Fraud Alert

Scammers may pose as ACU of Texas employees and call from fake ACU of Texas phone numbers to gain access to your personal information. While ACU of Texas may call you from time to time to enhance your membership, for security reasons, we will NEVER ask for your full account number, card number or social security number. If you are contacted by anyone requesting your full account number, card number or social security number or feel uncomfortable in any way, you should end the communication and contact our Member Access Center at 409.945.4474 or 281.479.3441 or visit one of our 15 branch locations.


What should I do if my MasterCard® Debit or Credit Card is lost or stolen?

Contact the Member Access Center at 281.479.3441. Hours of operation are Monday through Friday from 8 a.m. - 7 p.m. and Saturday from 9 a.m. to 5 p.m.
