CENTER HOURS OF OPERATION
The One Call Center is open 24 hours per day 7 days per week. During these hours, the call center staff is available to process your requests for locating and marking underground facilities in the vicinity of your excavation.
SERVICE AREA
The call center staff will process your request for locating and marking underground facilities anywhere in the five boroughs of New York City as well as Nassau and Suffolk Counties on Long Island. We will then notify facility owners who are participating members of our call center. (See our listing of these members.) Any facility owner who is not a member of our system will not be notified. (Please note that although membership is mandatory for all facility owners, not all facility owners have complied with that requirement.)
