It is a SCAM number. Caller, most likely with accent, informs you that you have been selected to receive a government grant for thousands of dollars (my sister's alleged amount was $10,000). All she would need to do is call this number and get an access code, go to Walgreens, and they would Western Union the money. It would only cost her $250 and, of course,  that money would be refunded wlong with her $10K.
Government does NOT randomly select individuals for grants-EVER!!! Individuals are NOT eligible. to receive grants.
