The uniform numbers in American football

are unusual compared to those in any other sport. They are displayed in more locations on the uniform than in those of other sports (on both the front and back of the jersey, on both shoulders, and often on the helmet), and on the front of the jersey, they are displayed very large, taking up almost the entire front of the jersey. Just as importantly, certain numbers may only be worn by players playing particular positions; thus the jersey numbers assist the officials in determining possible illegal actions

 by players.

Unlike most other sports, in which teams have smaller rosters, American football players routinely have uniform numbers that cover the full range of numbers from 1 to 99. In other sports, where not as many numbers are needed, lower numbers are more traditional and are usually desired by players. But in American football, with the number of players on a roster sometimes exceeding 100, there is a need for many more numbers.

Most football leagues have a system in place that requires or otherwise encourages players in certain positions to be issued numbers within a certain range.

It should be noted that this NFL numbering system is based on a player's primary position. Also, if a player changes primary positions during his career, he does not usually have to change his number unless he changes from an eligible receiver to ineligible or vice versa (Jason Peters

 is a notable example, having moved between tight end, where he wore number 86, to offensive tackle, where he currently wears 71). Any player wearing any number may play at any position on the field at any time (though players wearing numbers 50-79 must let the referee know that they are playing out of position by reporting as an "ineligible number in an eligible position"). It is not uncommon for running backs to line up at wide receiver on certain plays, or to have a large lineman play at fullback or tight end in short yardage situations, or to have wide receivers fill in as extra defensive backs. Also, in preseason games, when teams have expanded rosters, players may wear numbers that are outside of the above rules. When the final 53-player roster is established, they are reissued numbers within the above guidelines.

The earliest numbering systems were significantly different from the modern variation. Until the 1920s, it was rare to see player numbers much higher than 25, and numbers had little correlation with positions (in 1929, the Orange Tornadoes

 instead of numbers.) The numbering system used today originated in football's past when all teams employed some variation of the single wing formation on offense. When teams switched to the T-formation in the 1930s and 1940s, the numbers were taken with them to whatever position evolved from the old single wing position. This numbering system originated in college football and was used only informally in the NFL until 1952; under the original somewhat informal system, the backs were numbered 1-4 and the line 5-8. Tailbacks, left halfbacks or flankers (1-back) were given 10s, Blocking backs or quarterbacks (2 backs) were given numbers in the 20s, fullbacks (or 3-backs) were given numbers in the 30s, and right halfbacks, what would become simply the halfback or running back (4-backs) in the 40s, centers in the 50s, guards in the 60s, tackles in the 70s, and ends in the 80s. Earlier, defensive players wore numbers that reflected their offensive position, as many players played both offense and defense. For example, quarterbacks and halfbacks usually played in the defensive back field and so had numbers in the 10s, 20s, and 40s. Fullbacks were linebackers and had numbers in the 30s; Centers and guards were linebackers as well and has numbers in the 50s and 60s respectively. Guards and tackles played the defensive guard and tackle positions and had numbers in the 60s and 70s respectively. Ends had numbers in the 80s. Split ends (e.g. Emlen Tunnell

NCAA

According to NCAA rule book Section 4 Article 1 recommends numbering as follows for offensive players;

Backs 1-49
Snapper 50-59
Guard 60-69
Tackle 70-79
End 80-99

Otherwise all player must be numbered 1-99, the NCAA makes no stipulation on defensive players. Two players may also share the same number
though they may not play during the same down.

The lowest numbers are often considered the most prestigious, and they are frequently worn not just by specialists and quarterbacks but also by running backs, defensive backs, and linebackers. Kickers and punters are frequently numbered in the 40s or 90s, which are the least in-demand numbers on a college roster. The increased flexibility in numbering of NCAA rosters is needed since NCAA rules allow larger rosters than the NFL; thus teams would frequently exhaust the available numbers for a position under the NFL rules. It is not uncommon for NCAA teams to have duplicate numbers, with an offensive player having the same number as a defensive one—this is allowed as long as both players are not on the field at the same time. Usually, one of the players will be a reserve who rarely plays, but this is not always the case: for example, the 2005 Texas Longhorns team had two key players who both wore #4: wide receiver Limas Sweed

High school

On high school and other lower youth teams, jerseys with different number ranges are different sizes, and since many of these teams don't reorder jerseys every year, players are often assigned numbers based more on jerseys that fit them rather than specific position (though the rules on numbering the offensive line still apply).
According to NCAA rule book Section 4 Article 1 recommended numbering is as follows

Backs 1-49
Snapper 50-59
Guard 60-69
Tackle 70-79
End 80-99
