What is an MPI number and where can I get one?

Every participant in a CSE case is assigned a Master Participant Index (MPI) number, a unique 10-digit identification number. Your MPI number appears on your payment coupons. If you do not have a payment coupon, CSE Customer Service Center at 1-800-992-9457 from 7:30 a.m. until 7:30 p.m., Monday through Friday or contact Guilford County CSE.
