It's probably a scammer looking to steal your ID or cash.
Can you find a call blocker or call-blocking service to block the number? If yours is a land line, your phone provider might offer a blocking service, so I would check with them. There are call blockers you can buy, and phones that have call blockers built in, too.
If it's a smartphone, they all have call-blocking ability. Check with your phone's app store. For dumb phones, you could set up a contact with a name like SCAM, assign this number to that contact and then assign a silent/no vibrate ring tone. That way you won't be bothered by the call.
I suspect yours is a land line though, so try Googling CALL BLOCKER and see if one fits your system.
