Where to write
PO Box 1532
Pennington, NJ 08534-0691
Address as registered with the IRS. Most foundations this size have no website and no application form, which is not a dead end: a short letter to this address is the whole process, and almost nobody sends one.
This address is a trust department, not an office. 421 other foundations file from the same address, which means a bank or a management company administers the trust. Put the full legal name of the fund and its EIN at the top of the letter, or it lands in a pile with thousands of others and nobody knows which fund you are writing about.
