Called but left no message. Have no idea who this is. The caller ID on my cell just said Chattanooga, TN.

This is the number for Blood Assurance

Have gotten a few calls from this number over the past month.  I do not answer as I live in Oregon and do not have any ties to Tennessee nor do I know anyone that lives there.  They never leave a message.  From what I am gathering from googling the number, they are a company called Blood Assurance, but honestly I have no idea why they would be calling me!

Yes; this is the number for Blood Assurance. They call people who are on their donor list when blood supplies are low in the region. I have no idea why they would call someone in Oregon unless a number was entered incorrectly into their database. They called me today asking  if I would donate blood this week.

It's Blood Assurance. If you've donated before they are probably calling to say they need your blood type but Idk why the Chattanooga branch would call you if you live in Oregon.
