Yes, and this is one of the less talked-about benefits of the service.
When an inmate makes calls through the facility's phone carrier, every number they dial has to be submitted and approved in advance. That approval process requires the person on the outside to register their phone number with the carrier, which means your name, number, and in some cases your address go into that system. For people on a family plan, a work phone, or any situation where the number is shared or sensitive, that registration creates complications that can be hard to explain.
With InmateAid's phone service, your inmate dials the InmateAid number instead of your personal number. The InmateAid number is what gets registered with the facility's phone carrier, not yours. Your actual number stays out of the prison phone system entirely. The call routes through to you on the back end, but the carrier never sees your personal number, and it never appears in the inmate's approved call list under your name.
For anyone navigating a family plan where other people might see incoming call logs, or for anyone who simply does not want their personal number tied to a prison phone account, this is a real and practical advantage. The savings on the per-call rate are the main selling point, but the privacy benefit is worth knowing about too.
