Just got a call/msg from this number. BECU: Call. (theoretically the front four letters stand for Boeing Employee Credit Union.) There is a another number associated with the msg. 243 317 0304. This number is not a valid U.S. telephone number. The 978 631 0911 comes back to somewhere in Mass. This is clearly some sort of scam. I think I got zinged once before with the 978 exchange and the call goes to the Caribbean somewhere like the Dominican Republic. Calling the number back usually generates a very high call rate. The more calls, the more money they make and you are billed. Same time of day for the call (between 0800 and 0900 hours) on PDT. Note: if BECU was going to call me, it would have been a (800) type of number and a local number that would come back to them.
I just received a very similar message to Jim's. Mine came from 243-317-0311 but had a similar (BECU: Call 978 631 0911). It does appear to be some sort of scam.
