I have received 3 text messages, one from 800-881-4393 and the other two from 888-674-7619.  All messages say it is from a credit union.  The messages are "urgent update" or "call us now".  The call back numbers are 717-207-9230 or 817-350-4570.  After an internet search 717-207-9230 is linked to Janel Widdowson of the Sertoma Club of Lancaster Pennsylvania.  The info I found for the 817-350-4570 states that it is a scam (817 is the area code for Tarrent County, Texas).
