Sending a Mail/Care Package

The address to send mail to is:

Inmate Name, ID Number, Housing if known
​1702 St. Paul Street, Baltimore, MD, 21202

You can send letters and as many as 20 photographs up to 4” x 6” in size. Do not send Polaroid pictures or any picture that is sexual or violent in nature.

You can also send greeting cards to the Threshold as long as they are smaller than 8”x10,” and the card should be simple in design without any extra padding.

Sending Money

To send money, use a money order or cashier's check. You should make the cashier's check or money order payable to the inmate's name and ID number. On the check somewhere, include the Threshold, and housing unit, most likely you should put it in the memo field on the check.

Make sure you include your name and address on the money order.

You can send the money order directly to the inmate at the address above.

Phone calls

The easiest way to help an inmate make phone calls is by depositing funds into a pre-paid telephone account. This will allow an inmate to make phone calls to a landline or a cell phone, and he can even call internationally. Calls can be made for a duration of up to 30 minutes, and will be monitored by the Threshold staff.

To set up a pre-paid account, go to this link. You can also set up an account over the phone by calling 410-727-0100.

Visitation

You need to complete a visitor’s application and be preapproved as a visitor. You can access an application at this link.

Once you are preapproved, you will want to familiarize yourself with the rules for visitations. You can read through these rules by clicking here.

Remember that Threshold is a maximum security jail and you will need to dress conservatively and not bring in any materials to the prison.
