What's this talk about "joining" Dupaco? Well, a credit union like Dupaco is a not-for-profit financial co-operative, so when you open an account you are joining as a member of the co-operative.

Joining Dupaco is easy and smart, because our members save money (low- and no-fee services and lower loan rates) and make money (high dividends). And Dupaco members have access to numerous products and services (even insurance and wealth management) and the experts who will help you put them all to good use.

Join today!

You are eligible to join Dupaco if you live or work within our charter area, illustrated below, or have an immediate family member who is a Dupaco member. To become a member, simply open a savings account with $25 or more. Even if you move you can still take advantage of all Dupaco's service offerings as long as you keep at least $25 in your savings account.
