Prisoners' Legal Services (formerly known as Massachusetts Correctional Legal Services) was established in 1972 to provide legal services to people in Massachusetts prisons and jails. PLS addresses problems through administrative advocacy, legislative advocacy and litigation.
PLS accepts collect calls from prisoners and people concerned about prisoners on Monday afternoons from 1:00 p.m. to 4:00 p.m. If Monday is a holiday phone hours are on Tuesday. Massachusetts state prisoners should call 9004, which is a speed dial number that is pre-approved on the PIN cards of all state prisoners. Prisoners in county jails and houses of correction should call collect at (617) 482-4124. Family members and friends of prisoners may call (617) 482-2773. Prisoners can write to PLS any time at 50 Federal Street, 4th Floor, Boston, MA 02110.
