Call 811 Before You Dig in Mississippi

A fence line, a new driveway, a tree that has to come out, a generator pad before hurricane season. Digging is ordinary work on the Gulf Coast, and most of it happens in ground nobody has a reliable map of. Mississippi handles that with one free phone call. The requirement sits in Title 77, Chapter 13 of the Mississippi Code, and it applies to homeowners doing their own work as much as it does to crews.

What the law asks of you before you dig

Section 77-13-5 requires notice to Mississippi 811, Inc. not less than three and not more than ten working days before excavation starts. There is no charge for the ticket. The notice has to carry your name, address and phone number, who is responsible for the work, the start date, how long it will take, the type of excavation, the location, and whether explosives are involved.

The location matters more than people expect. A ticket is limited to the area you reasonably believe you can finish within 20 calendar days of the ticket being processed. Stretch a ticket across a month of weekend work and you have a problem the statute names specifically. Legal holidays don't count as working days, so a Friday ticket before a long weekend waits longer than you think.

Emergency excavation is the one exception. Where life, health or property is in imminent danger, or a customer's service is out, you don't need advance notice — but you still have to take reasonable care and notify Mississippi 811 as promptly as you reasonably can.

When you can skip the call, and why the rule is narrower than it looks

The statute defines "excavate," and the definition carves out a few cases. On private property, moving earth to a depth of less than 12 inches without mechanical equipment isn't excavation — whether you own the property or not, except inside a clearly marked utility right-of-way. Driving wooden stakes with hand tools that reach no more than six inches is also outside it.

Go past 12 inches, or put a machine in the ground, and you are back inside the law. A trencher, a mini-excavator, an auger on a tractor, a powered post-hole digger — none of them are hand tools. Fence posts, irrigation lines, footings and pool walls all go deeper than a foot.

Treat the 12 inches as a legal line, not a safety line. It tells you when the law stops requiring a call. It says nothing about where the gas service or the fiber actually runs, which is often shallower than the drawing shows.

What happens after you call

Dial 811, or (800) 227-6477, any hour of any day. Mississippi 811 is in Pearl, and its office hours are Monday through Friday, 7 a.m. to 5 p.m., for anything beyond the ticket itself.

Operators then have three working days from the time your ticket is processed to either mark their facilities in the area or tell you through the system that they have nothing there, under Section 77-13-9. Marks follow the standard APWA colors — yellow for gas, orange for communications, red for electric, blue for water, green for sewer.

Don't schedule the crew for the next morning. Three working days is the outer limit the law allows them, and a ticket that lands Thursday before a holiday weekend runs into the following week.

The 18-inch tolerance zone

Section 77-13-3 defines the "approximate location" an operator gives you as accurate within 18 inches, measured horizontally from the outside edge of the facility, or a strip 18 inches either side of the field mark. Mississippi 811's own guidance is direct: work inside that zone with hand tools until the marked facility is exposed.

So the paint and flags mark a band, not a line. Digging a foot to the side of a yellow mark is still digging inside the tolerance zone, and a machine there is how service lines get cut.

Lines inside your property line aren't on the ticket

The marking duty belongs to the operators of the facilities — the utilities that own them. They mark what they own, which is generally up to the meter. Mississippi 811 addresses this directly in its FAQ on why utilities mark only to the meter.

That leaves the rest to you: the line from the meter to the house, irrigation and sprinkler runs, landscape lighting, a feed to a shed, dock or detached garage, pool plumbing, propane lines you own past the tank. Nobody is going to paint those. If you don't know where they run, don't assume the ground is empty because no flags went down.

If you're hiring the digging out, this is the point to ask what the contractor knows about private lines on your property.

If your shovel finds something

Section 77-13-7 is short and strict. On discovery of damage, notify Mississippi 811 and every operator of the damaged facility immediately, tell them where the damage is, and give them reasonable time to repair before you finish work in that spot.

If the damaged line is carrying gas or any hazardous, flammable, toxic or corrosive material, call 911 first. Then notify Mississippi 811 and the operator, and keep people away until their crew and the fire department arrive. A severed gas service is not a call-the-utility-tomorrow situation.

Giving notice does protect you. Section 77-13-13 relieves you of liability to a utility if your notice was ignored or the information they gave you afterward was materially wrong. It does not excuse careless digging. The statute says so in as many words.

What skipping the call costs

Enforcement runs through the Underground Facilities Damage Prevention Board. Under Section 77-13-27, a first violation means completing a training course at your own expense. A second violation within five years means training, a civil penalty of up to $500 per incident, or both. A third or later violation within five years carries up to $2,500 per incident. Where the violation came from gross negligence or willful misconduct, the penalty reaches $5,000 plus training.

The board can also order an excavator to stop work, or refuse to let a proposed excavation start, until the law is satisfied. Separately from any of that, there's the bill for the repair, the cost of an outage, and whatever the emergency response costs.

When the contractor is doing the digging

The ticket belongs to whoever is excavating, so the contractor files it — not you, and not the neighbor whose fence shares the run. Before work starts, ask for the ticket number and ask what came back marked. A contractor who can't produce a ticket number is telling you something.

If you haven't picked one yet, verify the contractor's license against the MSBOC database and search the directory by trade and city to see who's listed near you. Our guide to hiring a contractor safely covers what else to ask before you sign.

A fence or a driveway may also need a permit from your city's building department on top of the 811 ticket. Those are separate steps, and one doesn't cover the other.

One call, three to ten working days ahead, free. That's the whole ask.
