Be Aware of Scam Phone Calls Regarding ACH Transactions

Oostburg State Bank has been made aware that some customers may be receiving suspicious phone calls regarding ACH (Automated Clearing House) transactions. In these calls, individuals may claim to be from the Oostburg State Bank Fraud Department and ask questions about recent ACH activity on your account.

In some cases, the calls may even appear to come from an Oostburg State Bank phone number. The caller may ask for sensitive information such as your online banking username, password, or verification codes in an attempt to gain access to your account.

What You Should Know
