1. All players of a team must be dressed uniformly in matching jerseys, pants, socks, and helmet.

2. All jerseys of a team must be of the same design, including logo on the front, numbers on the sleeves and back, and nameplate on the back.

3. Players are not allowed to tamper with their uniforms in any manner, whether by cutting any part of it, writing on it, or marking it.

4. If, in the opinion of the referee, the uniform colours of the competing teams are so similar that there is the possibility of misidentifying players, it is the responsibility of the home team to change its jerseys.

5. The dominant colour of the uniform must cover approximately 80 % of the jersey and socks, excluding names and numbers.

6. Jerseys must be worn entirely outside of the pants and whenever possible be properly fastened to the pants with tie-down straps.

7. Jerseys must follow the contours of the player’s body and not be excessively baggy.

8. Jerseys must not extend length-wise past the end of the pants, and the sleeves must not extend past the fingers of the glove.

9. Each player must wear a number that is 25 – 30 cm high on the back of the jersey and 10 cm high on both sleeves. Numbers are limited to whole numbers from 1 to 99 (no fractions or decimals).

10. No two players on a team may use the same number in the same game.

11. Players are not allowed to change or exchange jersey numbers once the game has started. They must wear their number for the game’s entirety and throughout the tournament or event.

12. The only exception to Rule 40-11 is if a player’s jersey becomes stained with blood or becomes badly torn during a game. At that point, he may be told by an on-ice official to leave the ice and change into a designated jersey with another number and no nameplate.

13. A player whose hair is long enough to obscure the nameplate or number on the back of the jersey must fashion it in a ponytail or tuck the hair under the helmet.

14. Graffiti-type designs, patterns, artwork, drawings, or slogans which are abusive or obscene and refer to culture, race, or religion are not allowed on any part of the uniform.

15. In IIHF competitions, each player must wear his name on the upper portion of the back of his jersey, printed 10 cm high, in block capital Roman letters of a font approved by the IIHF prior to the game or tournament.

16. All players on a team must wear the same uniforms and jersey numbers in the pre-game skate as they do during the game.

17. Players who do not comply with these provisions are not allowed to participate in the game. Failure by any player on that team to comply after a warning will result in a minor penalty for delay of game.
