Minnesota solicitation registration

Not found in the Minnesota Attorney General soliciting-charities registry. That can be legitimate: organizations raising under $25,000 with no paid staff, and religious organizations, can be exempt from registration. Out-of-state charities that do not solicit in Minnesota also do not register.

Before you donate

Check recent impact reporting, identify the specific program your donation supports, and compare the organization with similar groups. Donation processing through Charity Buddy is not active.
