The Short Answer

Phones must be silent during rated games. If your phone makes a sound during play, you may forfeit the game — even if you weren’t using it. The safest approach: turn it off or leave it outside the playing hall.

Official source note: USCF and FIDE phone rules have been updated multiple times. Policy details vary by event. Always check the specific tournament rules and verify current federation policy at uschess.org or fide.com.

The Core Rule

USCF rules state that electronic devices — including phones — must be turned off or set to silent/airplane mode during play. Players are not allowed to use phones to look up positions, receive outside assistance, or communicate about the game while it is in progress.

If your phone emits any sound during a game (ring, notification, alert), the tournament director may forfeit you, regardless of whether you were using the phone. This is a strict rule at many events.

FIDE vs. USCF Rules

FIDE (international play): FIDE has strict rules requiring phones to be off and stored, not just silenced. At elite events, phones may need to be surrendered before the round. A phone ringing during an FIDE game can mean an automatic forfeit.

USCF (most US club and scholastic events): The rules are similar in intent but enforcement varies by tournament. Some tournaments are strict (any sound = forfeit); others issue a warning for a first offense.

Read the specific tournament’s rules section before round 1. The TD will usually announce the phone policy at the players’ meeting.

What “Silent” Actually Means

Silent mode is not always enough. Vibrations can be audible in a quiet playing hall. Notification sounds can still occur even when a phone is on silent if certain alert categories are enabled. The safest options are:

  • Airplane mode — no signals in or out, all sounds off
  • Powered off — best option for compliance
  • Left in a bag outside the hall — eliminates risk entirely

Do not rely on “I thought it was on silent.” If your phone makes any sound, you are responsible.

What Happens If Your Phone Goes Off

  1. The sound is heard by your opponent or the TD
  2. Your opponent may claim a forfeit, or the TD may act independently
  3. The TD investigates and makes a ruling
  4. You may forfeit the game, receive a warning (at the TD’s discretion), or continue depending on event rules

Whether you receive a warning or immediate forfeit depends on the tournament’s policy and the TD’s judgment. At major events, the forfeit is typically automatic. At smaller club events, a first offense may result in a warning.

What About Using Your Phone Between Moves?

Do not use your phone for anything chess-related during a game — including between moves on your opponent’s time. Looking up positions, using an engine, or receiving coaching through a phone is cheating and can result in forfeiture and potential suspension from rated play.

Using your phone for non-chess purposes (reading a text, checking the time) while your opponent is thinking may also be prohibited depending on the event rules. When in doubt, don’t use your phone at all during a game.

For Parents

Parents watching from outside the playing hall should also keep phones silent. Some events enforce rules about noise in adjacent areas as well.

If your child’s phone goes off during a game and you gave them the phone, it’s still the player’s responsibility. Make sure phones are powered off before the player enters the hall.

Quick Checklist Before Each Round

  • Phone powered off or in airplane mode
  • Vibration off
  • Phone stored in bag (not on the table or lap)
  • Earbuds or smartwatch notifications disabled
