Everyday Inmate Life in the Facility

Any person that is incarcerated in the Threshold in Baltimore is eligible to participate in programs to help them succeed legally in life. This includes classes for mental health, GED, education courses, and substance abuse treatments.

To ensure that staff and inmates are safe, the Threshold adheres to a very strict schedule. If the schedule is not maintained, it can lead to a rough day for all involved.

Upon arrival to the facility, an inmate will be in the reception center. It could take 120 days for them to get out of the reception center. While they are in this part of the facility, they will not have phone privileges, but you can send mail and writing supplies. They are also allowed to have visitors as long as they are on the approved list.

At this time, inmates will be placed into a security level and groups. After reception, an inmate will be assigned to an institution within the prison. This is why doing an inmate search is important. Doing regular inmate searches will help you to know where an inmate is at all times.

Of course, the first step in being there for an inmate is to find out exactly where they are within the facility. Since there are different inmates with different rules and regulations, you will need to do an inmate search.

Once you find the inmate you are looking for, you can click on their name to get more information. Write down their ID number and their location. You will need this information later.

Staying in Contact with an Inmate

Part of the rehabilitation of inmates includes them staying in contact with positive, law abiding family and friends. Research has shown that inmates who have a support system on the outside are more likely to be rehabilitated and not end up back in prison.

Because friends and family are such a crucial part of the rehabilitation process, the Threshold gives plenty of opportunities for you to stay in contact with loved ones who have been incarcerated.

How to send mail

Sending mail is still one of the best ways to stay in contact with the incarcerated. When an someone is in prison, they look forward to daily and even weekly mail. However, to ensure an inmate receives mail, you must address it in the following way:

Name, Inmate’s#


Facility, Building #, Cell #

1702 St. Paul Street, Baltimore, MD, 21202

Be sure to always include a return address. Mail will be searched before getting to the inmate.

How to call

You will not be able to call an inmate. However, depending on their privilege group and as long as they are not in the Administrative Segregation Unit. Inmates at the Threshold are allowed to make collect calls. If they are calling a cell phone or prepaid phone line, you will want to set up a collect calling account with ConnectNetwork.

How to visit an Inmate

Visiting an inmate is also another great way to help them with their rehabilitation. In order to maintain security and protection, you will need to register. Without scheduling an appointment, you will not be allowed to visit the inmate. Follow these steps when choosing to visit an inmate:

  1. Read Visitation Guidelines to understand what you can expect and what is expected of you

  2. Find out in which facility your inmate is housed by doing an inmate search.

  3. Schedule a visit online.

  4. The day of your scheduled visit, check the Visiting Status to ensure the institution is accepting visitors.

How to send money

If you wish to send money to an inmate to help them make purchases in commissary, you can do so. There are three ways you can send money to an inmate:

  1. Lock Box: A no fee service with a shorter hold time for sending money via money order, personal check, or cashier’s checks. You must use a deposit slip.

  2. EFT (Electronic Funds Transfer): A paid service, this is the fastest option with funds posted to inmate’s account within 1 to 3 days.

  3. Mail funds directly to the Threshold: Never a fee. All funds are subject to a 30 day hold. You will want to make funds payable to the Maryland Department of Corrections. The senders name and address must be written on the check/money order along with the inmate’s name and number.

Please keep in mind that all procedures and regulations are put in place to keep inmates, staff, and the community safe.
