California Code, Welfare and Institutions Code - WIC § 151

(a) The front of every collection box shall conspicuously display both of the following:

(b) If the collection box is owned by a nonprofit organization, the front of the collection box shall also conspicuously display a statement describing the charitable cause that will benefit from the donations.

(c) If the collection box is owned by a for-profit entity, the front of the collection box shall also conspicuously display a statement that reads “this donation is not tax deductible.” If the collection box is owned and operated by a commercial fundraiser, the commercial fundraiser may post notice of donations to a charitable cause only on the sides of the box. This notice shall always be smaller in size than the for-profit entity's name and address and shall constitute only 25 percent of the notice space of the box.
