The Inmate Telephone System is available for outgoing inmate calls only. Inmates are not allowed to receive incoming telephone calls. The system is contracted with a vendor named Value Added Communications, a wholly owned subsidiary of Global Tel*Link (GTL). In most cases GTL must be contacted to initiate any service, which has these categories:

  • Personal Outgoing Calls—inmate conversations with family and friends which are recorded and monitored.

  • Legal Outgoing Calls—inmate conversations with legal counsel which are not recorded nor monitored.

Unless there are security or disciplinary restrictions placed upon a jail, or an area within a jail, telephones are available to inmates from approximately 7:30 a.m. to 10:00 p.m. However, times vary for each facility, and some units allow 24 hour access to telephones.

Personal Outgoing Calls
  • Personal inmate calls are recorded and monitored.
  • The maximum allowable call length is 15 minutes for local calls and 20 minutes for long distance calls.
  • Inmates are not permitted to ask you to make third party or conference calls. Three-way call attempts will automatically alert the phone system, and the call will be disconnected.
  • Local and Long Distance. Direct calling is offered to countries using the North American Numbering Plan. This plan includes the United States and its territories, Canada, Bermuda, and 18 Caribbean countries. Collect calling is also offered to Mexico (Country Code 52).
  • International. Inmates can purchase a calling card from the Canteen for international calls only (calls that require entering a country code). This includes Mexico and all other countries outside the North American Numbering Plan. These international cards cannot be used for any calling within this numbering plan (U.S., Canada, etc.).

Billing Arrangements. The system offers family and friends two types of billing programs for personal calls: Collect Calls and AdvancePay Service.

Collect Calls
Inmates can place collect calls to numbers that have been set-up in the system when the call is accepted and paid by the receiving party. Unless an AdvancePay account is established, inmates cannot place collect calls to cell phone numbers or numbers that are blocked from receiving collect calls. Your service provider must also have a billing contract with the inmate telephone service provider (GTL).

When an inmate attempts to call a telephone number for the first time that will not accept collect calls, the called party receives an automated voice prompt offering a connection to the vendor's account center so that the called number can be registered in the system. There is also a voice prompt offering a one minute one-time courtesy call.

AdvancePay Service
If calling collect is not possible or not preferred, you can pre-pay for the calls by establishing an AdvancePay account with GTL. This type of account is a requirement for calls to cell phone numbers or if a large number of inmate calls are accepted. You can either go online or call GTL to: create a pre-paid telephone account, add funds, and check balances. All information is available in both English and Spanish.

Legal Outgoing Calls
Legal calls are not recorded nor monitored. The maximum call length for a legal call is 20 minutes. The Inmate Telephone System recognizes only the published telephone numbers of attorneys registered with the State Bar of Arizona, and the conversation is then classified as a “Legal Outgoing Call”. At the beginning of the call you will hear, “… (telephone company name) has a legal call from (inmate name)…”

If the system has not been updated with recently changed or new telephone numbers, you may hear “If this call has been placed to legal counsel, please hang up and notify the Sheriff’s Office at 602-876-1202.” In this situation, do not accept the call and notify our office immediately. The new telephone number will be verified with the State Bar of Arizona and added to the Legal Telephone database.

It is possible for inmate calls to be made to the cell phone of an attorney. However, an account with GTL must be established by using the information in the section above that covers personal calls. It is important to note that those calls, and most other calls to non-published attorney telephone numbers, do not fall into the category of “Legal Outgoing Calls”, and therefore they will be recorded.

If you require additional information regarding legal calls, please call 602-876-1662 from 7 a.m. to 3 p.m., Monday through Friday (except holidays), Mountain Standard Time. You may also leave a message at 602-876-1202 at any time, and your call will be returned.

Blocking or Unblocking Telephone Numbers
You can block your number so that inmates at the Maricopa County Sheriff’s jails cannot call.
  • Telephone Procedure: If you receive a call from an inmate and you do not want to accept that call or any future calls from the jail, you can block calls by pressing 7—6 when prompted by the recording.
  • Written Request: You can also request that your phone number be blocked or unblocked from the Inmate Telephone System by mailing or faxing a written request. The communication must include:
  • The requestor’s name
  • The phone number(s) to be blocked or unblocked
  • The inmate’s name and booking number (if known)
  • A brief reason for the request
  • A copy of a portion of a telephone bill that shows the name, account number, and the telephone number to be blocked or unblocked
