Phone Call Scam Alert
Fraudsters are increasingly making unsolicited calls to bank customers that may come from a spoofed phone number that looks like it’s from Stellar Bank. The caller may create a sense of urgency, and may say they need to verify a suspicious or unauthorized transaction.
When someone calls you unexpectedly, never share sensitive information. Stellar Bank may need to verify personal information when you call us directly, but NOT the other way around.
If you receive an unsolicited call claiming to be from Stellar Bank and are sent a Secure Access Code, do not share the code. Ask for the employee’s name, end the call, and then contact Stellar Bank directly at 713.499.1800 to confirm the request.
