Welcome to Merrimack Valley Credit Union!



Welcome Former RTN Federal Credit Union Members

The merger of RTN and MVCU has created a strong credit union offering former RTN members a wider range of products and services, additional branch access, and greater convenience.

While we are now one credit union, MVCU and RTN will not have integrated computer systems until approximately June of 2024.  In the meantime, continue to bank as you always would!  We encourage former RTN members to visit the same friendly faces at your usual branch(es) and manage your accounts with the same Online & Mobile banking you are used to.
