A jail engine number (also called a jail engine or prison engine) is a local Australian phone number that connects directly to your mobile. When a prisoner calls the jail engine number from inside a correctional centre, they pay a local call rate — typically $0.30 to $0.40 per call — instead of expensive mobile rates that can cost up to $0.90 per minute.
Engine Numbers has provided jail engine numbers to Australian families since 2004. We are Australia’s original and most trusted jail engine service, with over 30 million calls connected across NSW, VIC, QLD, SA, TAS, and ACT prisons.
How a Jail Engine Number Works
- You sign up for a jail engine number local to your loved one’s prison
- The prisoner calls the jail engine number from the prison phone
- The prison system charges a local call rate ($0.30–$0.40)
- The call connects straight through to your mobile phone
- No apps or special equipment needed
Why Families Choose Engine Numbers
Calls from Australian prisons to mobile phones are expensive — up to $0.90 per minute. A jail engine number solves this by giving the prisoner a local number to call, reducing the cost by up to 80%. Our jail engine plans start from just $6.50 per week for unlimited calls, with no lock-in contracts.
