So I am new to an OCC bank and was wondering about reporting fraud. We had someone duplicate our cashiers checks and they have been sending them out nationwide in a secret shopper packet. Now obviously we have very limited information on who the people are doing this but we have enough to file a SAR. Do we need to contact the OCC to make them aware in any other way?

Have to, no - can you, yes:

Thanks Randy!

The OCC to my knowledge is the only federal bank supervisory agency that still publishes public alerts about fraudulent cashiers checks and similar scams. The FDIC used to do it, but may now be announcing them only via their secure portal for insured bank representatives.
