Line Calls Without Officials (The Code)
Also known as: The Code, USTA Code, line calling, calling lines, line call etiquette, bad line calls, opponent cheating, cheating on line calls, who calls the lines, unofficiated matches
In matches without officials, each player calls the balls on their own side of the net, and any doubt goes to the opponent. Calls must be prompt and clear, out loud or with a hand signal. If an opponent makes a pattern of bad calls, The Code says you may contact an official.
The Code is the USTA's guide to fair play in unofficiated matches, published in Friend at Court. Its core is simple. You call every ball landing on, or aimed at, your side of the net. You give your opponent the benefit of any doubt. A ball touching any part of a line is good, and a ball you cannot call out with certainty is good. You may not claim a let because you did not see the ball.
Make calls promptly, before your return goes out of play or the opponent has a chance to play it. Out calls must be audible or visible, even when the ball is obviously out. Spectators never make calls. If you call a ball out and then realize it was good, reverse the call. The point goes to your opponent and is not replayed. In doubles, either partner may call. If partners disagree, the ball is good. Except on the first serve, you should also call your own shots out when you clearly see them out.
When you think an opponent has made a bad call, their call still stands. Stay calm and keep playing your game. If bad calls form a pattern, The Code lets you contact an official, and you may refuse to play until one responds. Foot faults are a special case. The receiver may call one only if it is flagrant and warnings and requests for an official have failed.
Tips by skill level
Call the ball out loud or with a raised finger as soon as you see it out. If you are not sure, the ball is in.
Call every point the same way, from the first point to match point. The Code says all points are treated the same regardless of their importance.
Example
A league opponent calls a close baseline ball out. Lena is sure it was in but accepts the call and plays on. After two more doubtful calls, she asks the event desk for an official to watch the rest of the match.
Why it matters
Most recreational matches have no officials. Fair calls by the players are what keep the game working, and knowing The Code helps you handle disputes calmly.
Common mistakes
- Calling a ball out without clearly seeing space between it and the line
- Offering to replay a point you were unsure about. An unsure ball is good.
- Calling lines on your opponent's side of the net
- Arguing every call instead of contacting an official about a pattern

- Challenge System (Line Calls)The challenge system lets a player dispute a line call using electronic ball-tracking. Only a limited number of unsuccessful challenges are allowed per set.
- Foot FaultA foot fault occurs when a server's foot touches the baseline or crosses into the court before contacting the ball on the serve. It results in a fault.
- Let (Serve Rule)A let is called when a serve clips the net cord and still lands in the correct service box. The point is then replayed with no penalty to the server.
- Tennis ScoringPoints in a tennis game go love (zero), 15, 30, 40, then game, and the server's score is called first. At 40-40, called deuce, a player must win two points in a row to take the game. The first to six games wins the set by two, usually with a tiebreak at 6-6, and matches are best of three or five sets.
