REMINDER: DIG/INSTALL SAFELY!

Planning to dig for any reason or install anything into the ground using tools?

Arizona 811 (formerly Arizona Blue Stake) cares about your safety and reminds you to “know what’s below” before doing any type of digging or installing anything into the ground using tools. Knowing the location of buried gas & water pipes, highvoltage electric wires, and high‐speed fiber & other telecommunications cables, then carefully working around them, helps protect you or your volunteers/supporters from serious injuries and prevents damage to the critical utilities we all rely on every day.

Why is it important to contact Arizona 811 before you dig? For decades, utility providers installed thousands of miles of underground pipelines, wires, cables, and other equipment across Arizona. Today, that complex utility network is buried beneath homes and schools, businesses and roadways, parks, open spaces, forests and farms. These utilities are key parts of the critical infrastructure that enables Arizona’s economy and quality of life to thrive. Keeping these utilities from being inadvertently damaged is a role in which
everyone can participate.

For your safety, the Arizona Underground Facilities Law requires underground utilities to be located and marked before any type of “excavation” or “digging”, which includes installing anything into the ground using tools.

Get prepared in advance by identifying a list of locations where you are planning to do any digging or installations, then follow this FREE process. It’s as EASY as 1, 2, 3:


1. Contact Arizona 811 not less than 2 working days before you plan to start working. You can:

  • Call the simple three‐digit number, 811, from anywhere in Arizona; or
  • Submit requests for markings online by clicking Arizona811.com and signing up for E‐Stake.


  • 2. The facility owners will respond in 2 working days by marking the location of their underground utilities or by informing you they have nothing in the area.


    3. Dig or install items at least 24 inches from any mark. If you will be closer than 24 inches, only use hand tools to carefully identify the location of utilities before commencing with your digging or installations.

    If you have any questions at all, call us at 811! We are always here to help you!
