Core Transformation Resources
MIT FCU's core transformation will occur from Friday, October 31st through Monday, November 3rd, 2025. Here's what you need to know.
Getting ready for transformation.
A credit union core is the central technological backbone that powers a credit union's operations, such as managing member accounts, processing transactions, and managing loans. MIT Federal Credit Union will be undergoing an upgrade to its core system, which will provide enhanced service, technology, and security for its members. Core transformation is a significant change to the Credit Union, and our employees are working hard to make sure the transition is as easy as possible for our membership.
MIT FCU's core transformation will take place from Friday, October 31st through Monday, November 3rd, 2025. During this time, account access will be unavailable.

Providing our members a better banking experience
