Give to NAAF through your workplace You can give to NAAF through your workplace if your employers participate in payroll deduction campaigns, like your local United Way or other federated campaigns by writing in the National Alopecia Areata Foundation and including our Federal Tax ID number: 94-2780249. If your employer participates in the Combined Federal Campaign (CFC), NAAF’s CFC code is 10589. If you have questions or need assistance, please contact Robbie Baker at (415) 851-8966.
