USA North 811 (Underground Service Alert) manages all requests related to underground work. If there are markings at or near your home or office and you did not request them, please direct questions to 811.
Anyone performing digging or underground work must have a USA ticket, so utility lines can be marked in advance of work being performed, to prevent safety hazards. USA North can advise of the agency or the party who placed the request. Contact USA North by calling 8-1-1.
