Frequently asked questions
Before you act
InmateLink is independent. It does not run person searches, display custody records, collect facility funds, provide legal advice, or represent a facility, government agency, court, bail company, or law firm.
Use only the reviewed external lookup link shown on this profile, when one is available.
Confirm visiting, mail, phone, money, and property rules with the facility before acting.
Bail listings are city-level public directory entries, not distance rankings, recommendations, availability, or proof that a company serves this facility.
Do not rely on old screenshots, third-party posts, or saved instructions after rules change.
