Due to caller ID spoofing (faking) your caller could be anyone anywhere in the world. Your question cannot be answered. Do you have friends/family in that area code? City? State? If the answer is no - time to move on. Please consider either not answering calls you do not recognize, or get a call blocking device (for land line), app (for cell phone). If you are in a situation where you must answer the phone, hang up immediately if it's someone you do not want to talk to, or are being threatened. Do not engage the caller.
