I applied under Additional Types, Sports Team (community). That was the best description for us.
On the verification letter, it defaulted us to a non-profit organization and pointed us to a Publication with information about applying for tax exempt status. We weren't planning on doing that for this limited scope because I had heard that there were additional steps and it didn't seem worth it to us.
"When you submitted your application for an EIN, you checked the box indicating
you are a non-profit organization. Assigning an EIN does not grant tax-exempt status
to non-profit organizations. Publication 557, Tax-Exempt Status for Your
Organization, has details on the application process, as well as information on
returns you may need to file. To apply for recognition of tax-exempt status under
Internal Revenue Code Section 501(c)(3), organizations must complete a Form
1023-series application for recognition. All other entities should file Form 1024 if
they want to request recognition under Section 501(a).
Nearly all organizations claiming tax-exempt status must file a Form 990-series
annual information return (Form 990, 990-EZ, or 990-PF) or notice (Form 990-N)
beginning with the year they legally form, even if they have not yet applied for or
received recognition of tax-exempt status."
