What an 811 ticket lookup does and why you need it
An 811 ticket is a reference number issued when you call 811 to report that you plan to dig. The ticket tracks your request through the entire process — from the moment you call until the utility locating crews finish marking underground lines at your site. A ticket lookup lets you check the status of that request without calling back, see which utilities have responded, and find out whether the marking is complete.
You need a ticket lookup when you want to confirm that crews are actually coming, when you're waiting to know if it's safe to start digging, or when you need proof that you called 811 before you began work. The lookup also shows you the ticket number itself, which you'll need to reference if you contact 811 again about the same job.
Key Takeaways
- Each state's 811 center runs its own ticket lookup system, so you search on your state's website, not a national one.
- You can look up a ticket using the ticket number, your phone number, or your address, depending on which state you're in.
- The lookup shows you the status of each utility's response and whether marking is complete, but does not tell you when crews will arrive.
- Most state systems are free and available 24 hours a day, though some states limit lookups to business hours.
- If you cannot find your ticket online, calling 811 directly is faster than trying multiple search methods.
How to find your state's 811 ticket lookup system
Each state operates its own 811 center and maintains its own ticket database. There is no single national lookup tool. Start by going to the website for your state's 811 center — the easiest way is to search "[your state] 811 ticket lookup" or "[your state] call before you dig."
Common state 811 centers include Dig Safe (Massachusetts, New Hampshire, Rhode Island), Miss Utility (Michigan, Ohio, Indiana, Kentucky), Sunshine 811 (Florida), and One Call Concepts (serves multiple states in the South and Midwest). If you're unsure which center serves your area, you can call 811 from any phone and the dispatcher will route you to the correct state center — they can also tell you the web address for your ticket lookup.
What information you'll need to search
Most state systems ask for one of three pieces of information: your ticket number (if you have it), your phone number (the one you called 811 from), or your street address. Some states require the exact ticket number; others let you search by any of these fields. If you have the ticket number, that's the fastest route — it's usually printed on a confirmation email or text message sent right after you called.
If you don't have the ticket number, use the phone number you called 811 from. The system will pull up all tickets associated with that number from the past 30 to 60 days (the window varies by state). If you search by address, the system may return multiple tickets if you've called 811 more than once for the same location, so be ready to identify the correct one by date.
Reading your ticket status and what each stage means
Once you pull up your ticket, you'll see a status for the overall request and separate statuses for each utility company. Common statuses include "Received" (811 has logged your request), "Notified" (utilities have been contacted), "Responded" (a utility confirmed it has lines at your location), and "Marked" (crews have finished marking). Some systems also show "No Response" for utilities that didn't reply within the required timeframe.
The overall ticket status moves through these stages in order: first it's received, then utilities are notified, then they respond, and finally marking is complete. You should not dig until the ticket shows "Marked" for all utilities that responded, or until the required waiting period has passed (usually two to three business days). If a utility shows "No Response," that typically means either they don't have lines at your location or they didn't respond in time — your state's rules determine whether you can proceed.
When the lookup shows marking is complete
Once your ticket shows "Marked," the underground lines at your site have been located and painted or flagged. The marks are usually valid for 30 days from the date they were made — if you don't dig within that window, you should call 811 again for a fresh marking. The ticket lookup will show you the date the marking was completed, so you can calculate when the marks expire.
Before you dig, walk the entire area and look for paint, flags, or stakes. If you see marks that are faded, unclear, or missing in spots, call 811 again and reference your ticket number — they can send crews back to refresh or complete the marking. Do not assume a utility has no lines just because you don't see a mark; if the ticket shows "Responded," that utility confirmed it has infrastructure there.
What to do if your ticket doesn't appear in the lookup
If you search and get no results, the most common reasons are: you called 811 very recently (some systems take a few minutes to update), you're searching in the wrong state's system, or you're using information from a different ticket. Try searching again in 15 minutes, or try a different search field — if you searched by address, try by phone number instead.
If the ticket still doesn't appear after 30 minutes and you're certain you called 811, call 811 again directly. Have ready the date and time you called, your phone number, and your address. The dispatcher can look up your call in their system and give you the ticket number over the phone, or they can resubmit your request if the original call was not logged. This is faster than troubleshooting the online lookup further.
Limitations of the online lookup system
The ticket lookup tells you whether marking is complete, but it does not tell you when crews will arrive. Some states show an estimated arrival window; most do not. If you need to know a specific time, you have to call 811 directly or contact the individual utility company. The lookup also does not show you a map of where the marks are — you have to visit the site in person to see them.
Additionally, the lookup is a snapshot at the moment you check it. If you look at your ticket in the morning and see "Marked," but then it rains heavily and washes away the paint, the online status won't update to reflect that. Always do a final visual check of the site when ready before you dig, regardless of what the ticket status says.
Frequently Asked Questions
Can I look up someone else's 811 ticket?
No. Most state systems require you to search using information associated with the original call — the phone number it was placed from or the ticket number itself. You cannot search by address alone without also having the phone number or ticket number. If you need information about a ticket someone else called in, ask them for the ticket number or have them check the status themselves.
How long does a ticket stay in the system?
Tickets typically remain searchable for 30 to 90 days after they are created, depending on your state. After that window, they are archived and no longer appear in the standard lookup. If you need information about an old ticket, call 811 directly and explain that you need a historical record — they can usually retrieve it from their archives.
What if the lookup says a utility responded but I don't see any marks?
It means that utility confirmed it has lines at your location, but the marks may not be visible yet, may have faded, or may be in a spot you haven't checked. Walk the entire dig area carefully, including along the edges and in landscaping. If you still see no marks after a thorough search and the ticket shows "Marked," call 811 again with your ticket number and ask them to send crews back to refresh the marks.
Can I dig if one utility hasn't responded?
That depends on your state's rules and how much time has passed. Most states allow you to dig after two to three business days even if a utility hasn't responded, as long as you've made a good-faith effort to wait. Check your state's specific rules on the 811 center website, or ask the dispatcher when you call. When in doubt, wait the full required period — the cost of waiting is always less than the cost of hitting a line.
