Didn't recognize #; caller ID just said "HONESDALE PA" (yes, with the gap in the center). Googled the # and another report site had ALREADY flagged it as some sort of health insurance spam call....

6th call from "SAYRE PA" since early March. Only difference is the last 4 digits each time. This time? Picked up & immediately hung up when I saw the caller ID....

Caller ID said "Name Unavailable". I can't count how many calls which have come up on the caller ID that way. So picked up & hung up on general principle.

No message left by "Name Unavailable" even though call went to voicemail. Another site ALREADY had # flagged as "invalid or not belonging to the US" when I looked it up! Clearly some flavor of scam....

6th call from this area code/exhange in a month. 27th since Jan. which came up as "Name Unavailable" on the caller ID. NO hits on Google. And another report site said # was either "Invalid" or "NOT a US #". I'd call that a Fraud Call, too....

Caller ID said "MILTON PA" (the gap is a red flag that it's NOT a legit call -- possibly to fake out caller ID software). Picked up & hung up at once. Almost no info on Google for the # (I'm fixing that -- you're welcome). Also reported # to the FTC....
