Handle (or as North Carolina calls it, total wagering revenue) is the amount bet within a state each month on sports. Customers must be physically located within the state to use legal, regulated sportsbooks. Revenue (the formal term for that in the Tar Heel State is Gross Wagering Revenue) is the money left after operators pay out winnings to bettors. Total wagers are calculated by adding paid wagering revenue to promo wagering revenue; operators offer North Carolina sports betting promo codes to their customers.
