Have received numerous calls from this number. A message was left saying it was the United States Census Bureau and for me to call 1-888-419-7586 regarding a case number. This call was on 11/8 when the message was left. They called again on 11/10 but no message. The only thing I can think it might be related to would be the American Community Survey which I submitted after months of phone calls. I gave only the minimal info. It is very intrusive and none of their business as far as I'm concerned.
