ND One Call Center has adopted a “Holiday Substitution Policy” so that excavators and operators are better aware, in advance, of what days ND One Call Center will observe all holidays. If a holiday falls on a Saturday, ND One Call Center will observe the Friday before as the holiday; if it falls on a Sunday, ND One Call Center will observe the Monday after as the holiday.

ND One Call Center is open 24 hours, seven days a week. North Dakota recognizes the following holidays:

New Year’s Day | Martin Luther King, Jr’s Birthday | Presidents Day | Good Friday | Memorial Day | Independence Day | Labor Day | Columbus Day | Veterans Day | Thanksgiving | Christmas
