Baseball players wear numbers on their jerseys so they can be identified.At all levels of baseball, players have numbers on their jerseys so fans, sports reporter and baseball officials can see who they are by the number they wear.

Each player has their own bat and the numbers correspond to the numbers on their jerseys.
The 1916 Cleveland Indians were the first team to wear numbers on their jerseys. The rest of the owners in baseball didn't like that idea and Cleveland quickly abandoned the jersey numbers. It wasn't until 1929 that they came back, when the New York Yankees started putting numbers on the back of the jersey. By 1931, the American League ruled that all team should put numbers on jerseys and in 1932 the National League followed suit.
The numbers and names are stiched on to real NFL jerseys. Fans can buy replica jerseys with numbers and names screen printed on for a lower cost.
It depends on the type of font the team uses on their jerseys
A lot of the older teams that were around 100 years ago don't wear their names on their jerseys, a combination of tradition, and the sentiment that "a true fan will know his player's numbers!"
