Secure your Arsenal account today

All Arsenal Credit Union accounts are monitored by a sophisticated 24/7 security system. But if you would like to take account monitoring into your own hands, consider signing up for online banking today. Having an online banking account allows you to continuously monitor your Arsenal accounts through your web browser or with your smartphone. Online banking can also be used to pay bills and transfer funds between accounts. To set up online banking, call us during normal business hours at 314.962.6363 (or 1.800.719.6363 outside of the St. Louis area) and say or press option 6, then option 2. You can also download the free mobile banking app for iPhone and Android.
