An Independent Non-profit Organization

Audubon Canyon Ranch is a 501(c)(3) non-profit organization that relies on the generosity of individuals, corporations and foundations to fund its programs. ACR's tax ID # is 94-6069140. Any goods or services provided by ACR in exchange for gifts are insignificant under guidelines provided by the IRS, unless purchasing event tickets or specifically stated on your tax-receipt letter.  

Though ACR partners with local Audubon chapters in order to fulfill our mission, ACR is independent of the National Audubon Society and its chapters.
