About Ohio 811 (OUPS)
Ohio 811 (also known as OUPS — Ohio Utilities Protection Service) serves the entire state and operates one of the most digitally advanced one-call systems in the Midwest, with real-time ticket tracking through their online portal.
Submit tickets at https://www.ohio811.org or dial 811 from any phone.
Required Wait Period in Ohio
Ohio requires 3 full business days notice before excavation. The clock starts from the time the ticket is submitted and confirmed in the Ohio 811 system.
Use the Wait Time Calculator to find your exact dig date accounting for weekends and holidays.
Ticket Validity and Re-Notify in Ohio
Ohio's ticket validity window is 10 business days — measured in business days, not calendar days, making it effectively about 2 calendar weeks. This is shorter than most Midwestern neighbors. For any project lasting more than 10 business days, proactive re-notification is essential.
Private Lines in Ohio
Ohio has significant agricultural and rural areas with private well infrastructure, propane tank service lines, and grain bin power feeds — none of which are covered by 811. Urban and suburban Ohio properties frequently have irrigation systems.
