Can a team in any state fundraise here without its own EIN?
Yes. Youth leagues, club programs, and school teams that do not have their own charity status can apply from any U.S. state. Tax-deductible gifts are received by Arizona Boosters Foundation, Inc., the 501(c)(3) parent (EIN 39-3080525), and directed to the approved team purpose. National Boosters Foundation does not hold a separate EIN.
