The American justice system establishes a jail as a correctional facility that holds inmates before their trials or those that have been incarcerated for a short time.

Moreover, if you cannot contact them, you can also reach out to their legal representatives. If the above means fail, there are many credible online search engines and tools to get you your desired results.

You can check the website of the facility in which they are housed. Most county jails, state prisons, and federal facilities have inmate locator tools that hold information about their inmates. The locator will not only present you with an inmate’s ID but also their release dates, crimes, arrest details, mugshots, among other bits of information that you could be looking for.

A DOC number is a six-digit number given to inmates by the Department of Corrections. If you want to trace an inmate’s identification number through a DOC website, you will be required to provide the same information that you would present on a BOP website. The relevant information, such as an inmate’s first and last name, will always lead you to a bank or other information about a specific inmate, including their ID number.

If you cannot exploit online means to get an inmate ID for whatever reason, you can still acquire this information through inmate call mail. When an inmate is sending a mail, they are expected to include their ID as part of the address, making the information readily available on the envelop whenever you need it. Even better, you can directly call the correctional facility where they are housed and request the ID number.

If online means are not available and the mail and call avenues are not accessibly at your disposal, you can choose to visit the jail or prison and inquire onsite. The prison staff will always help you accordingly. This might be an engaging avenue but will present you with the most credible information ever.

Can Inmate ID Change?

In most cases, inmate ID numbers remain the same throughout their sentences, depending on where they are housed. For instance, in federal facilities, the ID numbers will remain the same whether an inmate is transferred between two or more BOP facilities as long as their sentences remain the same.

This also applies to state, county, and city correctional facilities as long as the sentence remains intact, and you are transferred to the same level holding. However, for the ID to remain the same in case of transfers, you have to be held in a facility in the same state as your initial prison or jail. The ID could change if you are transferred to another state’s facility. Moreover, if you are release in one state and arrested in another, your initial ID will not count; you will get another one. If you switch between state and federal facilities, your inmate ID will also change.

Another outstanding case when your inmate ID might change is when you are transferred between different security facilities. If you are transferred from a minimum-security municipal prison to a high-security federal facility, your inmate ID will change. The level of the facility will also prompt an ID change.
