Every game's assignor is identified by the code at the front of the Type field in Horizon. Search any team or league below to find its assignor, their contact, and the rules for turnbacks and cancellations.
These apply to every official. When a rule points you to the game's assignor, use the directory below to find who that is.
For any game coded MCHO, use the “Click to Request Turnback” feature in Horizon whenever possible — it cuts email traffic and nothing gets lost. For other questions, email assignor@mchofficials.com.
Turnbacks within 72 hours of an MCHO game: call or text (312) 626-8577 right away. Never contact Brett, Dave, Mike, or Scott individually — the team works one shared line so whoever is on call can cover the game fast.
Games under any other code are turned back to that assignor, using the contact in the directory below. Their info also appears under the assignment in Horizon.
A minimum of 48 hours' notice is required to cancel, and individual assignors may require more. Cancellations are for emergencies only — repeat cancellations can cost you games or trigger fees.
A no-show is fined double the game fee. Assignors share no-show and cancellation history, and repeat offenders lose assignments across the board.
Worked a game alone? Notify that game's assignor that your partner no-showed — immediately if possible, and no later than 12 hours after the game.
Match the code from the Type field, or just search the team name. Tap a group to see every program that assignor covers.
