This number called me on my cell phone at 9:30 AM. I answered but no one was there. The call then ended. I called back and there is a recording that does not sound like the phone company, and says "This number is not in service. Bye". It is an automated voice, likely a VOIP companies recording.
They're scam artists pretending to distribute education grants in exchange for an up-front fee. Real grants do not require payment to receive your funds.
This service just tells you what other people experience with a certain number. They aren't going to place on any call lists - it's for your info only. You can block the number yourself or report to the FTC/FCC for violating the Do Not Call registry.
