Positive response: know the codes

Sunshine 811 processes nearly 2 million locate tickets each year. About half result in locate marks on the ground. But sometimes the marks – or lack of them – don’t tell the whole story. And that’s where Sunshine 811’s Positive Response System fills the gaps by telling you:

  • Which buried lines are marked
  • Which buried lines are not marked
  • When you need to provide, clarify or correct information

Get to know the codes.

1 Marked: A locate technician has been to your excavation site and marked the approximate horizontal location of underground facilities within the boundaries described on the ticket.


2A Marked with Exceptions: High profile utility in conflict; utility owner will attempt to contact you to schedule site surveillance.
This is a facility such as a fiber optic line that serves a large number of people. While it's located, the facility owner wants you to know that it requires careful digging. They will attempt to contact you if they want to be present to observe excavation.


2B Marked with Exceptions: Privately owned facilities on property; contact private facility owner directly
The public utility was located. Private facilities were not located. They can include, but are not limited to, parking lot lighting, fire mains, building to building utilities, electricity to sheds and garages, water or irrigation systems, gas to grills or pool heaters and landscape lighting. Try contacting the property owner or hire a private facility locator.


2C Marked with Exceptions: High-priority subsurface installation in conflict. Excavator MUST notify the member of the excavation or demolition start date and time.
The high-priority subsurface installation designation is for use by only those members that have underground transmission or distribution pipelines used to transport any gas, refined petroleum product or hazardous/highly volatile liquid such as anhydrous ammonia or carbon dioxide, if the facility is deemed to be critical by the operator of the pipeline and is identified as a high priority subsurface installation.

2D Marked with Exceptions: High profile utility in conflict. An underground facility that delivers service to a large number of people or that could cause major problems, if hit, is within your excavation site. Contact the utility if you want more information.

2E Marked with Exceptions: Marked within the confines of the white-lined area. 
A locate technician marked the approximate horizontal location of buried facilities WITHIN the white-lined area. (White paint, stakes or other white marks define the dig site boundary.) Any excavation outside the white-lined area requires a new ticket.

3A Unmarked: Locate technician could not gain access to property; call utility to schedule access.
Excavation site is unmarked. A utility’s locate technician was sent to the excavation site, but was unable to access the area to be marked due to a locked gate, blocked entrance, guard dog or other circumstance prohibiting entry. Call the utility to re-schedule a time when the entrance will be open.

3B Unmarked: Incorrect address information. Call Sunshine 811 to verify the information on the ticket.
Excavation site is unmarked because the address could not be found. Please call 811 or (800) 432-4770 to verify the address information and make adjustments to the ticket as necessary.

3C Unmarked: Locate technician and contractor (excavator) have agreed to meet on site on a specified date.
Excavation site is unmarked. The locate technician and excavator negotiated an alternate time to meet at the excavation site.

3D Unmarked: High profile utility in conflict; utility owner will attempt to contact you to schedule site surveillance. 
Excavation site is unmarked. An underground facility that delivers services to a large number of people or that could cause major problems if hit (i.e. fiber optic, gas or electric line, etc.) is located near your excavation site. The utility or locate technician want to be present during any excavation near that facility and will mark as necessary. The owner will contact the excavator to determine when excavation will take place.

3F Unmarked: Marking delay requested by locate technician and agreed to by excavator per agreement.
Excavation site is unmarked. The locate technician cannot mark within two full business days. The excavator was contacted and a new deadline was scheduled.

3H Unmarked: Privately owned facilities on property, contact private facility owner directly.
Excavation site is unmarked. A locate technician went to the excavation site and found none of the facility owner’s lines there; however, there are lines of a similar facility located in that area which are considered privately owned. This happens most often with customer-owned service lines

3M Unmarked: Marking instructions are unclear; call the utility to clarify the marking instructions
Excavation site is unmarked. The marking instructions on the locate ticket are not clear. The description may not make sense or the description may not match what the locate technician sees at the excavation site. Contact the utility to provide clarification.

3N Unmarked: Locate description is insufficient - white lining is required per s. 556.114(3), F.S. Please contact the utility when white lining is completed.
Excavation site is unmarked. Based on the written description on the ticket, the locate technician could not determine the exact area that needed locating. White lining is required per s. 556.114(3), F.S., when the written description of the area to be located is not understandable and when the marks don't interfere with traffic or pedestrian control (i.e. placing white marks on the ground could be confused with the lines already on pavement directing pedestrian and car traffic).

3P Unmarked: Utility does not have accurate information to perform the requested locate - please contact the utility for further details per s. 556.105 (7)(a), F.S.
Excavation site is unmarked. A utility does not have accurate information about the location of those underground facilities. The utility is required, however, to give the excavator the best available information.

3R Unmarked: The excavator has performed the excavation prior to the locator's arrival.
Excavation site is unmarked. A locate technician went to the excavation site, but the excavation work had already been completed.

3T Unmarked: Extraordinary circumstances per s.556.105(8)(a) exist; call utility owner/operator provider for this location.
Excavation site is unmarked. The utility has declared extraordinary circumstances through Sunshine 811 per s.556.105(8)(a) that render them unable to respond to your locate request. Extraordinary circumstances indicate situations other than normal operating conditions such as a natural or man-made disaster.

3U Unmarked: Not service provider for this location.
Excavation site is unmarked. Another company provides the services at this location. (i.e. Two phone companies provide services near the area where excavation will occur. Only one provides service at the exact excavation site. The company that does not provide service within the exact excavation site would use this code.)

3W Unmarked: Work is being performed by the utility and the excavator will mark the underground lines per agreement.

4 Clear, no facilities: The utility has no facilities at the specified excavation site.

5 No conflict: Utility is outside of the requested work site
The utility has a facility near the excavation site, but it is not within the area that was either described on the ticket or white lined.

6A Active facilities are present: The member has active facilities within the area described by the noticed demolition. Do not demolish until the member notifies you the site is clear.

8 Ongoing job: Locate technician and excavator have established an agreement on scheduled marking.
