Rugby league numbers 1–13—and why World Cup shirts can differ
Learn rugby league shirt numbers 1–13, interchange numbers 14–17, and why international World Cup squad numbers may not match positions.
In thirteen-a-side rugby league, the traditional shirt numbers run from 1 at fullback to 13 at loose forward, with 6 and 7 forming the halves and 9 identifying the hooker. Numbers above 13 commonly identify interchange players—but a World Cup shirt number does not always tell you a player’s position.
This is rugby league’s numbering system, not rugby union’s. For an international team sheet, start with the conventional positions below, then check whether the numbers are match-day positions or squad numbers.
What each rugby league number means
The IRL’s 2024 International Laws, Section 4, set out seven backs numbered 1–7 and six forwards numbered 8–13. The table follows that numbering, with brief descriptions of the usual roles.
| Number | Position | Usual role |
|---|---|---|
| 1 | Fullback | Covers behind the defensive line, fields kicks and joins attacks. |
| 2 | Right wing | Attacks and defends the right flank; finishes chances out wide. |
| 3 | Right centre | Creates opportunities for the right winger and defends that side. |
| 4 | Left centre | Creates opportunities for the left winger and defends that side. |
| 5 | Left wing | Attacks and defends the left flank; finishes chances out wide. |
| 6 | Stand-off / five-eighth | Helps direct attacks through passing, running and kicking. |
| 7 | Scrum-half / halfback | Organises play and links the forwards with the backs. |
| 8 | Prop | Carries into contact and tackles through the middle. |
| 9 | Hooker | Commonly passes or runs from dummy-half after the play-the-ball. |
| 10 | Prop | Shares the front-row carrying and defensive workload. |
| 11 | Second-row forward | Combines running, tackling and handling. |
| 12 | Second-row forward | Shares the second-row running and defensive work. |
| 13 | Loose forward / lock | Combines tackling, carrying and handling; packs at the back of the scrum. |
These are broad responsibilities, not exclusive duties. Shevington Sharks’ positions guide explains the roles, including the hooker’s frequent work at dummy-half. Dummy-half is the player collecting the ball immediately after a teammate plays it. It is a role during a passage of play, rather than a separate numbered position: any player can act as dummy-half.
“Stand-off” and “five-eighth” name the same position; so do “loose forward” and “lock”. A team sheet using different terminology is not necessarily describing a different formation.
What do numbers 14–17 mean?
When traditional positional numbering is used, 14–17 are the four interchange players, not four additional positions. A replacement can take over a role on the field without changing their shirt number. The 2024 international laws provide for thirteen players on the field and four nominated replacements, with an additional 18th-player replacement available under specified injury conditions.
Why World Cup numbers can differ
International tournament line-ups can depart from the traditional positional numbers. At the men’s World Cup played in 2022:
- Dominic Young wore 14 but started on the wing for England against Samoa.
- Josh Addo-Carr wore 9 but started on the wing for Australia against Fiji.
- Ben Hunt wore 3 and started at hooker in that same Australia match.
The NRL’s official Round 1 team lists record both the numbers and the positions. They show why reading “9” as “hooker”, or “14” as “substitute”, can misidentify a player in an international archive.
For historical research, record shirt number, named position and starter/interchange status separately. The traditional number is a useful guide; the match’s actual team sheet is the evidence for where a player was selected.
