When you receive a call from a correctional facility or jail, the number that shows up on your caller ID is often a generic number associated with the facility, rather than the specific number of the inmate who is calling [1]. This is done for security and privacy reasons.

It's important to note that the specific number that shows up on your caller ID may vary depending on the correctional facility or jail. Some facilities may have a dedicated phone line for inmate calls, while others may use a third-party service to handle the calls.

If you have questions or concerns about receiving collect calls from individuals in custody, it is recommended to contact the relevant authorities or service provider for more information. For example, you can call Securus at (1-800-844-6591) for information on receiving collect calls from individuals in custody [3].
