I am her oldest offspring and POA. You can NEVER get a live human when you call SSA, but I did see where one can create an account online. There are three disclaimers, however, that read,
"You can only create an account using your own personal information and for your own exclusive use.
You cannot create an account on behalf of another person or using another person's information or identity, even if you have that person's written permission.
For example, you cannot create an account for another person:
With whom you have a business relationship
For whom you are a representative payee, or
For whom you are an appointed representative.
Unauthorized use of this service may subject you to criminal or civil penalties, or both.
Does having POA overrule the above?
