Uniform Numbering System
In the NFL, players wear uniform numbers based on the position they play. This system was developed as a means for fans and officials to more easily identify players on the field by their position.
- Quarterbacks, placekickers and punters: 1–19
- Wide Receivers: 10–19 and 80–89
- Running backs and defensive backs: 20–49
- Offensive linemen: 50–79
- Linebackers: 50–59 and 90–99, or 40–49 if all are taken
- Defensive linemen: 60–79 and 90–99
- Tight ends: 80–89, or 40–49 if all are taken
