NTEE codes: the IRS Exempt Organizations Business Master File (published) and, for organizations the IRS lists without one, a code inferred by a small language model from the name and Form 990 text (inferred, with the model's confidence). Taxonomy: NCCS at the Urban Institute. The stated code is what the IRS lists, assigned once and rarely revisited, so it is often wrong: see the caveat and examples.
