Maricopa County Jail Inmate Communication Overview
Maricopa County Jail is the detention system operated by the Maricopa County Sheriff's Office in the Phoenix metropolitan area, the fourth-largest county by population in the United States. The system encompasses multiple facilities including the downtown Phoenix intake complex and several satellite jails spread across the Valley. With a total capacity exceeding 8,000 and a daily population that routinely approaches that number, Maricopa County's jail system is one of the largest in the country. The vast majority of people held in the system are pretrial detainees awaiting court proceedings in the Maricopa County court system.
Communication across Maricopa County jail facilities is managed through GTL, which provides phone calls, video visitation, and electronic messaging services under the sheriff's office contract. Families can create a single GTL account to access all available services. For phone calls, setting up a GTL prepaid account linked to your phone number allows you to receive inmate-initiated calls. Remote video visits are available and can be scheduled through the GTL platform. Electronic messaging through GTL delivers messages digitally within the system. Commissary deposits can also be processed through GTL or AccessCorrections.
One thing to know about the Maricopa County system is that it operates several distinct jails, and your loved one may be housed at any of them — the downtown 4th Avenue Jail, Towers Jail, Madison Street Jail, or one of the other facilities. The GTL platform and account setup are the same across all Maricopa County Sheriff's Office facilities, but confirming the specific facility and booking number is important when scheduling video visits or making deposits. After a conviction and sentencing, inmates transferred to the Arizona Department of Corrections state system will require a switch from GTL to JPay and Securus.
