I have the same question too. Since the E-Sign section is right below the “Did anyone Assist you in filling out this application?” section, should I provide applicant Passport details (or) the Preparer passport details, which is my PP number
FYI : I selected Yes for the “Did anyone Assist you in filling out this application?” and filled my details and address. So the questions is only on whose PP number to enter in E-Sign section
Actually, you should write down the PPN of the applicants and not yours. I filled my son’s form and I tried to write down my PPN but I received this message so I tried again with my son’s PPN and it worked.
