The Arizona Corporation Commission is the enforcement agency for the State of Arizona.

In 1973 the Underground Facilities Law was developed by contractors and underground facilities operators. In 1974, “Arizona Blue Stake” was established as a call center so underground facility owners and operators would be notified when anyone was planning to dig so they could mark their facilities in advance, in accordance with Arizona Revised Statute § 40-360.21-32. This law pertains to the entire State of Arizona and was often referred as the “Blue Stake Law”. The name Blue Stake comes from years past, when facility operators would use blue wooded stakes, driven into the ground, with a specific color painted on the tops of them. In 2005, the Federal Communications Commission (FCC) designated 811 as the national number to call before any type of digging so underground facilities could be located and marked, protecting lives and infrastructure from coast-to-coast. With the “one nation, one number” concept realized, anyone in any state can call 811 and be connected directly with their local one-call center. In 2014, “Arizona Blue Stake” officially changed its name to Arizona 811.

Arizona 811 Center is a damage prevention service offered free of charge to any individual or company planning to excavate, it is a one-call notification system established to assist excavators in locating all underground electric, gas, water, telephone, sewer, communications, or other lines prior to excavation.

Before you excavate, call the Arizona 811, it's the law!  Whether you're a homeowner or an experienced contractor, this is the safest way to prevent shocking or explosive surprises - surprises like underground electric, water, gas, cable, or telecommunications lines. One call to the Arizona 811 Center is all it takes and the utility will come out and mark the precise location of its lines for FREE.

Owners of underground facilities must locate and mark all their facilities at that location within 48 hours. Failure to do so could result in a fine of up to $5,000. You or a contractor cannot begin excavating until all utilities have been marked or be subject to a maximum fine of $5,000 per violation.
