There have been about 2600+ numbers issued over the years. However, some teams have dropped out/coalesced with other teams due to various issues. Some never competed. (Say about 1100 for both groups.) Other teams have split into two or more teams, some of which have gotten old numbers... So 1500 is the right FRC estimate. Growth is at about 300 teams/year right now new team numbers.

Then you throw in the FLL teams. There is a cap there, I think it's about 5,000 in the U.S., but there are a lot more teams out there in other countries.

FTC--I have no idea how many teams are in this one.
