One Call FAQs

Q: What are one call systems?

A: One call systems are comprised of member organizations that operate underground facilities in a specific geographic area (an entire state, a portion of a state or multiple states). One call systems allow the public to make a single phone call (or online request) a few days prior to digging to notify all affected utility operators with just one communication. One call systems are the first step and the central communications point in the damage prevention process.

Q: What are key areas of focus for one call systems?

A: One call systems are actively involved in all other CGA programs – educating the public about 811, collecting data about damages and near misses, establishing Best Practices for one call system operations, supporting CGA regional partner groups financially or with resources, establishing pilot programs for new technologies and building consensus to advocate for better state damage prevention laws.  

Q: How many tickets do one call systems process each year?

A: Reporting locate request ticket data is not required of one call systems, but a majority of systems do submit this information to CGA as part of the Damage Information Reporting Tool. Based on submissions from these one call systems, CGA estimates that at least 25 million locates are requested each year in the United States, resulting in more than 100 million outbound transmissions to member utility operators.
