I signed up for AARP Supplemental Medicare plan a few days ago. I received a call from this number three times this morning, so I researched it here - Thank You!!!! I called the number suggested by someone else: 1-800-523-5800
and they confirmed that the call was a courtesy call from a third party, and asked if I had any questions. I gave them feedback that an email would be a better way to contact people because no one with common sense answers unidentified callers anymore. She made a note in my file so that future communications will be via email.
