In the very early years, there were no team numbers, just names. Then for a few years teams got new numbers every year. Starting in 1998 permanent team numbers were assigned. Those already in the program were assigned alphabetically. Juggernauts became team #1 because their sponsor that year started with a number, and sorted lowest.

• Teams #1-#208 were rookies in or before 1998 (this is due to FIRST giving teams new numbers every year previously).
• Teams #209-#335 were rookies in 1999.
• Teams #336-#491 were rookies in 2000.
• Teams #492-#716 were rookies in 2001.
• Teams #717-#999 were rookies in 2002
• Teams #1000-#1238 were rookies in 2003.
• Teams #1239-#1497 were rookies in 2004.
• Teams #1498-#1709 were rookies in 2005.
• Teams #1710-#1980 were rookies in 2006.
• Teams #1981-#2287 were rookies in 2007.
• Teams #2330-#2681 were rookies in 2008.
• Teams #2702-#3122 were rookies in 2009 (no even numbers between 2702 and 2826).
