Ohio law requires that everyone must contact the Ohio Utilities Protection Service at least 48 hours, but no more than 10 working days (excluding weekends and legal holidays), prior to beginning ANY digging project. The toll-free number is (800) 362-2764. If you have a personal computer and Internet access, you may enter excavation notices remotely through e-dig,  O.U.P.S' Internet-based ticket entry system for homeowners, at www.oups.org.
