What is the abbreviation for the term none profit organization?

Question

I am doing a letterhead for my our school forum group and I need to include that this is a none-profit organization.

Answer 1

simply NPO or you can use charity, foundation, socio-civic organization, non-commercial...

Answer 2

It's just NPO.  If you've been trying to find it, you're probably having no luck because it's "non-profit", not none profit! :-)

Answer 3
