From ATG, LLC:
CorrLinks is a way for family and friends to electronically communicate with their loved ones incarcerated in institutions. Established through a relationship between a corrections agency and ATG, this system allows family and friends to subscribe to CorrLinks services. Currently all Federal Bureau of Prisons and Department of Corrections (DOC) for the States of Iowa and Oklahoma institutions, as well as Minnesota allow such communication. Note: To use this app, you must have a paid Premier Account subscription.
