An inmate ID number is a unique identifier assigned to each individual who is incarcerated within a correctional facility, such as a prison or jail. This number helps prison staff and administrators keep track of inmates within the system. It is used for various purposes, including record-keeping, identification, tracking movements within the facility, and accessing information related to the inmate’s case, such as their charges, sentence length, and disciplinary history. The inmate ID number is typically assigned upon intake into the correctional facility and remains associated with the individual throughout their period of incarceration.
