Passes are shipped without a name on them and passes issued will only allow one signature. Photo identification will be required to verify ownership.
Remember the Annual Pass will admit entry for the pass holder and passengers in a private, non-commercial vehicle at sites that charge per-vehicle entry fees. If you visit a site that charges per person entry fees then your Annual Pass will cover you and 3 additional adults (children 15 and under are always FREE) for a maximum of four adults.
