  • Join Arsenal for some Minion mischief: All members age 12 and under are invited to join our kids club mascot, Tracker, for a showing of the Minions movie at Wehrenberg Ronnies 20 Cine in South County on Saturday, July 18. The movie begins at 11:30 a.m. Kids club members will be admitted for free, while adults and guests pay just $6.75 per ticket! All members planning to attend should RSVP to Arsenal’s Marketing Coordinator, Jenny Remes, by calling 314.919.1006 or sending an email to by July 15. Please keep in mind that all children attending must be accompanied by a parent or guardian age 16 or older. Arsenal Credit Union and Wehrenberg Ronnies 20 Cine are not responsible for the care of attendees.

    The Credit Union Advantage: When it comes to the united strength of financial cooperatives, big banks simply can’t compete. Arsenal is one of roughly 1,800 credit unions in the nation that participates in the CO-OP Shared Branch Network, the third largest financial infrastructure in the U.S. with 5,341 branches – that’s nearly 100 more locations than Bank of America (5,244) – and with your Arsenal membership, you have unbridled access to all of them. Combined with the CO-OP ATM Network, you can also take advantage of nearly 30,000 free ATMs throughout the country, enabling you to access your money at more places and times than any single big bank can offer. With the credit union advantage, yes, you are that powerful.

    Improvements in Progress: Arsenal Credit Union’s core data processing system will soon be undergoing an upgrade. This means that certain Arsenal products and services will be temporarily unavailable or have limitations on their usage during this time. For more information, including upgrade dates, affected products and services, ways you can prepare, and how the upgrade will enhance the future of financial management at Arsenal Credit Union, click here for FAQs.

    And then there was one: Arsenal would like to remind former SIACU members and small business members that, effective May 30, 2015, the credit union’s primary and only routing/transit number is 281081233. Routing numbers that such members may have been using other than the credit union’s primary number are being retired on May 29. Any trailing activity with the old numbers after this date will be returned or rejected. Our primary routing number is published on both our Checking Accounts page and Direct Deposit page should anyone ever need to know and use it.
