How to Contact an Inmate at Grenada County Jail, MS (MS)

The Grenada County Board of Supervisors lists two addresses for written correspondence or formal requests. The physical address is 59 Green St., Grenada, MS 38901. For mail, use PO Box 1208, Grenada, MS 38902-1208.

The Grenada County Board of Supervisors phone numbers are (662) 226-1821 and (662) 227-2860. These are general county lines, so you may need to ask for a transfer to the right office for jail-related questions.

The county page lists the Grenada County Sheriff as David Garrett Hartley. Names and roles change over time, but having the listed name can help you confirm you've reached the right office.

One contact point that comes up for families is medical and prescription billing. The Mississippi Association of Supervisors (MAS) uses Association Program Administrators, LLC (APA) as the Third-Party Administrator (TPA) for the MAS Inmate Medical/Rx Cost Containment Program. Under that program, APA adjudicates inmate medical and pharmacy bills to Medicaid rates and sends a monthly invoice and savings report to the county. The listed APA contact is Rob Tinsley, with a mailing address of PO Box 321418, Flowood, MS 39232 and phone 601-500-1631. This contact is strictly for billing and program administration, not general inmate messaging.

Steps to Follow

• ✓ Call (662) 226-1821 and, if needed, (662) 227-2860 to ask for the correct office for Grenada County Jail inmate communication questions.
• ✓ If you need to send a written request, use the Grenada County Board of Supervisors mailing address (PO Box 1208, Grenada, MS 38902-1208) or the physical address (59 Green St., Grenada, MS 38901), depending on what the county instructs.
• ✓ If staff ask which agency oversees the jail, reference the sheriff listing (David Garrett Hartley) so they can route you appropriately.

If you're reaching out about a medical or prescription bill tied to incarceration, contact APA directly. They serve as the TPA for the MAS Inmate Medical/Rx Cost Containment Program. The listed contact is Rob Tinsley. You can call 601-500-1631 or send mail to PO Box 321418, Flowood, MS 39232. APA's role is adjudicating bills (including adjusting to Medicaid rates) and handling county invoicing, so keep your request focused on billing, invoice questions, or where a provider should send documentation.

1. Call the county numbers and confirm you can reach the jail. Use (662) 226-1821 or (662) 227-2860 and ask whether that office can transfer you to Grenada County Jail staff who handle inmate calls, mail, or messaging.
2. Confirm the best address for your purpose. Ask whether you should use the physical address (59 Green St., Grenada, MS 38901) or the mailing address (PO Box 1208, Grenada, MS 38902-1208) for your specific request.
3. Ask for the jail’s exact mail rules before you send anything. Have them tell you what name and identifying details must be on the envelope, and whether there are restrictions on what can be mailed.

Use the sheriff listing (David Garrett Hartley) as a starting point, but verify current leadership and which office actually handles inmate communication questions. Depending on the issue, you may be routed to the jail, the sheriff's office, or county administration.

• ✓ Confirm APA is still the active TPA for Grenada County under the MAS Inmate Medical/Rx Cost Containment Program.
• ✓ Verify the correct APA contact details for billing questions (Rob Tinsley, PO Box 321418, Flowood, MS 39232; 601-500-1631).
• ✓ Ask what types of inmate medical and pharmacy billing issues APA handles (for example, bill questions, where providers submit bills, and how bills are adjudicated).
• ✓ Confirm whether families can contact APA directly, or if requests must go through the county or the facility.
