO)
Getting in touch with someone at Saint Louis County Jail means using the jail's approved phone, account, and mail systems. Start with the county's own pages, then follow the links they provide to outside services.
Saint Louis County Jail has county webpages for Inmate Phone Usage, Cash Accounts, and Mail. Each page, though, sends you to an external website to actually complete the process. The county makes clear you're leaving their site and that they may not control what's on those linked pages. This matters because the details you need (how calls work, how to add money, what mail is allowed, fees and limits) are explained on those external service pages, not the county page itself. If something seems unclear or contradictory, take that as a cue to verify before spending money or mailing something you can't get back.
Steps to Follow
- ✓ Open the Saint Louis County Jail county pages for Inmate Phone Usage, Cash Accounts, and Mail.
- ✓ Follow the external link on each page to see the current instructions for phone calling, adding funds, and sending mail.
- ✓ Use the external site’s rules and steps for that specific service, since that is where the county directs you for setup and details.
- ✓ If something looks outdated, confusing, or different from what you were told, confirm the current process with the jail before you act.
- Confirm the phone service details: Ask whether the external phone instructions currently match what Saint Louis County Jail is using, and whether there are calling limits, fees, or account requirements.
- Confirm how money is handled: Verify that the cash account process on the external site is current, including any deposit limits, transaction fees, or restrictions on who can add funds.
- Confirm mail rules before sending anything: Check that the external mail instructions reflect current jail practice, including what is allowed, what is rejected, and any formatting requirements (name, ID number, return address).
- Double-check any “last updated” gaps: If the external site looks generic or you cannot find Saint Louis County Jail specifically, pause and confirm through the county site’s official contact options before relying on it.
Note: The county's Phone Usage, Cash Accounts, and Mail pages all link to third-party sites, and St. Louis County notes it may not control their content. For anything time-sensitive or expensive, verify current rules directly with Saint Louis County Jail before relying on a third-party page.
