You also have to indicate a legal mailing address, perhaps General Delivery at your Post Office.
You also need to get in writing a letter on letterhead from a social service agency that states you are homeless and you live at the physical address you stated, i.e., east bank of the XYZ River, between Bubba’s Auto and Main Street, My Town, Montana.
