That depends! Clubs are welcome to fundraise, but the intended use of those funds matters.
Donations and fundraising specifically for Girls Who Code will go toward our general operating expenses and not a specific Club/school/volunteer. These donations will be directed to Girls Who Code as an organization, and the GWC Tax ID can be provided.
But since all Clubs are hosted at non-profits like schools and libraries, individual Clubs can work with their host site to fundraise in whatever way makes sense. This way, the Club may get to use all the money they raise. When fundraising for their own Club, fundraisers should to use the Tax ID of the host organization, not GWC.
